ABSTRACT:
A torque angle control system for maintaining a predetermined torque angle in a synchronous motor having a speed command conversion circuit (10) for converting a speed command signal to a synchronous motor control signal, correcting the synchronous motor control signal and generating a fundamental signal related to the corrected synchronous motor control signal, position sensors (26) for sensing the rotational position of a rotor of the synchronous motor (20) and a comparator (30) for comparing the fundamental signal to a rotor position signal and outputting a correction signal to the speed command conversion circuit (10) for correcting the synchronous motor control signal to maintain a predetermined torque angle in the synchronous motor (20).
