Load-Responsive Motor ControllerNew circuit controls voltage applied to a three-phase induction motor in response to magnitude of current, so as to reduce power consumption when the motor is idling or operating at less than full load. Control circuit decreases rms applied voltage to match decreases in motor load over entire torque range. This considerably decreases power consumption in motors operating at a fraction of their rated torques.
