ABSTRACT:
A flux regulated permanent magnet brushless motor has a stator having an inner peripheral bore. A permanent magnet rotor is mounted within the inner peripheral bore. A control winding is supplied to a DC current to regulate flux of the machine. A small AC current is also supplied and an output is sensed to determine a position of the permanent magnet rotor.
