中文说明：永磁同步电机自建模型仿真，此自建模型是基于dq轴的永磁同步电机，希望给初学自建烦琐子系统的同仁有点参考价值
English Description：
Permanent magnet synchronous motor self built model simulation, this self built model is based on the DQ axis permanent magnet synchronous motor, I hope to give some reference value to colleagues who are learning self built trivial subsystem
