摘要：
A switched reluctance motor (10) provides position and speed detection without a shaft position sensor. At least one of the stator pole faces (54) and/or at least one of the rotor pole faces (60) has an irregularity such as a notch (52 and/or 58) providing a perturbation or blip (70, 82) in the inductance profile (72, 76, 84) of the motor (10) during rotation of the rotor (14) indicative of the position of the rotor (14) relative to the stator (12). The frequency of the perturbations indicates motor speed.
