ABSTRACT:
Disclosed herein is an electric machine stator. The electric machine stator includes a tubular body with a plurality of radial slots formed into a perimetrical surface thereof, each of the plurality of slots having a width that varies over at least a portion of a radial depth of the slot such that the slot width is narrower near the perimetrical surface than the slot width further from the perimetrical surface. The stator further includes at least one winding positioned within each of the plurality of slots and at least one of the at least one winding is deformed within the slot such that at least one dimension of the at least one winding is greater than a narrowest slot width dimension thereby retaining the winding within the slot.
