Abstract

Shaft position sensing is necessary in the switched reluctance (SR) motor in order to synchronize the phase excitation to the rotor position. In industrial applications, motor commutation often needs direct sensors to detect the rotor position. Being `Sensorless' does not mean that the motor no longer requires rotor positioning; it means the position information is obtained indirectly, and not through a shaft sensor. According to the inductance characteristics of the SR motor, this paper adopts the linear frequency modulated (FM) principle and the output of the FM converter to get the rotor position signal. Experimental results verify the feasibility of the proposed method.
