Abstract Sensorless control of 12/10 flux-switching permanent magnet(FSPM) motor with high-frequency pulsating sinusoidal signal injection was carried out on the basis of salient pole verification. The traditional signal modulation method was analyzed, and then a direct signal process method was proposed. The idea of the proposed method was that q-axis current signal of the estimated synchronous rotating reference frame processed through the band pass filter(BPF) directly multiplied by the square wave signal to get the position error signal, which could eliminate the low-pass filter to make the signal process simple. Lastly through experiment, the traditional signal process method and direct signal process method with high-frequency pulsating sinusoidal signal injection were compared to verify the validity of theory analysis on FSPM motor.
