A method of manufacturing an electric motor that includes a plurality of structural cooling features is provided, where the electric motor utilizes axial cooling channels integral to the stator teeth, thus allowing direct contact between the circulating coolant and the lamination stack. A coolant manifold assembly, incorporated into the stator between left and right stator portions, provides a means of distributing coolant to the axial cooling channels.

Motor cooling system utilizing axial cooling channels

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.
