Abstract：When the peak-to-valley complementary method is used to suppress the ripple torque of the permanent magnet brushless DC motor, the symmetry and sinusoidal of the two motor ripple torque waveforms are closely related to the suppression effect, and the accuracy of the position sensor directly affects the motor ripple torque. Waveform characteristics. Based on this, the phase difference, duty cycle and response speed of the output signals of the two position sensors during motor operation were measured and analyzed. Then the experimental platform was built to determine the symmetry and sinusoidality of the pulsating torque of the motor under two position sensor conditions. Finally, the suppression effect of the motor ripple torque during the operation of the two position sensors is compared. The results show that the suppression effect of the motor ripple torque is about 30% when the grating position sensor is running.
