Abstract
An electric machine including a stator core having an outer circumferential surface and an axial row of raised projections that extend radially outboard from the outer surface. The raised projections are axially spaced from each other to define circumferential channels therebetween. A housing defines a cavity that receives the stator core. The housing has an inner circumferential surface in contact with the raised projections and radially spaced from the outer surface of the core to define a void space in fluid communication with the channels. The void space and the channels cooperate to form a fluid circuit that overlays the outer circumferential surface such that the fluid is in direct contact with the stator core.
