Abstract
A rotary electric machine includes a stator, a rotor, a plurality of coils and a plurality of spacers. The stator has a stator body and a plurality of stator poles. Each stator pole has a pair of oppositely facing side surfaces. The rotor is positioned within the stator and has a plurality of rotor poles. One coil is disposed about each stator pole. The spacers are disposed between one coil and at least one of an inner circumferential surface of the stator body and the side surfaces of the stator body to define a fluid flow opening between the coil and the stator.
