摘　　要：永磁同步电动机(PMSM)作为一种新型的交流同步电机,其在各行各业与日常生活中应用非常广泛;PMSM较小的转动惯量,较高的功率密度和运行效率等优点,使得其发展和应用空间很广泛;通过Scope模块对定子三相电流,电机转速、转子的转角、转矩以及dq轴电流进行观察,并对系统中的参数进行及时地修改;最后的结果表明,该调速系统具有启动快、调速特性好、响应速度快和稳定性好等优点,为电动机在实际的调速系统设计中提供了可靠的理论依据。Permanent magnet synchronous motor （PMSM） is a kind of new type AC motor with high power density, small moment of inertia, more efficiency, and so on. Its application and development space is very broad, and it＇ s widely used in all walks of life and daily life nowadays. Used Scope to observe the stator current, speed, rotor angle, torque and dq axle current when in the simulation. So that we could perfect the parameter timely. Finally, the results showed that the speed control system has some advantages such as start--up fast, speed regulation characteristics is good, quick response time, stability, and so on. For that, it can provide a reliable theoretical ba- sis for the actual speed control system design.
