  • Variable refluctance position transducer
    Patent number: 4772815
    Abstract: A rotational position transducer comprising a rotor having annularly spaced teeth and a stator with a pole face configuration comprising annularly spaced teeth opposing the rotor teeth. One or more pole windings are energized by an alternate current source, and one or more output voltages induced in pole windings are produced with components having a characteristic which varies as a function of the angular position of the rotor relative to the stator. The output voltages may be either amplitude or phase modulated as a function of rotor position. The transducer may be combined with a stepping motor having an identical pole configuration.
