ABSTRACT An electric motor includes a heat spike within the stator slots which extends radially inward from the stator back iron into the slot between the stator teeth. The heat spike, placed within the stator slots, reduces the heat path length and increases the heat transfer areas to the iron. Together, these allow the winding heat to dissipate quicker, and thereby, reduce the hotspot temperature and improve the motor's load rating.
