Stacked lamination rotor
7 Nov 23
The invention is a flywheel rotor that includes a number of adjacent laminations, stacked one on top of another, where each of the laminations has the same shape and is rotationally symmetric around a center axis, and where the shape is substantially circular and includes a plurality of protrusions exterior to the circumference, and each of the laminations includes at least one hole for a fastening bolt to pass through.

Stacked Lamination Endplate
6 Jul 23
A stacked lamination endplate for a rotor that includes a number of adjacent laminations, stacked one on top of another, wherein each lamination has an identical shape, the shape having a central region, symmetric about a center axis, and a number of spokes, each spoke emanating radially outward from the central region, where each spoke includes a through-hole at its distal end, and wherein the laminations are stacked one on top of another and aligned, enabling, for each spoke, a bolt to be inserted through a corresponding through-hole of each lamination.

Utility
Motor/Generator With Atmospheric Stator Pressure
6 Oct 22
The invention is a motor/generator that includes a motor/generator housing that encloses a rotor assembly, which rotates a shaft, and a stator assembly that remains stationary, and where the motor/generator is inside a vacuum chamber, which, during normal operation, is evacuated of gas and operates at a lower air pressure than atomospheric air pressure, and a cylindrical vacuum barrier between the rotor assembly and the stator assembly that together with the motor generator housing partitions the motor/generator into an interior rotor volume and an exterior stator volume, enabling the rotor volume and stator volume to operate at different atmospheric pressures.

Utility
Flywheel with bifurcated molecular pump
8 Mar 22
A flywheel device that includes a housing that surrounds a vacuum chamber, a flywheel rotor within the vacuum chamber, which rotates during normal operation of the flywheel, thus agitating residual gasses, an exhaust chamber that receives the exhaust gases from the vacuum chamber, and an annular shaped stationary element, within the vacuum chamber that includes scroll channels where some of the scroll channels have an intake port on an inner diameter of the stationary element and some of the scroll channels have an intake port on an outer diameter of the stationary element, and the scroll channels enable gasses to flow from the vacuum chamber, through the scroll channels, into the exhaust chamber.

Utility
Grease channel for reducing gas permeation into vacuum chambers
10 Aug 21
A flywheel device includes an enclosure, a top plate that fastens to the enclosure, where the top plate includes a first opening, and a cap, where the cap has a top side and a bottom side, which when fastened to the first opening forms a seal between the bottom side and the first opening, the bottom side including an o-ring groove configured to hold an o-ring, a grease channel concentric with the o-ring groove, and an inlet port configured to enable grease to flow into the grease channel.
