Abstract

The present invention includes a rotary sensing system that includes a shaft, a magnet encircling the shaft, a pair of plates, each of which is positioned near distal ends of the magnet, and at least one sensing device. The magnet generates a magnetic field, the angle of which changes as the shaft rotates. The pair of plates directs the magnetic field generated by the magnet towards the at least one sensing device. The at least one sensing device is sensitive to the changes in the angle of the magnetic field, which are indicative of an angular position of the shaft.
