摘　　要：通过对永磁同步无齿轮曳引机封星技术的论述及对封星电磁制动电梯溜车速度的分析,发现在永磁同步无齿轮曳引机中利用封星电磁制动可作为某些工况(尤其是层门区域)在制动器失效情况下的辅助安全保护措施,降低由于电梯制动器失效带来的风险。Through the discussion of the high speed short-circuit of motor rotor technology of permanent magnet machine and the analysis of the speed of the descending slipping car when it takes the high speed short-circuit magnet braking, which it can be used auxiliary safety protection measures, the risk or permanent magnet motor brake failure is reduced.
