Electric motor

Abstract:

An electric motor having a rotor having permanent magnets and a first gear arranged on an inner surface of the rotor, a stator having electromagnetic coils wound around sections of the rotor, a shaft arranged to be rotatably supported in the electric motor, the shaft having a second gear arranged on an outer surface of the shaft, and at least one rotary gear member arranged in a space between the first gear and the second gear. A number of the permanent magnets is the same as a number of the electromagnetic coils, and both the permanent magnets and the electromaqnetic coils are evenly spaced apart in a circumferential manner. The rotor further having a plurality of non-magnetic sections positioned between the plurality of permanent magnets to form an outermost layer of the rotor.
