Abstract
A permanent magnet generator includes a rotor having poles wherein one of poles of the rotor is non-magnetic. A stator has stator windings wound in cooperation with the poles of the rotor. The non-magnetic pole establishes at least one predetermined position of the rotor. A sensing coil is wound on the stator. The sensing coil responds to the non-magnetic pole by providing an electrical signal indicative of the predetermined position of the rotor.
