Abstract
A position detection apparatus for a switched reluctance motor wherein a single sensor is used for detecting a rotor position and thus driving the motor. A sensing unit is provided with a single sensor for detecting a position of a rotor, a start signal generation circuit, for generating a start signal for aligning the rotor with a stator upon starting, a position detection signal input circuit for passing the position detection signal following the start signal, a drive control pulse generation circuit, for receiving an output signal from the position detection signal input circuit as a clock signal, sequentially shifting driving signals for respective phases and generating drive control pulses for respective phases, and a phase excitation circuit for logically combining phase drive control pulses from the drive control pulse generator with the start signal from the start, signal generation circuit and exciting the phases sequentially.
