Abstract

A position sensing system for a switched reluctance machine such as that of an Integrated Starter Generator Turbogenerator or electric Supercharger wherein the system comprises a pair magnets a magnet carrier and a sensor element wherein the sensor element is mounted upon an end of a rotatable shaft of the SR machine and wherein the sensor element is mounted on a circuit board and sits in a well formed by the magnets which are arranged such that the magnetic flux follows a path similar to that of a horseshoe magnet 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.
