Compared with the analytical and experimental results, it is confirmed that the permanent magnet eddy-current brake is an effective braking method and FEM is suitable for analyzing it.
All results show that permanent magnet type retarder using robust design technique can decrease braking torque fluctuation.
结果表明：采用稳健性设计的永磁式缓速器可以较好地改善制动力矩波动率。
