异步起动永磁同步电动机堵转参数包括堵转转矩和堵转电流，是评价电机起动性能的重要指标。针对异步起动永磁同步电动机堵转参数计算不准的问题，在分析了堵转时电机各转矩分量的基础上，采用时步有限元仿真电机的堵转试验，并通过合理地处理堵转参数曲线，得出电机的堵转参数。分别计算了5台异步起动永磁同步电动机的堵转参数，对比试验值，堵转转矩误差在10％以内，堵转电流误差在15％以内，证明了该计算方法可以满足工程需要。

Line-start permanent magnet synchronous motor locked rotor parameter which includes locked ro -tor torque and locked rotor current is one of the most important indexes evaluating self-startup abili-ty.According to the inaccurate calculation of line-start permanent magnet synchronous motor ( LSPMSM ) locked rotor parameters , torque component during the state of locked rotor was analysed.Time-stepping finite element method was used to simulate locked rotor test , and the locked rotor parameters were achieved by dealing with the locked rotor parameter curves reasonably.Five LSPMSMs locked rotor parameters were cal-culated.Compared with test values , the calculation error of locked rotor torque was within 10%, while that of locked rotor current was within 15%, which proved that the calculation method can meet the needs of en-gineering.
