Abstract
A rotary position sensor assembly includes a ring magnet extending around the outer surface of a rotatable through shaft. A sensor which measures changes in the direction of the magnetic flux generated by the magnet in response to rotation of the shaft and a pair of magnet pole pieces are located opposite and spaced from the magnet. The sensor is located between the pair of pole pieces and the pole pieces conduct the magnetic flux over the sensor and nominalize the strength of the magnetic flux sensed by the sensor over the full range of rotation of the shaft relative to the sensor.
