摘要
气隙磁场是表面贴磁式圆筒型永磁直线电机的重要参数,它对该种电机的推力密度、效率等性能影响很大。通过建立等效面电流模型得出了计算气隙磁场的准确解析公式,再与有限元法计算结果进行对比,得出了该解析法有效的结论。
The air-gap magnetic field is an important parameter for tubular PM linear mo- tor with surface-mounted permanent magnet. It has significant influence on the thrust force den- sity and efficiency. The accurate analytical formulas for calculating air-gap magnet field were given out through establishing equivalent surface current model. The analytical method is proved to be effective by comparing with the results of finite element method.
