摘要
在合理假定的基础上,建立了圆筒型永磁直线同步电动机的物理模型,以麦克斯韦方程为基础,推导出了电机的磁密表达式,进行了解析计算,并用有限元法验证解析结果。两种方法所得结果吻合较好,表明该解析法行之有效。
This paper deals with physical model of tubular PM linear synchronous motor （T - PMLSM） based on the proper hypothesis. Then, the magnetic flux＇s expression of T- PMLSM is introduced with the field theory which is based on Maxwell＇s equations. After that, the analytical results are given and compared with ones of FEM simulation, and agreed with each other well, verifying the feasibility of the provided analytical method.
