Abstract
Content

In 1938, General Electric began producing a two-phase synchronous induction motor which, at 60 Hz, ran at 75 RPM. The low speed resulted from using a different number of rotors to stator poles or teeth, which made the motor a good bi-directional control motor. This motor was used by Superior Electric Company of Bristol, CT, to run power driven autotransformers used to dim lights in auditoriums and similar applications. General Electric ceased producing this motor in the mid 1950’s due to slow sales.
