摘要
为改善圆筒型永磁直线同步电动机的动态性能,通过改变次级永磁体形状的方法来减小推力波动,并用有限元法进行计算。计算结果证实了所提出方法的有效性。
In order to improve the dynamic performance of tubular-type permanent magnet linear synchronous motor, the paper presents a method of changing the shape of secondary permanent magnet to reduce the thrust fluctuation which is calculated by finite element method （ FEM ）. The calculated results prove effective for the mentioned method.
