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 uniformly high level. A control winding is provided to generate magnetic flux in the stator to vary the volt-second capacity of the magnetic material of the stator in accordance with varying line, load or other selected conditions. The current in the control winding can be externally controlled or may be provided by a feedback winding wound on the stator.
