Synchronous electric motors, rotors, and methods of operation

Abstract

A rotor for a synchronous electric motor comprises a rotor circuit having a first winding field pole NW1, NW2; a second winding field pole SW1, SW2; and an energy storage device C1 configured to be electrically coupled to the first winding field pole and the second winding field pole. A first current flow control device 3 is arranged between the first winding field pole and the energy storage device, and is configured to allow induced AC half period current components of a single direction to pass from the first winding field pole to the energy storage device. A second current flow control device 4 is arranged between the second winding field pole and the energy storage device, the second current flow control device configured to allow induced AC half period current components of a single direction to pass from the second winding field pole to the energy storage device. The first and second winding field poles may each comprise a plurality of winding field poles, where the plurality of winding field poles may be configured to be in series or in parallel, and the plurality of second winding field poles may be configured to be in parallel.
