Abstract
A stator includes a stator hub and a plurality of stator teeth extending from the stator hub that define a stator slot having a stator slot base. At least one winding is disposed in the stator slot and the stator also includes a back iron. The winding surrounds the back iron and is held apart from the stator slot base so that a fluid channel is defined between an inner winding portion of the at least one winding so fluid can be passed between the stator slot base and the inner winding portion to cool the inner winding portion.
