This paper proposes a new method to estimate the shaft position of a switched reluctance motor (SRM). By on-line estimating the self-inductances of the motor, the shaft position of the SRM is obtained, and a closed-loop drive system can thus be achieved. The drive system performs well in both the pulse-width-modulated (PWM) region and the single pulse region. The adjustable speed range of the system is from 20 r/min to 2000 r/min. In addition, the drive system is automatically started from standstill to a required speed.
