Accounting Policies [Abstract]
Accounting Policies	Accounting Policies
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly owned and majority-owned subsidiaries. In addition, the Company has joint ventures that are consolidated in accordance with consolidation accounting guidance. All intercompany accounts and transactions are eliminated.
	Accounting for Highly Inflationary Economies
	The Company has a subsidiary in Venezuela using accounting for highly inflationary economies. Currency restrictions enacted by the Venezuelan government have the potential to impact the ability of the Company's subsidiary to obtain U.S. dollars in exchange for Venezuelan bolivares fuertes ("Bolivars") at the official foreign exchange rate. In 2014, the Venezuelan government announced the expansion of its auction-based foreign exchange system (SICAD1). The Venezuelan government also introduced an additional auction-based foreign exchange system (SICAD2) which permits all companies incorporated or domiciled in Venezuela to bid for U.S. dollars. As of January 3, 2015, the SICAD1 and SICAD2 exchange rates were 12.0 and 51.0 Bolivars per U.S. dollar, respectively.
	Although the functional currency of the Company's operations in Venezuela is the U.S. dollar, a portion of the transactions are denominated in local currency. The Company has historically applied the official exchange rate of 6.3 Venezuelan Bolivares fuertes per U.S. dollar to remeasure local currency transactions and balances into U.S. dollars. However effective January 3, 2015, the Company concluded that it was appropriate to apply the SICAD2 exchange rate of 51.0 Venezuelan Bolivares fuertes per US dollar as it believes that this rate best represented the economics of its business activity in Venezuela at that time. As a result, the Company recorded a $10.4 million devaluation charge in the fourth quarter of 2014. Going forward, any devaluation in Venezuela will result in a reduction in the U.S. dollar reported amount of currency denominated revenues, expenses and, consequently, income before taxes. At January 3, 2015, the Company had approximately $1.3 million of exposed net monetary assets denominated in Bolivars. During February 2015, additional changes to the exchange rate mechanisms were announced, resulting in SICAD2 being replaced by a new mechanism called “SIMADI” that could result in further devaluation during 2015.
	Use of Estimates
	The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”), which require the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and revenues and expenses during the periods reported. Actual results could differ from those estimates. The Company uses estimates in accounting for, among other items, allowance for doubtful accounts; excess and obsolete inventory; share-based compensation; acquisitions; product warranty obligations; pension assets and liabilities; derivative fair values; goodwill and other asset impairments; health care reserves; retirement benefits; rebates and incentives; litigation claims and contingencies, including environmental matters; and income taxes. The Company accounts for changes to estimates and assumptions when warranted by factually based experience.
	Acquisitions
	The Company recognizes assets acquired, liabilities assumed, contractual contingencies and contingent consideration at their fair value on the acquisition date. The operating results of the acquired companies are included in the Company’s consolidated financial statements from the date of acquisition.
	Acquisition-related costs are expensed as incurred, restructuring costs are recognized as post-acquisition expense and changes in deferred tax asset valuation allowances and income tax uncertainties after the measurement period are recorded in income tax expense.
	Revenue Recognition
	The Company generally recognizes revenue upon transfer of title, which generally occurs upon shipment of the product to the customer. The pricing of products sold is generally supported by customer purchase orders, and accounts receivable collection is reasonably assured at the time of shipment. Estimated discounts and rebates are recorded as a reduction of gross sales in the same period revenue is recognized. Product returns and credits are estimated and recorded at the time of shipment based upon historical experience. Shipping and handling costs are recorded as revenue when billed to the customers. The costs incurred from shipping and handling are recorded in Cost of Sales.
	The Company has certain operating leases in the oil and gas industry where revenue is recognized over the term of the lease. The lease revenue is not material for all fiscal periods presented. The related net leased assets were not material at January 3, 2015 and December 28, 2013 and were included in Other Noncurrent Assets.
	The Company derives a significant portion of its revenues from several original equipment manufacturing customers. Despite this relative concentration, there were no customers that accounted for more than 10% of consolidated net sales in fiscal 2014, fiscal 2013 or fiscal 2012.
	Research and Development
	The Company performs research and development activities relating to new product development and the improvement of current products. The Company's research and development expenses consist primarily of costs for: (i) salaries and related personnel expenses; (ii) the design and development of new energy efficiency products and enhancements; (iii) quality assurance and testing; and (iv) other related overhead. The Company's research and development efforts tend to be targeted toward developing new products that would allow it to gain additional market share, whether in new or existing segments. While these costs make up an insignificant portion of operating expenses in the Power Transmission Solutions segment, they are more substantial in the Climate Solutions and Commercial and Industrial Systems segments. In particular, a large driver of research and development efforts in the Climate Solutions and Commercial and Industrial Systems segments is energy efficiency.
	Research and development costs are expensed as incurred. For fiscal 2014, 2013 and 2012, research and development costs were $32.9 million, $28.3 million and $28.5 million, respectively. Research and development costs are recorded in Operating Expenses.
	Cash and Cash Equivalents
	Cash equivalents consist of highly liquid investments which are readily convertible to cash, present insignificant risk of changes in value due to interest rate fluctuations and have original or purchased maturities of three months or less.
	Concentration of Credit Risk
	Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash equivalents. The Company has material deposits with a global financial institution. It performs periodic evaluations of the relative credit standing of its financial institutions and monitors the amount of exposure.
	Concentration of credit risk with respect to trade accounts receivable is limited due to the large number of customers and their dispersion across many geographic areas. The Company monitors credit risk associated with its trade receivables.
	Investments
	Investments include term deposits which have original maturities of greater than three months and remaining maturities of less than one year. The fair value of term deposits approximates their carrying value. These investments are included in Prepaid Expenses and Other Current Assets on the Company's Consolidated Balance Sheets.
	Trade Receivables
	Trade receivables are stated at estimated net realizable value. Trade receivables are comprised of balances due from customers, net of estimated allowances. In estimating losses inherent in trade receivables the Company uses historical loss experiences and applies them to a related aging analysis. Determination of the proper level of allowances requires management to exercise significant judgment about the timing, frequency and severity of losses. The allowances for doubtful accounts take into consideration numerous quantitative and qualitative factors, including historical loss experience, collection experience, delinquency trends and economic conditions.
	In circumstances where the Company is aware of a specific customer's inability to meet its obligation, a specific reserve is recorded against amounts receivable to reduce the net recognized receivable to the amount reasonably expected to be collected. Additions to the allowances for doubtful accounts are maintained through adjustments to the provision for doubtful accounts, which are charged to current period earnings; amounts determined to be uncollectable are charged directly against the allowances, while amounts recovered on previously charged-off accounts benefit current period earnings.
	Inventories
	At the beginning of fiscal 2013, the Company changed its inventory valuation method for the finished goods of recently acquired North American businesses to the last-in, first-out ("LIFO") method from the first-in, first-out ("FIFO") method. The Company believes the change to the LIFO method is preferable because it will improve matching of current costs with revenues when there is volatility in the cost of raw materials, and is consistent with the method used for the majority of the Company’s other North American finished goods inventory. Prior period consolidated financial statements have not been retroactively adjusted. The cumulative effect of this change was immaterial.
	The approximate percentage distribution between major classes of inventory at year end is as follows:
		January 3,			December 28,
		2015			2013
	Raw Material and Work In Process	45	%		41	%
	Finished Goods and Purchased Parts	55	%		59	%
	Inventories are stated at cost, which is not in excess of market. Cost for approximately 52% of the Company's inventory at January 3, 2015 and 49% at December 28, 2013 was determined using the LIFO method. If all inventories were valued on the FIFO method, they would have increased by $47.2 million and $58.2 million as of January 3, 2015 and December 28, 2013, respectively. Material, labor and factory overhead costs are included in the inventories.
	The Company reviews inventories for excess and obsolete products or components. Based on an analysis of historical usage and management's evaluation of estimated future demand, market conditions and alternative uses for possible excess or obsolete parts, the Company records inventories at the lower of cost or market.
	Property, Plant and Equipment
	Property, Plant and Equipment are stated at cost. Depreciation of plant and equipment is provided principally on a straight-line basis over the estimated useful lives (3 to 50 years) of the depreciable assets. Accelerated methods are used for income tax purposes.
	Expenditures for repairs and maintenance are charged to expense when incurred. Expenditures which extend the useful lives of existing equipment are capitalized and depreciated.
	Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized. Leasehold improvements are capitalized and amortized over the lesser of the life of the lease or the estimated useful life of the asset.
	The Company evaluates property, plant and equipment whenever events or circumstances have occurred that may indicate that carrying values may not be recoverable. If an indicator is present, the Company evaluates carrying values as compared to undiscounted estimated future cash flows. If such estimated future cash flows are less than carrying value, an impairment would be recognized. See also "Long-Lived Assets" in this footnote for the results and additional details of the impairment of certain long-lived assets and related charges.
	Property, plant and equipment by major classification was as follows (in millions):
		Useful Life (In Years)		3-Jan-15				December 28,
								2013
	Land and Improvements			$	68.8			$	72.3
	Buildings and Improvements	Mar-50		235.4				231.1
	Machinery and Equipment	15-Mar		812.1				794.5
	Property, Plant and Equipment			1,116.30				1,097.90
	Less: Accumulated Depreciation			(584.8		)		(524.5		)
	Net Property, Plant and Equipment			$	531.5			$	573.4
	Commitments for property, plant and equipment purchases were $10.6 million at January 3, 2015.
	Goodwill
	The Company evaluates the carrying amount of goodwill annually or more frequently if events or circumstances indicate that an asset might be impaired. Factors that could trigger an impairment review include significant underperformance relative to historical or forecasted operating results, a significant decrease in the market value of an asset or significant negative industry or economic trends. The Company performs the required annual goodwill impairment test as of the end of the October fiscal month.
	The Company uses a weighting of the market approach and the income approach (discounted cash flow method) in testing goodwill for impairment. In the market approach, the Company applies performance multiples from comparable public companies, adjusted for relative risk, profitability, and growth considerations, to the reporting units to estimate fair value. The key assumptions used in the discounted cash flow method used to estimate fair value include discount rates, revenue growth rates, terminal growth rates and cash flow projections. Discount rates, growth rates and cash flow projections are the most sensitive and susceptible to change as they require significant management judgment. Discount rates are determined by using a weighted average cost of capital (“WACC”). The WACC considers market and industry data as well as Company-specific risk factors for each reporting unit in determining the appropriate discount rate to be used. The discount rate utilized for each reporting unit is indicative of the return an investor would expect to receive for investing in such a business. Terminal growth rate determination follows common methodology of capturing the present value of perpetual cash flow estimates beyond the last projected period assuming a constant WACC and long-term growth rates.
	The calculated fair values for the Company's 2014 impairment testing exceeded the carrying values of the reporting units for a majority of the Company's reporting units. There were certain reporting units where the calculated fair values were less than the carrying values. The Commercial and Industrial Systems segment and the Power Transmission Solutions segment include reporting units that have significant exposure to the volatility in the oil and gas industry. Crude oil prices saw a sharp decline in the latter part of 2014. Expected cash flows were also negatively impacted by lower gas and oil prices as lower prices decreased the capital spending of customers these reporting units serve. Weak economic conditions in regions such as Australia and New Zealand as well as currency devaluations in Venezuela have contributed to the reduced expected cash flows for the Company's reporting units in these regions. In the Climate Solutions segment, unfavorable customer dynamics impacted one reporting unit's expected cash flows. An implied goodwill amount was then calculated as a required second step in the testing, using the estimated fair value of all assets and liabilities of the reporting unit as if the unit had been acquired in a business combination. The resulting implied fair value of goodwill is a Level 3 asset measured at fair value on a non-recurring basis (see also Note 14 of the Notes to the Consolidated Financial Statements for fair value definitions). Additionally, the Company's reporting unit related to technology that had been deemed substantially impaired during the fourth quarter of 2013 was deemed fully impaired during 2014 as a result of the closing of the facility. This resulted in a $1.0 million impairment charge to goodwill. The total goodwill impairment charge related to these reporting units was $119.5 million and was recorded in Goodwill Impairment within the Consolidated Statements of Income.
	The calculated fair values for the Company's 2013 impairment testing exceeded the carrying values of the reporting units for a majority of the Company's reporting units. There were certain reporting units where the calculated fair values were less than the carrying values. Reporting units within the Commercial and Industrial Systems and Climate Solutions segments experienced declines in sales and profitability that were more pronounced in the latter part of fiscal 2013, combined with reduced expected cash flow from weak economic conditions in regions such as Australia, India and Europe. Another reporting unit had reduced future cash flows from a slower than expected adoption of switched reluctance motor technology. In the Power Transmission Solutions segment, a reporting unit's expected cash flows were reduced by weak sales for the hydraulic fracturing market within the oil and gas industry. An implied goodwill amount was then calculated as a required second step in the testing, using the estimated fair value of all assets and liabilities of the reporting unit as if the unit had been acquired in a business combination. The resulting implied fair value of goodwill is a Level 3 asset measured at fair value on a non-recurring basis. The total goodwill impairment charge related to these reporting units was $76.3 million and was recorded in Goodwill Impairment.
	In the Consolidated Statement of Income for the twelve months ended December 28, 2013, $76.3 million that had been previously reported within "Asset Impairments and Other, Net" is separately reported as "Goodwill Impairment" within the Consolidated Statements of Income.
	Long-Lived Assets
	The Company evaluates the recoverability of the carrying amount of intangible assets whenever events or changes in circumstance indicate that the carrying amount of an asset may not be fully recoverable through future cash flows. Factors that could trigger an impairment review include a significant decrease in the market value of an asset or significant negative or economic trends. For definite-lived intangible assets, the Company uses an estimate of the related undiscounted cash flows over the remaining life of the primary asset to estimate recoverability. If the asset is not recoverable, the asset is written down to fair value.
	During 2014, due primarily to unfavorable customer dynamics and the effects of the sharp decline in the price of oil, the carrying amounts of intangible and other long-lived assets for two reporting units within the Climate Solutions and Power Transmission Solutions segments were deemed to be not fully recoverable. Fair value was determined using the discounted cash flows from the Company's internal cash flow projections and a discount rate indicative of the return an investor would expect to receive for investing in the asset which are Level 3 measurements. As a result, intangible and other long-lived asset impairments of $26.2 million were recognized related to hydraulic fracturing equipment used in the oil and gas end markets. Technology and other long-lived asset impairments were recognized related to products used in hermetic climate applications of $13.8 million and recognized in Asset Impairments and Other, Net.
	During 2013, indicators related to the future expected cash flows of certain reporting units in the Commercial and Industrial Systems segment triggered a detailed undiscounted cash flow test of long-lived assets, which included intangible assets. Discounted cash flows were determined as discussed above, which are Level 3 measurments. As a result, in-process research and development technology intangible impairments totaling $16.2 million, related to switched reluctance technology, and $0.8 million of customer relationship intangible impairments related to a European motor distribution reporting unit were impaired and recognized in Asset Impairments and Other, Net.
	The Company does not have any indefinite-lived intangible assets.
	During the year ended December 28, 2013, the Company recognized a loss on certain intangible asset impairments as discussed above, which was netted with a related gain of $12.3 million from a fair value adjustment for a contingent consideration liability related to one of the reporting units (see Note 14 of Notes to the Consolidated Financial Statements).

Earnings per Share (“EPS”)
Diluted earnings per share is computed based upon earnings applicable to common shares divided by the weighted-average number of common shares outstanding during the period adjusted for the effect of other dilutive securities. Options for common shares where the exercise price was above the market price have been excluded from the calculation of effect of dilutive securities shown below; the amount of these shares were 0.3 million in 2014, 0.7 million in 2013 and 0.3 million in 2012. The following table reconciles the basic and diluted shares used in EPS calculations for the years ended (in millions):
	2014			2013			2012
Denominator for Basic EPS	45			45			41.8
Effect of Dilutive Securities	0.3			0.4			0.3
Denominator for Diluted EPS	45.3			45.4			42.1
Retirement Plans
The Company's domestic employees are covered by defined contribution plans and approximately half of the Company's employees are covered by defined benefit plans. The defined benefit pension plans have been closed to new employees and frozen for existing employees. Most of the Company's foreign employees are covered by government sponsored plans in the countries in which they are employed. The Company's obligations under its defined benefit pension plans are determined with the assistance of actuarial firms. The actuaries, under management's direction, make certain assumptions regarding such factors as withdrawal rates and mortality rates. The actuaries also provide information and recommendations from which management makes further assumptions on such factors as the long-term expected rate of return on plan assets, the discount rate on benefit obligations and where applicable, the rate of annual compensation increases.
Based upon the assumptions made, the investments made by the plans, overall conditions and movement in financial markets, life-spans of benefit recipients and other factors, annual expenses and recorded assets or liabilities of these defined benefit pension plans may change significantly from year to year.
Derivative Financial Instruments
Derivative instruments are recorded on the Consolidated Balance Sheet at fair value. Any fair value changes are recorded in Net Earnings or Accumulated Other Comprehensive Loss as determined under accounting guidance that establishes criteria for designation and effectiveness of the hedging relationships.
The Company uses derivative instruments to manage its exposure to fluctuations in certain raw material commodity pricing, fluctuations in the cost of forecasted foreign currency transactions, and variability in interest rate exposure on floating rate borrowings. The majority of derivative instruments have been designated as cash flow hedges (see also Note 13 of Notes to the Consolidated Financial Statements).
Income Taxes
The Company operates in numerous taxing jurisdictions and is subject to regular examinations by various U.S. Federal, state and foreign jurisdictions for various tax periods. Its income tax positions are based on research and interpretations of the income tax laws and rulings in each of the jurisdictions in which it does business. Due to the subjectivity of interpretations of laws and rulings in each jurisdiction, the differences and interplay in tax laws between those jurisdictions as well as the inherent uncertainty in estimating the final resolution of complex tax audit matters, estimates of income tax liabilities may differ from actual payments or assessments.
Foreign Currency Translation
For those operations using a functional currency other than the U.S. dollar, assets and liabilities are translated into U.S. dollars at year-end exchange rates, and revenues and expenses are translated at weighted-average exchange rates. The resulting translation adjustments are recorded as a separate component of shareholders' equity. Pursuant to accounting rules guiding highly inflationary currency, the Company no longer translates its Venezuelan subsidiary's financial statements as its functional currency is the U.S. dollar.
Product Warranty Reserves
The Company maintains reserves for product warranty to cover the stated warranty periods for its products. Such reserves are established based on an evaluation of historical warranty experience and specific significant warranty matters when they become known and can reasonably be estimated.
Accumulated Other Comprehensive Loss
Foreign currency translation adjustments, unrealized gains and losses on derivative instruments designated as hedges and pension liability adjustments are included in shareholders' equity under accumulated other comprehensive loss.
The components of the ending balances of Accumulated Other Comprehensive Loss are as follows (in millions):
	2014				2013
Foreign Currency Translation Adjustments	$	(80.5	)		$	(27.0	)
Hedging Activities, net of tax of $(19.0) in 2014 and $(5.9) in 2013	(31.0		)		(9.5		)
Pension and Post Retirement Benefits, net of tax of $(23.4) in 2014 and $(14.3) in 2013	(39.5		)		(23.3		)
Total	$	(151.0	)		$	(59.8	)
Legal Claims
The Company records expenses and liabilities when the Company believes that an obligation of the Company or a subsidiary on a specific matter is probable and there is a basis to reasonably estimate the value of the obligation. This methodology is used for legal claims that are filed against the Company or a subsidiary from time to time. The uncertainty that is associated with such matters frequently requires adjustments to the liabilities previously recorded.
Fair Values of Financial Instruments
The fair values of cash equivalents, term deposits, trade receivables and accounts payable approximate the carrying values due to the short period of time to maturity. The fair value of long-term debt is estimated using discounted cash flows based on rates for instruments with comparable maturities and credit ratings. The fair value of pension assets, derivative instruments and contingent purchase price obligations is determined based on the methods disclosed in Notes 8 and 14 of Notes to the Consolidated Financial Statements.
Recent Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board ("FASB") issued Revenue from Contracts with Customers (Accounting Standard Update ("ASU") 2014-09), a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance under U.S. GAAP. This update requires the Company to recognize revenue at amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods or services at the time of transfer. In doing so, the Company will need to use more judgment and make more estimates than under today’s guidance. Such estimates include identifying performance obligations in the contracts, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The Company can either apply a full retrospective adoption or a modified retrospective adoption. The Company is required to adopt the new requirements in the first quarter of 2017. The Company is currently evaluating the impact of the new requirements to its consolidated financial statements.
In April 2014, the FASB issued ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which amends the definition of a discontinued operation and requires entities to provide additional disclosures about disposal transactions that do not meet the discontinued-operations criteria. Under the new guidance, a discontinued operation may include a component or group of components of an entity that has been disposed of by sale or other than sale in accordance with applicable guidance, or is classified as held for sale, and “represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results.” The new guidance also requires entities to provide certain disclosures about disposals that do not meet the criteria to be reported as a discontinued operation but are considered individually significant components.
This ASU is effective prospectively for all disposals (except disposals classified as held for sale before the adoption date) or components initially classified as held for sale in periods beginning on or after December 15, 2014, with early adoption permitted. The Company has elected to early adopt ASU 2014-08, effective June 29, 2014. Consequently, individually significant operations that are sold or classified as held for sale may not qualify for presentation as discontinued operations in the consolidated financial statements, but will be disclosed in the notes to the consolidated financial statements. (See also Note 4 to the Consolidated Financial Statements.) This ASU did not have a significant impact on the Company's financial position, results of operations or cash flows for any of the periods presented.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill And Intangible Assets	Goodwill and Intangible Assets
	Goodwill
	As described in Note 4 of Notes to the Consolidated Financial Statements, the Company acquired two businesses in 2014 and two businesses in 2013. The excess of purchase price over estimated fair value was assigned to goodwill.
	As described in Note 3 of Notes to the Consolidated Financial Statements, the Company evaluates the carrying amount of goodwill annually or more frequently if events or circumstances indicate that an asset might be impaired. As a result of the annual review, there were certain reporting units where the carrying value, exceeded fair value.
	The Commercial and Industrial Systems segment and the Power Transmission Solutions segment include reporting units that have significant exposure to the volatility in the oil and gas industry. These markets saw a sharp decline in the latter part of 2014, leading to declines in sales and profitability and thereby reducing expected cash flows. Expected cash flows were also negatively impacted by lower gas and oil prices as lower prices decreased the capital spending of customers these reporting units serve. Weak economic conditions in regions such as Australia and New Zealand as well as currency devaluations in Venezuela have contributed to the reduced expected cash flows for the Company's reporting units in these regions. In the Climate Solutions segment, unfavorable customer dynamics impacted one reporting unit's expected cash flows. Additionally, the Company's reporting unit related to technology that had been deemed substantially impaired during the fourth quarter of 2013 was deemed fully impaired during 2014 as a result of the closing of the facility.
	Reporting units within the Commercial and Industrial Systems and Climate Solutions segments experienced declines in sales and profitability that were more pronounced in the latter part of fiscal 2013, combined with reduced future expected cash flows driven by weak sales and margins resulting from economic conditions in Australia, India and Europe. Another reporting unit had reduced future expected cash flows from a slower than expected adoption of switched reluctance motor technology. In the Power Transmission Solutions segment, one reporting unit had reduced expected cash flows resulting from weak sales in the hydraulic fracturing market within the oil and gas industry.
	See Note 3 of Notes to the Consolidated Financial Statements, "Goodwill" and "Long-Lived Assets" for additional details of the impairments.
	The following table presents changes to goodwill during the periods indicated (in millions):
		Total				Commercial and Industrial Systems				Climate Solutions				Power Transmission Solutions

	Intangible Assets
	As described in Note 3 of Notes to the Consolidated Financial Statements, the Company evaluates intangible assets in accordance with prescribed guidance. As a result of this review, during 2014, due primarily to the sharp decline in the price of oil, the carrying amounts of intangible assets for two reporting units within the Climate Solutions and Power Transmission Solutions segments were deemed impaired. The impairment charges related to these two reporting units were $7.8 million and $11.1 million, respectively. During fiscal 2013, a total of $17.0 million of intangible assets in the Commercial and Industrial Systems segment were deemed impaired. A switched reluctance technology reporting unit recognized a $16.2 million impairment in technology and a motor distribution reporting unit in Europe recognized a $0.8 million impairment in customer relationships.

	In the fourth quarter of 2014, the Company reorganized its reportable segments to align with its new management reporting structure and business activities. Prior to this reorganization, the Company was comprised of two reportable segments for financial reporting purposes: Electrical and Mechanical. As a result of this change, the Company is now comprised of three reportable segments: Commercial & Industrial Systems, Climate Solutions and Power Transmission Solutions. Historical financial information has been revised on a basis consistent with these segments.
	The Climate Solutions segment produces small motors, controls and air moving solutions. Applications include residential and light commercial HVAC, commercial refrigeration and water heaters.
	The Power Transmission Solutions segment produces power transmission gearing, hydraulic pump drives, large open gearing and specialty mechanical products. Applications include material handling, industrial equipment, energy and off-road equipment.
	The Company evaluates performance based on the segment's income from operations. Corporate costs have been allocated to each segment based on the net sales of each segment. The reported external net sales of each segment are from external customers.
	The following sets forth net sales by country in which the Company operates for fiscal 2014, fiscal 2013 and fiscal 2012, respectively (in millions):

Long-term Debt, Unclassified [Abstract]
Debt And Bank Credit Facilities	Debt and Bank Credit Facilities
	The Company's indebtedness as of January 3, 2015 and December 28, 2013 was as follows (in millions):

			633.8		767.4
		Less: Current Maturities	8.4		158.4
		Non-current Portion	$	625.4	$	609
	Senior Notes
	At January 3, 2015, the Company had $600.0 million of senior notes (the “Notes”) outstanding. The Notes consist of (i) $500.0 million in senior notes (the “2011 Notes”) in a private placement which were issued in seven tranches with maturities from seven to twelve years and carry fixed interest rates and (ii) $100.0 million in senior notes (the “2007 Notes”) issued in 2007 with a floating interest rate based on a margin over the London Inter-Bank Offered Rate (“LIBOR”). In August 2014, $150.0 million of the 2007 Notes matured. The Company repaid that tranche of the 2007 Notes at maturity with a combination of cash and borrowings under the Prior Revolving Facility (as that term is defined below).
	Details on the Notes at January 3, 2015 were (in millions):
			Principal		Interest Rate		Maturity
	Floating Rate Series 2007A		100		Floating (1)		1-Aug-17
	Fixed Rate Series 2011A		100		4.10%		1-Jul-18
	Fixed Rate Series 2011A		230		4.8 to 5.0%		1-Jul-21
	Fixed Rate Series 2011A		170		4.9 to 5.1%		1-Jul-23
			$	600
	(1) Interest rates vary as LIBOR varies. At January 3, 2015, the interest rate was 0.9%.
	The Company has interest rate swap agreements to manage fluctuations in cash flows resulting from interest rate risk (see also Note 13 of Notes to the Consolidated Financial Statements).
	Compliance With Financial Covenants
	The Prior Credit Agreement and the Notes require the Company to meet specified financial ratios and to satisfy certain financial condition tests. The Company was in compliance with all financial covenants contained in the Notes and the Prior Credit Agreement as of January 3, 2015.
	The Prior Credit Agreement and Prior Revolving Facility
	On June 30, 2011, the Company entered into a revolving credit agreement (the “Prior Credit Agreement”) that provided for an aggregate amount of availability under a revolving credit facility of $500.0 million, including a $100.0 million letter of credit subfacility (the “Prior Revolving Facility”). The Prior Revolving Facility permitted borrowing at interest rates based upon a margin above LIBOR. At January 3, 2015, the Company had $17.0 million outstanding on the Prior Revolving Facility and at December 28, 2013, there were no outstanding borrowings on the Prior Revolving Facility. The average balance in direct borrowings under the Prior Revolving Facility was $20.3 million and $0.6 million in fiscal 2014 and fiscal 2013, respectively. The average interest rate paid under the Prior Revolving Facility was 1.4% in fiscal 2014 and 1.4% in fiscal 2013. At January 3, 2015, the Company had approximately $27.2 million in standby letters of credit issued and $455.8 million in available borrowings under the Prior Revolving Facility.
	Other Notes Payable
	At January 3, 2015, other notes payable of approximately $16.8 million were outstanding with a weighted average interest rate of 2.5%. At December 28, 2013, other notes payable of approximately $17.4 million were outstanding with a weighted average rate of 2.7%..
	Based on rates for instruments with comparable maturities and credit quality, which are classified as Level 2 inputs (see also Note 14 of Notes to the Consolidated Financial Statements), the approximate fair value of the Company's total debt was $666.8 million and $779.6 million as of January 3, 2015 and December 28, 2013, respectively.
	Maturities of long-term debt are as follows (in millions):
	Year				Amount of Maturity
	2015				$	8.4
	2016				17.5
	2017				103.3
	2018				100.5
	2019				0.5
	Thereafter				403.6
	Total				$	633.8
	The New Credit Agreement
	In connection with the PTS Acquisition, on January 30, 2015, the Company entered into a Credit Agreement (the “Credit Agreement”) with JPMorgan Chase Bank, N.A., as Administrative Agent and the lenders named therein, providing for a (i) 5-year unsecured term loan facility in the principal amount of $1.25 billion (the “Term Facility”) and (ii) a 5-year unsecured multicurrency revolving facility in the principal amount of $500.0 million (the “Multicurrency Revolving Facility”) available for general corporate purposes. The Credit Agreement replaced the Prior Credit Agreement, and the Multicurrency Revolving Facility replaced the Prior Revolving Facility. The Term Facility was drawn in full on January 30, 2015 in connection with the closing of the PTS Acquisition.  The loans under the Term Facility require quarterly amortization at a rate starting at 5.0% per annum, increasing to 7.5% per annum after two years and further increasing to 10.0% per annum for the last two years of the facility.
	The Credit Agreement requires the Company prepay the loans under the Term Facility with 100% of the net cash proceeds received from specified asset sales and incurrences of borrowed money indebtedness, subject to certain exceptions.
	Borrowings under the Credit Agreement bear interest at floating rates based upon indices determined by the currency of the borrowing, plus an applicable margin determined by reference to the Company's consolidated funded debt to consolidated EBITDA ratio or at an alternate base rate.
	The Company will pay a non-use fee on the aggregate unused amount of the Multicurrency Revolving Facility at a rate determined by reference to its consolidated funded debt to consolidated EBITDA ratio.
	The Credit Agreement contains customary affirmative and negative covenants and events of default for an unsecured financing arrangement, including, among other things, limitations on consolidations, mergers and sales of assets.

Pension and Other Postretirement Benefit Expense [Abstract]
Retirement Plans	(8) Retirement Plans
	The Company's domestic employees are participants in defined benefit pension plans and/or defined contribution plans. The majority of the Company's defined benefit pension plans covering the Company's domestic employees have been closed to new employees and frozen for existing employees. Most foreign employees are covered by government sponsored plans in the countries in which they are employed. The domestic employee plans include defined contribution plans and defined benefit pension plans. The defined contribution plans provide for Company contributions based, depending on the plan, upon one or more of participant contributions, service and profits. Company contributions to domestic defined contribution plans totaled $8.8 million, $9.1 million, and $9.8 million in 2014, 2013 and 2012, respectively. Company contributions to non-U.S. defined contribution plans were $12.6 million, $12.4 million and $12.0 million in 2014, 2013, and 2012, respectively.
	Benefits provided under defined benefit pension plans are based, depending on the plan, on employees' average earnings and years of credited service, or a benefit multiplier times years of service. Funding of these qualified defined benefit pension plans is in accordance with federal laws and regulations. The actuarial valuation measurement date for pension plans is as of fiscal year end for all periods.
	The Company's target allocation, target return and actual weighted-average asset allocation by asset category are as follows:
		Target						Actual Allocation
		Allocation			Return			2014			2013
	Equity investments	76	%		6.7 - 8.4 %			71	%		69	%
	Fixed income	19	%		3.7 - 4.4%			24	%		23	%
	Other	5	%		7	%		5	%		8	%
	Total	100	%		7.5	%		100	%		100	%
	The Company's investment strategy for its defined benefit pension plans is to achieve moderately aggressive growth, earning a long-term rate of return sufficient to allow the plans to reach fully funded status. Accordingly, allocation targets have been established to fit this strategy, with a heavier long-term weighting of investments in equity securities. The long-term rate of return assumptions consider historic returns and volatilities adjusted for changes in overall economic conditions that may affect future returns and a weighting of each investment class.
	The following table presents a reconciliation of the funded status of the defined benefit pension plans (in millions):
					2014				2013

	Funded status				$	(67.7	)		$	(42.2	)
	Pension Assets
	The Company classifies the pension plan investments into Level 1, which refers to securities valued using quoted prices from active markets for identical assets, Level 2, which refers to securities not traded on an active market but for which observable market inputs are readily available, and Level 3, which refers to securities valued based on significant unobservable inputs. Common stocks and mutual funds are valued at the unadjusted quoted market prices for the securities. Real estate fund values are determined using model-based techniques that include relative value analysis and discounted cash flow techniques. Common collective trust funds and limited partnership interests are valued based on the net asset value ("NAV") as provided by the administrator of the fund as a practical expedient to estimate fair value.  The NAV is based on the value of the underlying assets owned by the fund, minus its liabilities, and then divided by the number of shares outstanding.  Investments in units of collective trust funds and short-term investment funds, comprised of cash and money market funds, are valued at their respective NAVs as reported by the funds daily.
	Pension assets by type and level are as follows (in millions):

The Level 3 assets noted below represent investments in a real estate fund managed by a major U.S. insurance company and a global emerging markets fund limited partnership. Estimated values provided by fund management approximate the cost of the investments. In determining the reasonableness of the methodology used to value the Level 3 investments, the Company evaluates a variety of factors including reviews of economic conditions, industry and market developments, and overall credit ratings.
The limited partnership interest is an investment in the Vontobel Global Emerging Markets Fund, which seeks to provide capital appreciation by investing in a diversified portfolio consisting primarily of equity based securities. The common collective trust funds are investments in the Northern Trust Collective S&P 500 Index Fund and the Northern Trust Collective Aggregate Bond Index Fund. The Northern Trust Collective S&P 500 Index Fund seeks to provide investment results that approximate the overall performance of the common stocks in that index. The Northern Trust Collective Aggregate Bond Index Fund seeks to provide investment results that approximate the overall performance of the Barclays Capital U.S. Aggregate Index by investing primarily, but not exclusively, in securities that comprise that index. The common collective trust funds are available for immediate redemption.
The real estate fund can be redeemed on a quarterly basis and paid within two weeks of the request for redemption. The limited partnership interest can be redeemed on a monthly basis with immediate payment.
The table below sets forth a summary of changes in the Company's Level 3 assets in its pension plan investments as of January 3, 2015 and December 28, 2013 (in millions).
		January 3,				December 28,

The following table sets forth a summary of quantitative information about the significant unobservable inputs used in the fair value measurement of the Level 3 real estate fund for the year ended January 3, 2015 (in millions).
Fair Value				Significant Unobservable Inputs
$	6.2			Exit Capitalization Rate	5.3% to 7.5%

The following table sets forth a summary of quantitative information about the significant unobservable inputs used in the fair value measurement of the Level 3 real estate fund for the year ended December 28, 2013 (in millions).
Fair Value				Significant Unobservable Inputs
$	5.5			Exit Capitalization Rate	5.4% to 7.6%
				Discount Rate	6.9% to 9.7%
The Company recognized the funded status of its defined benefit pension plans on the balance sheet as follows (in millions):
		2014				2013
Accrued compensation and employee benefits		$	2.7			$	2.5
Pension and other post retirement benefits		65				39.7
		$	67.7			$	42.2
Amounts recognized in Accumulated Other Comprehensive Loss
Net actuarial loss		$	61.5			36
Prior service cost		1.4				1.6
		$	62.9			$	37.6
The accumulated benefit obligation for all defined benefit pension plans was $182.3 million and $160.1 million at January 3, 2015 and December 28, 2013, respectively.
The accumulated plan benefit obligation exceeded plan assets for all pension plans as of January 3, 2015. The projected benefit obligation, accumulated benefit obligation and fair value of plan assets for the Company's pension plans in which the accumulated benefit obligation exceeded the value of plan assets as of December 28, 2013 were $50.4 million, $43.0 million and $9.1 million, respectively.
The following weighted average assumptions were used to determine the projected benefit obligation at January 3, 2015 and December 28, 2013, respectively.
	2014		2013
Discount rate	4.20%		5.00%
Expected long-term rate of return on assets	7.50%		8.00%
The objective of the discount rate assumption is to reflect the rate at which the pension benefits could be effectively settled. In making the determination, the Company takes into account the timing and amount of benefits that would be available under the plans. The methodology for selecting the discount rate was to match the plan's cash flows to that of a theoretical bond portfolio yield curve.
Certain of the Company's defined benefit pension plan obligations are based on years of service rather than on projected compensation percentage increases. For those plans that use compensation increases in the calculation of benefit obligations and net periodic pension cost, the Company used an assumed rate of compensation increase of 3.0% for the years ended January 3, 2015 and December 28, 2013.
Net periodic pension benefit costs and the net actuarial loss and prior service cost recognized in other comprehensive income (“OCI”) for the defined benefit pension plans were as follows (in millions):
		2014				2013				2012
Service cost		$	2.5			$	2.9			$	2.5
Interest cost		8.3				7.6				7.9
Expected return on plan assets		(9.2		)		(8.7		)		(8.0		)
Amortization of net actuarial loss		2.3				4.1				3.6
Amortization of prior service cost		0.2				0.2				0.2
Net periodic benefit cost		$	4.1			$	6.1			$	6.2
Change in benefit obligations recognized in OCI, net of tax
Prior service cost		$	0.1			$	0.1			$	(0.3	)
Net actuarial loss		1.3				2.5				3.6
Total recognized in OCI		$	1.4			$	2.6			$	3.3
The estimated prior service cost and net actuarial loss for the defined benefit pension plans that will be amortized from Accumulated Other Comprehensive Income ("AOCI") into net periodic benefit cost during the 2015 fiscal year are $0.2 million and $4.6 million, respectively.
As permitted under relevant accounting guidance, the amortization of any prior service cost is determined using a straight-line amortization of the cost over the average remaining service period of employees expected to receive benefits under the plans.
The following weighted average assumptions were used to determine net periodic pension cost for fiscal years 2014, 2013 and 2012, respectively.
		2014		2013		2012

Stockholders' Equity Note [Abstract]
Shareholders' Equity	Shareholders' Equity
	Common Stock
	The Company acquired and retired 500,000 shares of its common stock in the third quarter of 2014 at an average cost of $69.94 per share for a total of $35.0 million.
	The Board of Directors has approved a repurchase program of up to 3.0 million common shares of Company stock. Management is authorized to effect purchases from time to time in the open market or through privately negotiated transactions.
	During 2012, the Company sold 3.2 million shares of common stock for general corporate purposes, working capital and the potential funding of acquisitions.
	Share Based Compensation
	The Company recognized approximately $11.9 million, $11.4 million and $9.0 million in share-based compensation expense in 2014, 2013 and 2012, respectively. The Company recognizes compensation expense on grants of share-based compensation awards on a straight-line basis over the vesting period of each award. As of January 3, 2015, total unrecognized compensation cost related to share-based compensation awards was approximately $21.9 million, net of estimated forfeitures, which the Company expects to recognize over a weighted average period of approximately 2.0 years.
	During 2013, the Company's shareholders approved the 2013 Equity Incentive Plan ("2013 Plan"). The 2013 Plan authorizes the issuance of 3.5 million shares of common stock for equity-based awards, and terminates any further grants under prior equity plans. Approximately 3.0 million shares were available for future grant or payment under the 2013 Plan at January 3, 2015.
	Options and Stock Appreciation Rights
	The Company uses several forms of share-based incentive awards, including non-qualified stock options, incentive stock options, and stock appreciation rights (“SAR's”). Options and SAR's generally vest over 5 years and expire 10 years from the grant date. All grants are made at prices equal to the fair market value of the stock on the grant date. The majority of the Company’s annual share-based incentive awards are made in the fiscal second quarter. For both years ended January 3, 2015 and December 28, 2013, expired and canceled shares were immaterial.
	The table below presents share-based compensation activity for the three fiscal years ended 2014, 2013 and 2012 (in millions):
			2014				2013				2012
	Total intrinsic value of share-based incentive awards exercised		$	5.2			$	4			$	11.1
	Cash received from stock option exercises		1.9				1.5				4.2
	Income tax benefit from the exercise of stock options		2				0.8				2.2
	Total fair value of share-based incentive awards vested		5.5				8.5				6.6
	The assumptions used in the Company's Black-Scholes valuation related to grants for options and SAR's were as follows:
		2014				2013				2012
	Per share weighted average fair value of grants	$	28.01			$	23.01			$	22.45
	Risk-free interest rate	2		%		1.1		%		1.3		%
	Expected life (years)	7				7				7
	Expected volatility	37.7		%		38.5		%		37.6		%
	Expected dividend yield	1.2		%		1.2		%		1.2		%
	The average risk-free interest rate is based on U.S. Treasury security rates in effect as of the grant date. The expected dividend yield is based on the projected annual dividend as a percentage of the estimated market value of the Company's common stock as of the grant date. The Company estimated the expected volatility using a weighted average of daily historical volatility of the Company's stock price over the expected term of the award. The Company estimated the expected term using historical data adjusted for the estimated exercise dates of unexercised awards.
	Following is a summary of share-based incentive plan grant activity (options and SAR's) for fiscal 2014.
	Number of Shares Under Options and SAR's	Shares			Weighted Average Exercise Price				Weighted Average Remaining Contractual Term (years)		Aggregate Intrinsic Value (in millions)
	Outstanding at December 28, 2013	1,563,270			$	56.04
	Granted	148,955			75.76
	Exercised	(163,742	)		43.01
	Forfeited	(59,651	)		60.21
	Outstanding at January 3, 2015	1,488,832			59.34				5.8		$	23.9
	Exercisable at January 3, 2015	878,489			53.2				4.4		19.5
	As of January 3, 2015, there was $11.3 million of unrecognized compensation cost related to non-vested options and SAR's that is expected to be recognized as a change to earnings over a weighted average period of 2.9 years.
	The amount of options expected to vest is materially consistent with those outstanding and not yet exercisable.
	Restricted Stock Awards and Restricted Stock Units
	Restricted stock awards ("RSA") and restricted stock units ("RSU") consist of shares or the rights to shares of the Company's stock. The awards are restricted such that they are subject to substantial risk of forfeiture and to restrictions on their sale or other transfer. As defined in the individual grant agreements, acceleration of vesting may occur under a change in control, or death, disability or normal retirement of the grantee.
	Following is a summary of RSA award activity for fiscal 2014:
			Shares			Weighted Average Fair Value at Grant Date				Weighted Average Remaining Contractual Term (years)
	Unvested RSAs at December 28, 2013		40,717			$	66.5			0.8
	Granted		12,144			75.76
	Vested		(28,047	)		67.83
	Forfeited		—			—
	Unvested RSAs January 3, 2015		24,814			$	69.53			0.3
	RSAs vest on either the first (for RSAs granted in 2013 and later) or the third (for RSAs granted prior to 2013) anniversary of the grant date, provided the holder of the shares is continuously employed by or in the service of the Company until the vesting date. Compensation expense recognized related to the RSA's was $1.5 million for fiscal 2014.
	As of January 3, 2015, there was $0.4 million of unrecognized compensation cost related to non-vested RSA's that is expected to be recognized as a charge to earnings over a weighted average period of 0.3 years.
	Following is a summary of RSU award activity for fiscal 2014:
					Shares			Weighted Average Fair Value at Grant Date				Weighted Average Remaining Contractual Term (years)
	Unvested RSUs at December 28, 2013				210,264			$	65.57			1.9
	Granted				89,050			74.77
	Vested				(53,503	)		69.01
	Forfeited				(7,865	)		64.36
	Unvested RSUs at January 3, 2015				237,946			$	68.28			1.8
	RSU shares vest on the third anniversary of the grant date, provided the holder of the shares is continuously employed by the Company until the vesting date. Compensation expense recognized related to the RSU's was $4.4 million for fiscal 2014.
	As of January 3, 2015, there was $9.3 million of unrecognized compensation cost related to non-vested RSU's that is expected to be recognized as a charge to earnings over a weighted average period of 1.8 years.
	Performance Share Units
	Performance share unit ("PSU") awards consist of shares or the rights to shares of the Company's stock which are awarded to employees of the Company. These shares are payable upon the determination that the Company achieved certain established performance targets and can range from 0% to 200% of the targeted payout based on the actual results. PSU's have a performance period of 3 years. As set forth in the individual grant agreements, acceleration of vesting may occur under a change in control, death or disability. There are no voting rights with these instruments until vesting occurs and a share of stock is issued. The PSU awards are valued using a Monte Carlo simulation method as of the grant date.
	Following is a summary of PSU award activity for fiscal 2014:
					Shares			Weighted Average Fair Value at Grant Date				Weighted Average Remaining Contractual Term (years)
	Unvested PSUs at December 28, 2013				35,730			$	56.71			2.4
	Granted				25,310			83.74
	Vested				—			—
	Forfeited				(1,925	)		57.83
	Unvested PSUs January 3, 2015				59,115			$	68.25			2
	Compensation expense for awards granted are recognized based on the targeted payout of 100.0%, net of estimated forfeitures. Compensation expense recognized related to PSUs was $1.0 million for fiscal 2014 and $0.4 million for fiscal 2013. Total unrecognized compensation expense for all PSUs granted as of January 3, 2015 is estimated to be $2.6 million recognized as a charge to earnings over a weighted average period of 2.0 years.

	Unrecognized tax benefits, January 3, 2015					$	5.8
Unrecognized tax benefits as of January 3, 2015 amount to $5.8 million, all of which would impact the effective income tax rate if recognized.
Potential interest and penalties related to unrecognized tax benefits are recorded in income tax expense. During fiscal 2014, 2013 and 2012, the Company recognized approximately $(0.2) million, $0.2 million and $0.1 million in net interest (income) expense, respectively. The Company had approximately $1.1 million, $1.3 million and $1.1 million of accrued interest as of January 3, 2015, December 28, 2013 and December 29, 2012, respectively.
Due to statute expirations, approximately $0.2 million of the unrecognized tax benefits, including accrued interest, could reasonably change in the coming year.
With few exceptions, the Company is no longer subject to U.S. Federal and state/local income tax examinations by tax authorities for years prior to 2010, and the Company is no longer subject to non-U.S. income tax examinations by tax authorities for years prior to 2008.
At January 3, 2015, the Company had approximately $16.6 million of tax effected net operating losses in various jurisdictions with a portion expiring over a period of up to 15 years and the remaining never expiring. At December 28, 2013, the Company had approximately $11.4 million of tax effected net operating losses in various jurisdictions with a portion expiring over a period up to 15 years and the remaining never expiring.
Valuation allowances totaling $10.1 million and $5.9 million as of January 3, 2015 and December 28, 2013, respectively, have been established for deferred income tax assets primarily related to certain subsidiary loss carryforwards that may not be realized. Realization of the net deferred income tax assets is dependent on generating sufficient taxable income prior to their expiration. Although realization is not assured, management believes it is more-likely-than-not that the net deferred income tax assets will be realized. The amount of the net deferred income tax assets considered realizable, however, could change in the near term if future taxable income during the carryforward period fluctuates.
The Company has been granted a tax holiday for some of its Chinese subsidiaries. This tax holiday expires in 2016 and is renewable subject to certain conditions with which the Company expects to comply.

	One of the Company's subsidiaries that it acquired in 2007 is subject to numerous claims filed in various jurisdictions relating to certain sub-fractional motors that were primarily manufactured through 2004 and that were included as components of residential and commercial ventilation units marketed by a third party. These claims generally allege that the ventilation units were the cause of fires. Based on the current facts, the Company does not believe these claims, individually or in the aggregate, will have a material effect on its results of operations, financial condition or cash flows.
	The Company is, from time to time, party to litigation that arises in the normal course of its business operations, including product warranty and liability claims, contract disputes and environmental, asbestos, employment and other litigation matters. The Company's products are used in a variety of industrial, commercial and residential applications that subject the Company to claims that the use of its products is alleged to have resulted in injury or other damage. The Company accrues for exposures in amounts that it believes are adequate, and the Company does not believe that the outcome of any such lawsuit individually or collectively will have a material effect on the Company's financial position, its results of operations or its cash flows.
	The Company recognizes the cost associated with its standard warranty on its products at the time of sale. The amount recognized is based on historical experience. The following is a reconciliation of the changes in accrued warranty costs for 2014 and 2013 (in millions):

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments
	The Company is exposed to certain risks relating to its ongoing business operations. The primary risks managed using derivative instruments are commodity price risk, currency exchange risk, and interest rate risk. Forward contracts on certain commodities are entered into to manage the price risk associated with forecasted purchases of materials used in the Company's manufacturing process. Forward contracts on certain currencies are entered into to manage forecasted cash flows in certain foreign currencies. Interest rate swaps are entered into to manage interest rate risk associated with the Company's floating rate borrowings.
	The Company is exposed to credit losses in the event of non-performance by the counterparties to various financial agreements, including its commodity hedging transactions, foreign currency exchange contracts and interest rate swap agreements. Exposure to counterparty credit risk is managed by limiting counterparties to major international banks and financial institutions meeting established credit guidelines and continually monitoring their compliance with the credit guidelines. The Company does not obtain collateral or other security to support financial instruments subject to credit risk. The Company does not anticipate non-performance by its counterparties, but cannot provide assurances.
	The Company recognizes all derivative instruments as either assets or liabilities at fair value in the statement of financial position. The Company designates commodity forward contracts as cash flow hedges of forecasted purchases of commodities, currency forward contracts as cash flow hedges of forecasted foreign currency cash flows and interest rate swaps as cash flow hedges of forecasted LIBOR-based interest payments. There were no significant collateral deposits on derivative financial instruments as of January 3, 2015.
	For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of accumulated other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or changes in market value of derivatives not designated as hedges are recognized in current earnings. At January 3, 2015 and December 28, 2013 the Company had $(2.2) million and $(0.7) million, net of tax, of derivative (losses) gains on closed hedge instruments in AOCI that will be realized in earnings when the hedged items impact earnings.

The net AOCI balance related to hedging activities of $(31.0) million losses at January 3, 2015 includes $(19.2) million of net current deferred losses expected to be reclassified to the Statement of Income in the next twelve months. There were no gains or losses reclassified from AOCI to earnings based on the probability that the forecasted transaction would not occur.
The Company's commodity and currency derivative contracts are subject to master netting agreements with the respective counterparties which allow the Company to net settle transactions with a single net amount payable by one party to another party. The Company has elected to present the derivative assets and derivative liabilities on the Consolidated Balance Sheets on a gross basis for the periods ended January 3, 2015 and December 28, 2013.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The inputs used to measure fair value are classified into the following hierarchy:
	Level 1	Unadjusted quoted prices in active markets for identical assets or liabilities
	Level 2	Unadjusted quoted prices in active markets for similar assets or liabilities, or
		Unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or
		Inputs other than quoted prices that are observable for the asset or liability
	Level 3	Unobservable inputs for the asset or liability
	The Company uses the best available information in measuring fair value. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following table sets forth the Company's financial assets and liabilities that were accounted for at fair value on a recurring basis as of January 3, 2015 and December 28, 2013, respectively (in millions):

	Other noncurrent liabilities:
	Deferred contingent purchase price	—				1.4				Level 3
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between participants at the measurement date.
	Level 1 fair value measurements are unadjusted quoted prices.
	Level 2 fair value measurements for derivative assets and liabilities are measured using quoted prices in active markets for similar assets and liabilities. Interest rate swaps are valued based on the discounted cash flows for the LIBOR forward yield curve for a a swap with similar contractual terms. Foreign currency forwards are valued based on exchange rates quoted by domestic and foreign banks for similar instruments. Fair value of debt was estimated based on rates for instruments with comparable maturities and credit quality. The carrying value of debt includes adjustments related to fair value hedges (see Note 7 of Notes to the Consolidated Financial Statements for the fair value estimate of debt).
	Level 3 liabilities are comprised entirely of the deferred contingent purchase price of the Company's acquisitions. The fair value was determined using valuation techniques based on risk and probability adjusted discounted cash flows.
	The Company did not change its valuation techniques during fiscal 2014.
	The table below sets forth a summary of changes in fair value of the Company's liabilities for deferred contingent purchase price from the Company's acquisitions as of January 3, 2015 and December 28, 2013, respectively (in millions):
				Year Ended
				3-Jan-15				28-Dec-13
	Beginning balance			$	9.7			$	21.1
	Expense			—				1.1
	Fair value adjustment			(1.1		)		(12.3		)
	Payments			(8.6		)		(0.2		)
	Ending balance			$	—			$	9.7
	During 2013, the Commercial and Industrial Systems segment reporting unit with slower than expected adoption of switched reluctance motor technology had a deferred contingent purchase price liability that was adjusted as a result of changes in future performance expectations that reduced discounted cash flows and increased risk and probability adjustments. This resulted in a $12.3 million decrease in the deferred contingent purchase price liability in 2013.

Subsequent Events [Abstract]
Subsequent Event	Subsequent Event
	On January 30, 2015, the Company acquired PTS for approximately $1.4 billion in cash. PTS will be included in the Power Transmission Solutions segment. The Company acquired PTS because management believes it provides complementary products, expands and balances the Company’s product portfolio, and enhances its margin profile.
	PTS is a global leader in highly engineered power transmission products and solutions. The business manufactures, sells and services bearings, couplings, gearing, drive components and conveyor systems.
	PTS had net sales of $607.3 million in 2014.
	The following summarizes the allocation of the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition. The allocation of the purchase price is preliminary and differences between the preliminary and final purchase price allocation could be material. The Company has not completed its analysis estimating the fair value of inventory, property, plant, and equipment, intangible assets, income tax liabilities and certain contingent liabilities (in millions).

Accounting Policies [Abstract]
Principles Of Consolidation	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly owned and majority-owned subsidiaries. In addition, the Company has joint ventures that are consolidated in accordance with consolidation accounting guidance. All intercompany accounts and transactions are eliminated.
Use Of Estimates	Use of Estimates
	The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”), which require the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and revenues and expenses during the periods reported. Actual results could differ from those estimates. The Company uses estimates in accounting for, among other items, allowance for doubtful accounts; excess and obsolete inventory; share-based compensation; acquisitions; product warranty obligations; pension assets and liabilities; derivative fair values; goodwill and other asset impairments; health care reserves; retirement benefits; rebates and incentives; litigation claims and contingencies, including environmental matters; and income taxes. The Company accounts for changes to estimates and assumptions when warranted by factually based experience.
Business Combinations Policy [Policy Text Block]	Acquisitions
	The Company recognizes assets acquired, liabilities assumed, contractual contingencies and contingent consideration at their fair value on the acquisition date. The operating results of the acquired companies are included in the Company’s consolidated financial statements from the date of acquisition.
	Acquisition-related costs are expensed as incurred, restructuring costs are recognized as post-acquisition expense and changes in deferred tax asset valuation allowances and income tax uncertainties after the measurement period are recorded in income tax expense.
Revenue Recognition	Revenue Recognition
	The Company generally recognizes revenue upon transfer of title, which generally occurs upon shipment of the product to the customer. The pricing of products sold is generally supported by customer purchase orders, and accounts receivable collection is reasonably assured at the time of shipment. Estimated discounts and rebates are recorded as a reduction of gross sales in the same period revenue is recognized. Product returns and credits are estimated and recorded at the time of shipment based upon historical experience. Shipping and handling costs are recorded as revenue when billed to the customers. The costs incurred from shipping and handling are recorded in Cost of Sales.
	The Company has certain operating leases in the oil and gas industry where revenue is recognized over the term of the lease. The lease revenue is not material for all fiscal periods presented. The related net leased assets were not material at January 3, 2015 and December 28, 2013 and were included in Other Noncurrent Assets.
	The Company derives a significant portion of its revenues from several original equipment manufacturing customers. Despite this relative concentration, there were no customers that accounted for more than 10% of consolidated net sales in fiscal 2014, fiscal 2013 or fiscal 2012.
Research And Development	Research and Development
	The Company performs research and development activities relating to new product development and the improvement of current products. The Company's research and development expenses consist primarily of costs for: (i) salaries and related personnel expenses; (ii) the design and development of new energy efficiency products and enhancements; (iii) quality assurance and testing; and (iv) other related overhead. The Company's research and development efforts tend to be targeted toward developing new products that would allow it to gain additional market share, whether in new or existing segments. While these costs make up an insignificant portion of operating expenses in the Power Transmission Solutions segment, they are more substantial in the Climate Solutions and Commercial and Industrial Systems segments. In particular, a large driver of research and development efforts in the Climate Solutions and Commercial and Industrial Systems segments is energy efficiency.
	Research and development costs are expensed as incurred. For fiscal 2014, 2013 and 2012, research and development costs were $32.9 million, $28.3 million and $28.5 million, respectively. Research and development costs are recorded in Operating Expenses.
Cash And Cash Equivalents	Cash and Cash Equivalents
	Cash equivalents consist of highly liquid investments which are readily convertible to cash, present insignificant risk of changes in value due to interest rate fluctuations and have original or purchased maturities of three months or less.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentration of Credit Risk
	Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash equivalents. The Company has material deposits with a global financial institution. It performs periodic evaluations of the relative credit standing of its financial institutions and monitors the amount of exposure.
	Concentration of credit risk with respect to trade accounts receivable is limited due to the large number of customers and their dispersion across many geographic areas. The Company monitors credit risk associated with its trade receivables.
Investments	Investments
	Investments include term deposits which have original maturities of greater than three months and remaining maturities of less than one year. The fair value of term deposits approximates their carrying value. These investments are included in Prepaid Expenses and Other Current Assets on the Company's Consolidated Balance Sheets.
Trade Receivables	Trade Receivables
	Trade receivables are stated at estimated net realizable value. Trade receivables are comprised of balances due from customers, net of estimated allowances. In estimating losses inherent in trade receivables the Company uses historical loss experiences and applies them to a related aging analysis. Determination of the proper level of allowances requires management to exercise significant judgment about the timing, frequency and severity of losses. The allowances for doubtful accounts take into consideration numerous quantitative and qualitative factors, including historical loss experience, collection experience, delinquency trends and economic conditions.
	In circumstances where the Company is aware of a specific customer's inability to meet its obligation, a specific reserve is recorded against amounts receivable to reduce the net recognized receivable to the amount reasonably expected to be collected. Additions to the allowances for doubtful accounts are maintained through adjustments to the provision for doubtful accounts, which are charged to current period earnings; amounts determined to be uncollectable are charged directly against the allowances, while amounts recovered on previously charged-off accounts benefit current period earnings.
Inventory, Policy [Policy Text Block]	Inventories
	At the beginning of fiscal 2013, the Company changed its inventory valuation method for the finished goods of recently acquired North American businesses to the last-in, first-out ("LIFO") method from the first-in, first-out ("FIFO") method. The Company believes the change to the LIFO method is preferable because it will improve matching of current costs with revenues when there is volatility in the cost of raw materials, and is consistent with the method used for the majority of the Company’s other North American finished goods inventory. Prior period consolidated financial statements have not been retroactively adjusted. The cumulative effect of this change was immaterial.
	The approximate percentage distribution between major classes of inventory at year end is as follows:
		January 3,			December 28,
		2015			2013
	Raw Material and Work In Process	45	%		41	%
	Finished Goods and Purchased Parts	55	%		59	%
	Inventories are stated at cost, which is not in excess of market. Cost for approximately 52% of the Company's inventory at January 3, 2015 and 49% at December 28, 2013 was determined using the LIFO method. If all inventories were valued on the FIFO method, they would have increased by $47.2 million and $58.2 million as of January 3, 2015 and December 28, 2013, respectively. Material, labor and factory overhead costs are included in the inventories.
	The Company reviews inventories for excess and obsolete products or components. Based on an analysis of historical usage and management's evaluation of estimated future demand, market conditions and alternative uses for possible excess or obsolete parts, the Company records inventories at the lower of cost or market.
Property Plant and Equipment Policy Text Block	Property, Plant and Equipment
	Property, Plant and Equipment are stated at cost. Depreciation of plant and equipment is provided principally on a straight-line basis over the estimated useful lives (3 to 50 years) of the depreciable assets. Accelerated methods are used for income tax purposes.
	Expenditures for repairs and maintenance are charged to expense when incurred. Expenditures which extend the useful lives of existing equipment are capitalized and depreciated.
	Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized. Leasehold improvements are capitalized and amortized over the lesser of the life of the lease or the estimated useful life of the asset.
	The Company evaluates property, plant and equipment whenever events or circumstances have occurred that may indicate that carrying values may not be recoverable. If an indicator is present, the Company evaluates carrying values as compared to undiscounted estimated future cash flows. If such estimated future cash flows are less than carrying value, an impairment would be recognized. See also "Long-Lived Assets" in this footnote for the results and additional details of the impairment of certain long-lived assets and related charges.
	Property, plant and equipment by major classification was as follows (in millions):
		Useful Life (In Years)		3-Jan-15				December 28,
								2013
	Land and Improvements			$	68.8			$	72.3
	Buildings and Improvements	Mar-50		235.4				231.1
	Machinery and Equipment	15-Mar		812.1				794.5
	Property, Plant and Equipment			1,116.30				1,097.90
	Less: Accumulated Depreciation			(584.8		)		(524.5		)
	Net Property, Plant and Equipment			$	531.5			$	573.4
	Commitments for property, plant and equipment purchases were $10.6 million at January 3, 2015.
Goodwill And Intangible Assets	Goodwill
	The Company evaluates the carrying amount of goodwill annually or more frequently if events or circumstances indicate that an asset might be impaired. Factors that could trigger an impairment review include significant underperformance relative to historical or forecasted operating results, a significant decrease in the market value of an asset or significant negative industry or economic trends. The Company performs the required annual goodwill impairment test as of the end of the October fiscal month.
	The Company uses a weighting of the market approach and the income approach (discounted cash flow method) in testing goodwill for impairment. In the market approach, the Company applies performance multiples from comparable public companies, adjusted for relative risk, profitability, and growth considerations, to the reporting units to estimate fair value. The key assumptions used in the discounted cash flow method used to estimate fair value include discount rates, revenue growth rates, terminal growth rates and cash flow projections. Discount rates, growth rates and cash flow projections are the most sensitive and susceptible to change as they require significant management judgment. Discount rates are determined by using a weighted average cost of capital (“WACC”). The WACC considers market and industry data as well as Company-specific risk factors for each reporting unit in determining the appropriate discount rate to be used. The discount rate utilized for each reporting unit is indicative of the return an investor would expect to receive for investing in such a business. Terminal growth rate determination follows common methodology of capturing the present value of perpetual cash flow estimates beyond the last projected period assuming a constant WACC and long-term growth rates.
	The calculated fair values for the Company's 2014 impairment testing exceeded the carrying values of the reporting units for a majority of the Company's reporting units. There were certain reporting units where the calculated fair values were less than the carrying values. The Commercial and Industrial Systems segment and the Power Transmission Solutions segment include reporting units that have significant exposure to the volatility in the oil and gas industry. Crude oil prices saw a sharp decline in the latter part of 2014. Expected cash flows were also negatively impacted by lower gas and oil prices as lower prices decreased the capital spending of customers these reporting units serve. Weak economic conditions in regions such as Australia and New Zealand as well as currency devaluations in Venezuela have contributed to the reduced expected cash flows for the Company's reporting units in these regions. In the Climate Solutions segment, unfavorable customer dynamics impacted one reporting unit's expected cash flows. An implied goodwill amount was then calculated as a required second step in the testing, using the estimated fair value of all assets and liabilities of the reporting unit as if the unit had been acquired in a business combination. The resulting implied fair value of goodwill is a Level 3 asset measured at fair value on a non-recurring basis (see also Note 14 of the Notes to the Consolidated Financial Statements for fair value definitions). Additionally, the Company's reporting unit related to technology that had been deemed substantially impaired during the fourth quarter of 2013 was deemed fully impaired during 2014 as a result of the closing of the facility. This resulted in a $1.0 million impairment charge to goodwill. The total goodwill impairment charge related to these reporting units was $119.5 million and was recorded in Goodwill Impairment within the Consolidated Statements of Income.
	The calculated fair values for the Company's 2013 impairment testing exceeded the carrying values of the reporting units for a majority of the Company's reporting units. There were certain reporting units where the calculated fair values were less than the carrying values. Reporting units within the Commercial and Industrial Systems and Climate Solutions segments experienced declines in sales and profitability that were more pronounced in the latter part of fiscal 2013, combined with reduced expected cash flow from weak economic conditions in regions such as Australia, India and Europe. Another reporting unit had reduced future cash flows from a slower than expected adoption of switched reluctance motor technology. In the Power Transmission Solutions segment, a reporting unit's expected cash flows were reduced by weak sales for the hydraulic fracturing market within the oil and gas industry. An implied goodwill amount was then calculated as a required second step in the testing, using the estimated fair value of all assets and liabilities of the reporting unit as if the unit had been acquired in a business combination. The resulting implied fair value of goodwill is a Level 3 asset measured at fair value on a non-recurring basis. The total goodwill impairment charge related to these reporting units was $76.3 million and was recorded in Goodwill Impairment.
	In the Consolidated Statement of Income for the twelve months ended December 28, 2013, $76.3 million that had been previously reported within "Asset Impairments and Other, Net" is separately reported as "Goodwill Impairment" within the Consolidated Statements of Income.
	Long-Lived Assets
	The Company evaluates the recoverability of the carrying amount of intangible assets whenever events or changes in circumstance indicate that the carrying amount of an asset may not be fully recoverable through future cash flows. Factors that could trigger an impairment review include a significant decrease in the market value of an asset or significant negative or economic trends. For definite-lived intangible assets, the Company uses an estimate of the related undiscounted cash flows over the remaining life of the primary asset to estimate recoverability. If the asset is not recoverable, the asset is written down to fair value.
	During 2014, due primarily to unfavorable customer dynamics and the effects of the sharp decline in the price of oil, the carrying amounts of intangible and other long-lived assets for two reporting units within the Climate Solutions and Power Transmission Solutions segments were deemed to be not fully recoverable. Fair value was determined using the discounted cash flows from the Company's internal cash flow projections and a discount rate indicative of the return an investor would expect to receive for investing in the asset which are Level 3 measurements. As a result, intangible and other long-lived asset impairments of $26.2 million were recognized related to hydraulic fracturing equipment used in the oil and gas end markets. Technology and other long-lived asset impairments were recognized related to products used in hermetic climate applications of $13.8 million and recognized in Asset Impairments and Other, Net.
	During 2013, indicators related to the future expected cash flows of certain reporting units in the Commercial and Industrial Systems segment triggered a detailed undiscounted cash flow test of long-lived assets, which included intangible assets. Discounted cash flows were determined as discussed above, which are Level 3 measurments. As a result, in-process research and development technology intangible impairments totaling $16.2 million, related to switched reluctance technology, and $0.8 million of customer relationship intangible impairments related to a European motor distribution reporting unit were impaired and recognized in Asset Impairments and Other, Net.
	The Company does not have any indefinite-lived intangible assets.
	During the year ended December 28, 2013, the Company recognized a loss on certain intangible asset impairments as discussed above, which was netted with a related gain of $12.3 million from a fair value adjustment for a contingent consideration liability related to one of the reporting units (see Note 14 of Notes to the Consolidated Financial Statements).

Earnings Per Share (EPS)	Earnings per Share (“EPS”)
	Diluted earnings per share is computed based upon earnings applicable to common shares divided by the weighted-average number of common shares outstanding during the period adjusted for the effect of other dilutive securities. Options for common shares where the exercise price was above the market price have been excluded from the calculation of effect of dilutive securities shown below; the amount of these shares were 0.3 million in 2014, 0.7 million in 2013 and 0.3 million in 2012. The following table reconciles the basic and diluted shares used in EPS calculations for the years ended (in millions):
		2014			2013			2012
	Denominator for Basic EPS	45			45			41.8
	Effect of Dilutive Securities	0.3			0.4			0.3
	Denominator for Diluted EPS	45.3			45.4			42.1
Retirement Plans	Retirement Plans
	The Company's domestic employees are covered by defined contribution plans and approximately half of the Company's employees are covered by defined benefit plans. The defined benefit pension plans have been closed to new employees and frozen for existing employees. Most of the Company's foreign employees are covered by government sponsored plans in the countries in which they are employed. The Company's obligations under its defined benefit pension plans are determined with the assistance of actuarial firms. The actuaries, under management's direction, make certain assumptions regarding such factors as withdrawal rates and mortality rates. The actuaries also provide information and recommendations from which management makes further assumptions on such factors as the long-term expected rate of return on plan assets, the discount rate on benefit obligations and where applicable, the rate of annual compensation increases.
	Based upon the assumptions made, the investments made by the plans, overall conditions and movement in financial markets, life-spans of benefit recipients and other factors, annual expenses and recorded assets or liabilities of these defined benefit pension plans may change significantly from year to year.
Derivative Financial Instruments	Derivative Financial Instruments
	Derivative instruments are recorded on the Consolidated Balance Sheet at fair value. Any fair value changes are recorded in Net Earnings or Accumulated Other Comprehensive Loss as determined under accounting guidance that establishes criteria for designation and effectiveness of the hedging relationships.
	The Company uses derivative instruments to manage its exposure to fluctuations in certain raw material commodity pricing, fluctuations in the cost of forecasted foreign currency transactions, and variability in interest rate exposure on floating rate borrowings. The majority of derivative instruments have been designated as cash flow hedges (see also Note 13 of Notes to the Consolidated Financial Statements).
Income Taxes	Income Taxes
Foreign Currency Translation	Foreign Currency Translation
	For those operations using a functional currency other than the U.S. dollar, assets and liabilities are translated into U.S. dollars at year-end exchange rates, and revenues and expenses are translated at weighted-average exchange rates. The resulting translation adjustments are recorded as a separate component of shareholders' equity.
Product Warranty Reserves	Product Warranty Reserves
	The Company maintains reserves for product warranty to cover the stated warranty periods for its products. Such reserves are established based on an evaluation of historical warranty experience and specific significant warranty matters when they become known and can reasonably be estimated.
Accumulated Other Comprehensive Loss	Accumulated Other Comprehensive Loss
	Foreign currency translation adjustments, unrealized gains and losses on derivative instruments designated as hedges and pension liability adjustments are included in shareholders' equity under accumulated other comprehensive loss.
	The components of the ending balances of Accumulated Other Comprehensive Loss are as follows (in millions):
		2014				2013
	Foreign Currency Translation Adjustments	$	(80.5	)		$	(27.0	)
	Hedging Activities, net of tax of $(19.0) in 2014 and $(5.9) in 2013	(31.0		)		(9.5		)
	Pension and Post Retirement Benefits, net of tax of $(23.4) in 2014 and $(14.3) in 2013	(39.5		)		(23.3		)
	Total	$	(151.0	)		$	(59.8	)
Legal Claims	Legal Claims
	The Company records expenses and liabilities when the Company believes that an obligation of the Company or a subsidiary on a specific matter is probable and there is a basis to reasonably estimate the value of the obligation. This methodology is used for legal claims that are filed against the Company or a subsidiary from time to time. The uncertainty that is associated with such matters frequently requires adjustments to the liabilities previously recorded.
Fair Values	Fair Values of Financial Instruments
	The fair values of cash equivalents, term deposits, trade receivables and accounts payable approximate the carrying values due to the short period of time to maturity. The fair value of long-term debt is estimated using discounted cash flows based on rates for instruments with comparable maturities and credit ratings. The fair value of pension assets, derivative instruments and contingent purchase price obligations is determined based on the methods disclosed in Notes 8 and 14 of Notes to the Consolidated Financial Statements.
