摘　　要：推导出永磁同步电动机的定子侧绕组的电压约束方程式,建立三绕组永磁同步电动机在d-q-0坐标系下的动态数学模型,对电机的起动瞬态特性进行分析;运用对称分量法分析三相永磁同步电动机的电路系统,计算起动和运行时需要的电容值;根据牵入同步判据,计算不同负载下所能牵入同步的最大转动惯量。通过实例对三绕组永磁同步电动机牵动负载的起动过程进行仿真分析,结果表明在单相电源供电系统下,可以选择合适的电容值使其起动和运行。The voltage constraint equations of the winding on stator side of the permanent magnet synchronous motor are deduced. The dynamic mathematical model of three-winding permanent magnet synchronous motor was constructed in d-q-0 coordinates system to analyze the starting transient performance of the motor. The symmetrical component method is used to analyze the circuit system of the three-phase permanent magnet synchronous motor,and calculate the needing capacitance values of starting state and running state. According to the criterion of pull-in synchronization,the maximum rotational inertia of pull-in synchronization is calculated with different loads. The simulation analysis for the starting process when three- winding permanent magnet synchronous motor pulls the load was conducted with an instance. The results show that the permanent magnet synchronous motor supplying with single-phase source can start and run with appropriate capacitance value.
