摘　　要：依据磁场分割的原则与方法,将磁路的气隙磁场分割为几个不同形状的柱形磁通管,利用该分割法设计了一种精度较高的最大气隙磁导和最小气隙磁导的解析计算方法,并完成了直线开关磁阻电机的电磁设计。然后采用有限元法计算得到的一相推力,验证了该设计方法的可行性。The air-gap magnetic field of magnetic circuit is divided into the cylindrical magnetic flux tube of several different shapes based on the principle and method of magnetic field division,an analytic calculating method of high precise maximum air-gap permenace and minimum air-gap permeance is designed by the division method,final,the electromagnetic design of linear switched reluctance motor is completed and a phase-thrust from calculation is verified by finite element method,and the result shows that the design method is feasibly.
