Abstract: An apparatus measures relative displacement between a first end and a second end of a shaft. The first and second ends being centered on a shaft axis. The apparatus includes first and second ferromagnetic plates. The first ferromagnetic plate has a first side and a second side and is connected to the first end. The first ferromagnetic plate is centered on the shaft axis and has a plurality of ferromagnetic teeth extending from the first side and in a first direction parallel to the shaft. The second ferromagnetic plate has a first side and a second side and is connected to the second end. The second ferromagnetic plate is centered on the shaft axis. The first and second ferromagnetic plates form a gap. The apparatus further includes a plurality of magnets having a magnetic field and a sensing device. The magnets are coupled to the first side of the second ferromagnetic plate. The sensing device is disposed within the gap for sensing a magnetic flux of the magnetic field.

Abstract: A device for implementing a method for controlling a switched-reluctance motor having a rotor and excitable phases is disclosed. The device comprises a controller and an interface for implementing a master control routine including a pre-alignment stage, a preliminary stage, and a primary stage. During the pre-alignment stage, the rotor is rotated to an initial position corresponding to one the phases being aligned. During the preliminary stage, the rotor is rotated from the initial position is rotated in a desired direction. During the primary stage, any operational losses are minimized when the rotor is positioned in a holding position.
