1. An electric motor comprising:

  • a stator being a stationary wound member;

    a rotor being a movable field member, the magnetic field of said rotor interacting with energized windings of said stator, causing said rotor to move relative to said stator;

    a plurality of stator slots, each stator slot having one elongated solid heat spike of thermal conductive material said heat spikes each extended radially inward from the stator adjacent to said windings to at least the midpoint of the stator slot area, each heat spike substantially centered around the midpoint of slot arc along the stator shell, such that said heat spikes are widest when farther away from said rotor and said heat spikes are narrowest when closer to said rotor; and

    support means for maintaining an air gap between said stator and said rotor.
