ABSTRACT:
First and second stationary driving coils are disposed about drive shaft means on which magnetized rotor means are mounted so as to exert on the drive shaft means output torques 90 degrees out of phase with each other. Coupling means connect the drive shaft means to an output shaft so as the combine the output torques. Sinusoidal driving signals for the driving coils are generated by Hall devices or other means synchronized to the drive shaft means.
