Calculation of electromotive force of linear generator used in magnetic levitation vehicle

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.
