A motor includes a motor case including a bottomed tubular first case portion and a bottomed tubular second case portion axially opposed to the first case portion, a stator sandwiched between the first and second case portions, and a rotor including a shaft radially opposed to the stator and extending along a central axis.

A motor includes a rotor including a shaft extending along a central axis, a stator radially facing the rotor, a circuit board electrically connected to a coil of the stator, and a motor case accommodating the stator and the circuit board.

A motor includes a rotor and a stator, a substrate electrically connected to the stator, a sheet-metal cover accommodating the stator and the substrate, and a wiring electrically connected to the substrate.

A motor unit includes a motor, a controller that outputs a pulse signal, a driver that supplies a drive current to the motor based on the pulse signal, and a detector that determines an actual rotation number of the motor.

A counter-rotating fan includes a first fan including a first impeller including first blades radially arranged around a predetermined center axis, a first motor that rotates the first impeller around the center axis, and a first case surrounding an outer circumference of the first impeller, and a second fan including a second impeller including second blades radially arranged around the center axis, a second motor that rotates the second impeller around the center axis, and a second case surrounding an outer circumference of the second impeller.

A counter-rotating axial flow fan includes a first fan including a first impeller including first blades radially arranged around a predetermined central axis, a first motor rotating the first impeller around the central axis, and a first case surrounding an outer periphery of the first impeller, and a second fan including a second impeller including second blades radially arranged around the central axis, a second motor rotating the second impeller around the central axis, and a second case surrounding an outer periphery of the second impeller.
