Abstract
A field control system for a wound rotor synchronous motor-generator used in electrically powered automobiles is capable of optimizing the performance of the motor-generator for all driving conditions. Using a rotary transformer to transmit power across the rotational boundary, it has no wearing parts and is silent. Preferably, the field control system has common elements with the controller which generates the stator currents of the synchronous motor-generator.
