ABSTRACT:
A permanent magnet electric motor including a rotor having an annular arrangement of field magnets for rotation around an axis relative to a stator. An annular FG magnet arrangement affixed to an end of the rotor cooperates with an adjacent FG coil to produce a signal indicative of the rotor speed. A shunt washer of magnetically permeable material is interposed between the field magnet arrangement and the FG magnet arrangement.
