Abstract: An apparatus for sensing the relative rotational position between a stator (28) and a rotor (32) in a variable reluctance motor (26) includes a transmitting ring (40) mounted to the rotor (32) and having a transmitting coil (46) mounted thereon. A receiving ring (42) is mounted to stator (46) and has a receiving coil (56) mounted thereon. The receiving coil includes three conductor patterns (56a, 56b, 56c) having the same shape, each of said conductor patterns being electrically insulated from each other, and each conductor pattern being offset from adjacent conductor patterns by 120 electrical degrees. A drive signal is coupled to the transmitting coil. The apparatus further includes a controller (76) for monitoring the outputs from the receiving coil patterns and for determining the relative rotation between the rotor and the stator from the monitored outputs. The receiving coil patterns are each arranged in a circumferentially varying square wave pattern.
