Abstract: The present disclosure relates to a dual gerotor apparatus. The dual gerotor apparatus comprises a housing configured to provide a first and second hydraulic fluid circuit sharing a single inlet and a single outlet. The dual gerotor apparatus further comprises a gerotor assembly coupling with a rotatable shaft, the gerotor assembly is configured to transfer a hydraulic fluid flowing through the first or second hydraulic fluid circuit from the single inlet to the single outlet. The gerotor comprises a first gerotor pump and a second gerotor pump, the first gerotor pump will be in operation when the rotatable shaft rotates in a first direction, and the second gerotor pump will be in operation when the rotatable shaft rotates in a second direction.

Abstract: A rotary electric machine includes a rotor configured for coupling with a rotary shaft and a stator configured for surrounding the rotor, the stator includes a stator body and stator end windings which extend from axial ends of the stator body. The rotary electric machine further includes a housing configured for receiving the stator and rotor, the housing includes a fluid distributing chamber provided along an inner surface of the housing for being communicated with a plurality of fluid channels so as to distribute the fluid to flow through outer surfaces of the stator body and stator end windings when the stator is inserted into the housing. The present disclosure further relates to a powertrain assembly and an electrified vehicle including the rotary electric machine.
