Abstract
An electric machine includes a housing having an outer surface and an inner surface. A stator is fixedly mounted to the inner surface. The stator includes a stator core, and a plurality of windings supported by the stator core. The plurality of windings includes first and second end turn portions. A rotor is rotatably mounted within the housing. An adaptable cooling system is fluidically connected to the housing. The adaptable cooling system includes a first coolant circuit configured to guide coolant in a heat exchange relationship with the stator core, and a second coolant circuit configured to guide coolant in a heat exchange relationship with the at least one end turn portion. At least one flow controller is configured and disposed to selectively adapt coolant delivery through the first and second coolant circuits based on coolant temperature flowing from the stator.
