Abstract:
1. An electric machine module comprising: a housing at least partially defining a machine cavity, the housing further including at least a portion of a coolant jacket capable of containing a first coolant; a coolant sump being in fluid communication with the machine cavity, the coolant sump capable of containing a second coolant different from the first coolant, and the coolant sump being in thermal communication with the coolant jacket; an electric machine being positioned substantially within the machine cavity and being at least partially enclosed by the housing, the electric machine including a stator assembly comprising stator end turns, a rotor assembly being at least partially circumscribed by a portion of the stator assembly, and a shaft being operatively coupled to the rotor assembly; at least one coolant channel being disposed through a portion of the housing, the coolant channel being in fluid communication with the coolant sump; at least one shaft channel being disposed through a portion of the shaft, the shaft channel being in fluid communication with the coolant channel; and at least one rotor channel being disposed within a portion of the rotor assembly, the rotor channel being in fluid communication with the shaft channel and the machine cavity.
