Abstract
A method of cooling an electric motor is provided utilizing axial cooling channels that are integral to the stator teeth, thus allowing direct contact between the circulating coolant and the lamination stack and providing an efficient means of removing motor assembly heat. Additionally, as the coolant flows out of the cooling channels it impinges on the end windings, thereby providing a secondary means of cooling the motor assembly.
