Abstract
A polyphase motor is disclosed in which each coil of the stator winding of, for example, a squirrel cage induction motor, is connected in series with a capacitor so that the capacitor, together with the input voltage, causes the stator core to periodically switch from a nonsaturated to a saturated condition and vice-versa so that the flux density is maintained at a uniform high level. A second set of stator coils may be provided which serves to provide increased starting torque and improve the overall operating characteristics of the motor.
