A position sensing system for a switched reluctance machine, such as that of an integrated starter generator, turbo-generator or electric supercharger wherein the system comprises a pair magnets 12,14, a magnet carrier 6, and a sensor element 8, wherein the sensor element is mounted upon an end of a rotatable shaft 4 of the SR machine, and wherein the sensor element is mounted on a circuit board 16, and sits in a well formed by the magnets which are arranged in a horseshoe arrangement, and whereby magnetic flux produced by the magnets is concentrated within the well of the magnet carrier in a direction normal to the axial direction of the shaft of the SR machine. A further sensor shield 10 surrounds the sensor element. |
