  • Publication number: 20210234436
    Abstract: A cooling assembly for an electric machine is disclosed. The cooling assembly may include a generally cylindrical cooling jacket for receiving a shaft, a rotor and a stator. Further, the cooling jacket jacket may be disposed in an electric machine housing. Additionally, the cooling assembly may include at least two first passages in the cooling jacket for circulating a first coolant and at least one second passage in the cooling jacket for circulating a second coolant, the second passage being disposed between the at least two first passages. Further, the cooling assembly may include a third passage on an exterior of the machine housing, the third passage extending through the housing to fluidly connect the at least two first passages and bypass the second passage.

  • Patent number: 11002289
    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.
