摘要： An electric machine system includes an alternating current (AC) electric machine. The AC machine includes a machine housing having a machine portion and a switch portion. A stator is fixedly mounted in the machine portion of the machine housing and a rotor rotatably mounted relative to the stator. A switch assembly is arranged within the switch portion of the machine housing and electrically connected to the stator. A direct current (DC) power source is electrically connected to the stator through the switch assembly. A cooling system is fluidly connected to the AC electric machine. The cooling system directs a flow of coolant onto the switch assembly in the switch portion of the machine housing, and onto at least one of the stator and the rotor in the machine portion of the machine housing.

摘要： An electric machine including a housing, and a stator mounted within the housing. The stator includes an outer perimetric surface and an inner perimetric surface. A rotor is mounted, at least in part, within the inner perimetric surface of the stator. The rotor is rotatable relative to the stator. A stator sleeve extends about the stator. The stator sleeve includes a first sleeve portion and a second sleeve portion. The first sleeve portion includes a first diametric edge that extends to a second diametric edge, and the second sleeve portion includes a first diametric edge section that extends to a second diametric edge section. The stator sleeve is configured and disposed to establish a coolant cavity about the outer perimetric surface of the stator.
