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.
Claims8
An electric machine module comprising:
- an electric machine including a stator assembly, the stator assembly including a plurality of stator laminations coupled together and a plurality of conductors positioned through axial slots of the plurality of stator laminations;
- a coolant channel at least partially defined within the axial slots;
- a housing at least partially circumscribing the electric machine and at least partially defining a machine cavity, the coolant channel being in fluid communication with the machine cavity;
- wherein the housing includes a sleeve member with a coolant jacket which substantially circumscribes the stator assembly, the sleeve member including at least one coolant passageway which at least partially fluidly connects the coolant jacket with the coolant channel.
