Speed control system based on speed sensorless system is a research and project which is widely concerned by the international electric drive industry. The researchers found that the speed sensorless system has better rotation rate measurement, which is no longer affected by temperature, humidity, and other environments. However, there are higher r...

... will be cogging between the rotor and stator of the induction motor, and the air gap is toothshaped, not smooth, and uniform, so a harmonic magnetic field will be generated in the air gap of the motor. As shown in Fig. 1, when the motor rotates, because the winding magnetic potential curve is not sinusoidal, the harmonic magnetic field will generate harmonic voltage and current on the coil of the stator winding. Through the analysis of the obtained voltage and current, the harmonic quantity of the tooth slot can be obtained, and the magnitude of the ...
