A motor is disclosed in which the main stator winding of, for example, a squirrel case inducting 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 stator winding is provided in parallel with the first stator winding and capacitor which second winding serves as the phase winding and causes the motor to operate as a balanced split phase motor having a high efficiency over a broad range of operating points.
