摘　　要：建立单相电源供电三相永磁同步电动机在转子d-q旋转坐标系下的动态数学模型;用对称分量法分析单相电源供电的三相永磁同步电动机电路系统,计算起动和稳定运行时所需的移相电容器的数值;用Matlab构建系统仿真模型和编写仿真程序,通过实例对单相电源供电的定子绕组Y形接法的异步起动三相永磁同步电动机的起动性能进行仿真分析,并与三相电压供电的情况进行了对比分析,仿真结果与理论分析相符。A dynamic mathematical model of the three-phase permanent magnet synchronous motor （Three-Phase PMSM） driven by a single-phase power with its rotor under d-q rotating coordinate system is established. To calculate the phase-shift capacitor parameters required for starting and for a stable operation, a symmetrical component method is used to analyze its circuit system. Matlab is adopted to build a system simulation model and design a simulation program. Simulation analysis of the starting performance for the asynchronous starting Three-Phase PMSM of single-phase power supply with Y-shaped stator windings is in agreement with the theoretical analysis.
