Abstract:This paper proposes a novel sensorless speedup method for doubly salient electro-magnetic motor (DSEM). Based on the characteristic that phase self-inductance varies with rotor position, accurate and quick estimation of rotor sector is achieved through three-phase response currents with only one test injection pulse needed. Besides, no negative torque will be produced by the test pulse unless the rotor passes the commutation instants. To improve the speedup performance, the rules for selecting the width of test pulse and acceleration are analyzed as well. Experiments on a 12/8-pole DSEM validate the correctness and feasibility of the proposed method.
