摘  要：建立无槽式永磁直线同步电动机物理模型和分层解析模型。在此基础上，以矢量磁位作为求解变量得到励磁磁场和电枢反应磁场的二维解。以此分析不同电机的磁阻阻力和电磁推力随位置变化。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。

Abstract: Divided layers model and phytical model of slotless permanent magnet linear synchronous motor(PMLSM)were built.Magnetic vector potential is regarded as variables to gain solution of excitation magnetic field and armature response magnetic field.Through two-dimensional analytical method,detent force and thrust force of different motors were computed to change of location.The finite element method(FEM)was confirmed agreement with analytical method, indicating the validity of analytical method.
