Analytical Calculation for Two Layers PMSRM based on Equivalent Magnetic Network Method

Due to the complex rotor structure and high harmonic magnetic field content of Permanent Magnet Synchronous Reluctance Machines(PMSRM), the vibration and noise of PMSRM are larger than that of traditional Permanent Magnet Synchronous Machines(PMSM).Taking a two layers PMSRM with squirrel-cage slot on rotor as an example, the Equivalent magnetic network method(EMNM) is used to analyze the air gap magnetic field under the action of no-load, and the radial electromagnetic force of the motor is further calculated. The structure of permanent magnet and magnetic barrier in PMSRM has great influence on the performance of the motor, and these parameters could be rapidly optimized by using the EMNM.
