The analysis and calculation of the article include the working principle of PMSM, the performance parameters of permanent magnet material, its characteristics and selection principle, the structure of PMSM, the steady-state performance of permanent magnet synchronous motor, the main parameters of permanent magnet synchronous motor, self-starting PMSM starting process. Finally, the design contents of permanent magnet synchronous motor are expounded: 1) to determine the design task; 2) to select the motor initial design parameters; 3) to check the motor performance indicators; 4) to adjust the motor parameters; 5) to determine the motor design.
