Abstract: With the development of peoples life, the demand of quiet airconditioning is higher and higher. However, because of the higher speed, the noise of inverter compressor is more easily to appear. This paper is aimed at studying the angle and subsection of rotor skew, and analyzed the influence on the EMF and cogging torque. Ultimately, the influence of rotor skew on the efficiency and noise of the PMSM and compressor was specified.
