RD-19,746 IMPROVED SHAFT POSITION SENSOR EMPLOYING A WIEGAND-EFFECT DEVICE A Wiegand-effect shaft position sensor is excited by an alternating magnetic field generated by stationary magnets or solenoids interacting with a high-strength, toothed wheel that is fixed to the rotor. A set of three stationary poles are situated proximate to the rotor and are connected together by a yoke. The magnets or solenoids are mounted in the outside poles of the set of three stationary poles. The central stationary pole contains a Wiegand-effect device. In operation, a flux reversal in the Wiegand-effect device occurs at twice the frequency at which the poles of the toothed wheel pass the the stationary poles, resulting in the generation of sharp voltage pulses indicative of rotor position.
