摘　　要：本文针对三种不同永磁体阵列结构,分别建立了有限元模型,运用麦克斯韦方程组和虚功原理,对各自的气隙磁场分布和洛伦兹力波动进行计算,通过对比结果得到了较为优化的永磁阵列结构,为短行程直线直流电机结构设计提供理论依据。In this paper,three different permanent magnet（PM） array structures are established by finite element model.Using Maxwell＇s equations and the virtual principle,the magnetic field distribution of airgap and the fluctuation of Lorentz force are calculated.An optimized PM array structure is achieved by comparing these simulation results,which provides a theoretical basis for the short stroke linear DC motor optimization design.
