  • ELECTRIC MACHINE ROTOR COOLING
    Publication number: 20220181934
    Abstract: A rotor hub assembly includes a rotor hub, a rotor and a cooling sleeve surrounding the rotor hub and located between the rotor hub and the rotor. Coolant flows between the rotor hub and the rotor during spinning of the rotor hub assembly. The cooling sleeve may include channels formed in the inner surface. The rotor hub may include an annular channel in fluid communication with the cooling sleeve channels. The annular channel may include apertures such that the cavities in the rotor hub are in fluid communication with the cooling sleeve. Coolant circulating within the rotor hub enters the annular channel and the channels in the cooling sleeve from centrifugal force caused by spinning of the rotor hub assembly.
