Abstract
Embodiments of the invention provide an electric machine module including an electric machine with a stator assembly. The stator assembly includes a plurality of stator laminations coupled together and a plurality of conductors positioned through axial slots of the plurality of stator laminations. The electric machine module also includes a coolant channel at least partially defined within the axial slots and a housing. The housing at least partially circumscribes the electric machine and at least partially defines a machine cavity which is in fluid communication with the coolant channel.
