摘　　要：简要介绍了一种新型直线电机的结构和原理,用MAGNET软件对具有不同结构的电机的电磁场进行了数值计算。通过计算得出了低速永磁直线同步电机的二维磁场分布和气隙磁密的变化波形。为设计新型低速永磁直线同步电动机提供了一种方法。The construction and principle of a new type of linear motor was introduced briefly. The MAGNET software was applied to carry on the numerical calculation and analysis of the magnetic field of the low-speed PM linear synchronous motors. The planar distribution of the magnet field and waveform change of the air gap flux density of the low-speed PM linear synchronous motors was worked out through the calculation, so as to provide a good method to design this type of linear motor.
