摘要
对磁悬浮列车中,利用气隙磁场的一阶、二阶齿谐波发电的直线发电机进行了理论分析,导出了直线发电机电枢绕组在两种连接方案下感应电动势瞬时值的表达式,继而导出了满足一阶齿谐波感应电动势同相位的条件,为磁悬浮列车中的直线发电机的设计提供了理论依据。
The linear generator used in magnetic levitation vehicle is investigated in this paper. Firstly the principles of the linear generator are introduced, then the formulae of electromotive force (EMF) induced by the slot harmonics in the airgap are deduced for two types of armature windings, and the design principles in which the phases of EMF are matched are presented. All these form the basic theories of the linear generator used in the magnetic levitation vehicle.
