Abstract

718,631. Automatic speed control systems. KELVIN & HUGHES, Ltd. June 3, 1953 [March 3, 1952], No. 5503/52. Drawings to Specification. Class 38(4) The speed of an induction motor is controlled by providing it with a high impedance rotor winding connected to a centrifugal switch which opens at the desired speed.
