Embodiments of the invention provide an electric machine module including a housing. In some embodiments, the housing can include a sleeve member coupled to at least one end cap. The housing can include an inner wall at least partially defining a machine cavity, a coolant sump, and at least one coolant channel positioned between the inner wall and an outer wall of the housing. In some embodiments, the coolant channel can be in fluid communication with the coolant sump. In some embodiments, an electric machine can be positioned in the machine cavity. The electric machine can comprise a stator assembly including stator end turns and a rotor assembly. In some embodiments, a coolant jacket can be at least partially defined by the housing and can be positioned so that to at least partially circumscribe a portion of the stator assembly.
