Cooling system for a rotary electric machine

A rotary electric machine (10) includes a stator (11), a rotor (12), a plurality of coils (25), and a plurality of flow enhancement members (70, 71). Each coil has a compound outer surface (31) along major sections thereof with an insulating layer disposed therealong. The compound outer surfaces (31...

Summary:A rotary electric machine (10) includes a stator (11), a rotor (12), a plurality of coils (25), and a plurality of flow enhancement members (70, 71). Each coil has a compound outer surface (31) along major sections thereof with an insulating layer disposed therealong. The compound outer surfaces (31) of each pair of adjacent coils (25) define a channel (55, 56) extending along adjacent major sections of each adjacent pair of coils. One of the flow enhancement members (70, 71) is disposed within each channel (55, 56) between the adjacent major sections of each pair of adjacent coils (25), with each flow enhancement member defining a gap between the compound outer surface (31) of one of the coils and the flow enhancement member through which cooling fluid may flow.
