A stator of an electric motor includes a stator core including a rim and a plurality of stator teeth extending from the rim. The plurality of stator teeth define a plurality of tooth gaps between circumferentially adjacent stator teeth. A plurality of stator windings are wrapped along the plurality of stator teeth. The plurality of stator windings include a plurality of core segments extending along the plurality of tooth gaps, and a plurality of end turn segments connecting adjacent core segments. A plurality of non-electrically conductive cooling channels are located in the stator core. The plurality of cooling channels are configured to direct a cooling fluid flow therethrough to cool the plurality of stator windings.
