摘要：In the electrical engineering education, modelling and dynamic simulation represent tools in order to understand behaviours of the different components for electric drive-systems in transitory regimes. This paper proposes a method to simulate the electromagnetic field of Permanent Magnet Synchronous Motor (PMSM). Based on the fundamental principle of traditional magnetic circuit design, the simulation model of Permanent Magnet Synchronous Motor (PMSM) is established by the ANSYS software. The load magnetic field of the motor is calculated. The magnetic field distribution of the motor is obtained. The performance of the maximum torque output under the different number of magnetic pole pairs, the permanent magnet in different sizes and the different rotor core thickness are analyzed in detail. Finally, the simulation results can provide the theoretical foundation for optimization design of the permanent magnet synchronous motors.
