Abstract

As lots of harmonics are in the back-electromotive force (EMF) of Permanent Magnet Synchronous Motor (PMSM), an auxiliary rotor slot is presented to reduce the Total Harmonic Distortion (THD), to improve the waveform of back-EMF, and to make the waveform of it close to sinusoid. A 22 kW 3000 rpm PMSM is simulated by MagneForce software. The simulation results show that the THD is decreased by 48.4%, while the fundamental voltage amplitude is increased by 4.4%, and the waveform is closer to sinusoid after the auxiliary rotor slot is opened.
