Abstract

This paper proposed an analytical method for the calculation of electromagnetic toque in a Permanent Magnet-assisted Synchronous Reluctance Motor (PMASynRM) based on equivalent magnetic network model. The Fourier expression of the electromagnetic torque considering harmonic is theoretically analyzed and simulated. With the aim of reducing torque ripple, the effect of the flux barrier angle on the electromagnetic torque and torque ripple is theoretically studied and simulated in one pole asymmetry and one pole pairs asymmetry structure. Finally, the optimal flux barrier angle is given. There is a good consistence between theoretical and simulation result.
