Abstract
A phase shifting network for an inductor motor is provided. The network includes a resistor connected in series with each motor phase coil of a pair of motor phases. The network further includes a capacitor connected between the motor phases. The inventive phase shifting network produces current and voltage waveforms within the motor phase coils that are smoother, more equal, and less subject to harmonic distortion as compared to the waveforms generated by conventional phase shifting networks.
