Abstract: Embodiments of the invention provide an electric machine module. The module can include a housing, which can define a machine cavity. In some embodiments, a coolant jacket can be at least partially positioned within the housing. In some embodiments, a plurality of coolant apertures can be disposed through at least a portion of the housing. A stator assembly can be at least partially disposed within the housing and can include a plurality of coolant channels being in fluid communication with the machine cavity. Each of the coolant channels includes at least one radial subunit and at least one axial subunit. The radial subunits are fluidly coupled to some of the coolant apertures so that the coolant jacket is in fluid communication with the machine cavity via the coolant channels.

Abstract: An electric machine includes an electric machine housing having a first end, a second end, and an interior. A stator is fixedly mounted relative to the electric machine housing. A pump housing is provided at one of the first and second ends. A rotor is rotatably supported relative to the stator. The rotor includes a shaft having a first end that extends to a second end through an uninterrupted intermediate portion having an outer surface. One of the first and second ends extends into the pump housing. At least one vane element projects from the outer surface and is arranged in the pump housing.
