Abstract In this paper, a new sensorless control method for switched reluctance motor is proposed to reduce the limit of its application due to additional position sensors. The proposed method is based on the logic relationship of phase inductance which varies regionally with the change of rotor position. The rotor position can be divided into several regions, and the position pulse signal of each phase is obtained by recognizing the position regions. According to the position pulse signals, the estimated rotor position can be calculated and then sensorless operation is achieved. Considering that the different conditions caused by the change of the turn-off angle, the paper analyzed each condition and a unified algorithm is carried out. The proposed method is simple for calculation and no pre-stored magnetic characteristic of SRM is required. Thus this sensorless technology is easy to implement and it performs well on time. Simulation and experimental results have verified the validity of the method.
