  • Position sensing system
    Patent number: 10110096
    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.
    Type: Grant

  • Electrical machine
    Patent number: 9559570
    Abstract: An integrated starter generator device comprising a housing, a stator and a rotor contained within the housing, the device further comprising control electronics operable to configure the device as either a starter or generator and contained entirely within the housing. The device may include a high current terminal having brass and rubber bonded together. The rubber forms both a sealing and an insulating function.
