摘　　要：针对永磁同步曳引机驱动电梯在无制动力（制动系统失效）情况下绕组封星时进行了运动学理论分析：分别应用平衡力分析法、能量守恒分析法、转矩系数法推导出绕组封星短接时电梯系统的稳定溜车速度，并给出了计算实例。The kinematics theory analysis are conducted to the high speed short circuit for permanent magnet synchronous traction machine in the case of absence of braking force （brake system failure）. The separately balance force analysis, the energy conservation analysis and the torque coefficient method are used to derive the stable down slipping speed at the winding circuit being shorted, and a calculation example is given in this paper.
