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.
