Abstract
The invention is an efficient electric motor which has fixed permanent and electromagnets in the stator with fixed permanent magnets in the rotor. An electronic Pulse Width Modulator (PWM) controller manages the flow of electric power to the electromagnets of the stator. Infrared sensors and Hall sensors provide the controller with the precise location of the rotor thus allowing the controller to provide the maximal electromagnetic forces to provide increased efficiency for the present electric motor. The present inventive motor is useful in an electric automobile or household use.
