Abstract: A rotary electric machine includes a stator having an open slot configuration and a plurality of stator poles with a coil positioned about each stator pole. Each coil has a plurality of electrically conductive wires defining a group of wires and the group of wires is wrapped generally around a stator pole to define a plurality of turns. At least a portion of the group of wires is twisted, and the portion of the group of wires has between approximately 1 and 5 twists per turn. A method of fabricating a stator assembly is also disclosed.

Abstract: A motor driver for driving a motor is disclosed. The motor driver has a first power bus, a first switching device coupled between the first power bus and a first terminal of the motor, a second power bus, a second switching device coupled between the second power bus and a second terminal of the motor, and an integrated braking chopper coupled between the first and second power buses. The integrated braking chopper is configured to dissipate an extra power generated by the motor.

Abstract: A rotary electric machine includes a stator, a rotor, a plurality of coils, and a plurality of flow enhancement members. Each coil has a compound outer surface along major sections thereof with an insulating layer disposed therealong. The compound outer surfaces of each pair of adjacent coils define a channel extending along adjacent major sections of each adjacent pair of coils. One of the flow enhancement members is disposed within each channel between the adjacent major sections of each pair of adjacent coils, with each flow enhancement member defining a gap between the compound outer surface of one of the coils and the flow enhancement member through which cooling fluid may flow.

Abstract: A coil for a rotary electric machine includes a plurality of electrically conductive wires defining a group of wires wrapped to define a plurality of turns. The coil further includes a pair of major sections and a compound outer surface along the pair of major sections. The compound outer surface has a first leg section and a second leg section with the first leg section and the second leg section at an angle to each other. A bonding material is positioned along portions of the pair of major sections to define the compound outer surface.
