A cooling system of an electric machine includes a hub, a rotor core, and a thermal interfacial material interposed between respective complementary mating surfaces of the hub and the rotor core for substantially eliminating air gaps therebetween. A method of cooling an electric machine having a rotor core and a hub includes placing a thermal interfacial material onto a heat transfer interface between the rotor core and the hub, whereby the thermal interfacial material reduces contact resistance at the heat transfer interface. A method includes providing a rotor core having a radially inner surface, coating at least one of a radially outer surface of a hub and the radially inner surface of the rotor core with a thermal interfacial material, and inserting the hub into the rotor core, whereby the thermal interfacial material is interposed between the inner surface of the rotor core and the outer surface of the hub. |
