Abstract
Embodiments of the invention provide an electric machine module including a housing. The housing can include an inner surface that defines a machine cavity. In some embodiments, an electric machine can be at least partially positioned within the machine cavity and can include a stator assembly. The stator assembly includes an outer diameter, a stator core, and a stator winding. The stator core can include at least two extended members that can radially extend from axial ends of the stator core. An annular member is coupled to the extended members to define a portion of a coolant jacket. The coolant jacket can be further defined between the annular member, the outer diameter of the stator assembly, and the extended members. The electric machine can be positioned within the housing so that the annular member is immediately adjacent to the inner surface.
