Calculation of Induction Electromotive Force of Linear Generator of High-Speed Maglev Train

To supply power for the appliances in high-speed EMS-maglev (electromagnetic suspension- magnetically levitated) vehicles, the position functions of self and mutual inductance in the linear generator were derived. The general formula for the electromotive force of the long stator linear generator and the position functions were derived by calculating the parameters with finite element method and analyzing the working conditions of the linear generator windings, long-stator linear synchronous motor windings and magnetic levitatingwindings. The calculated errors comparedwith the experimental results are less than 7% when the vehicle runs at 100 and 150 km/h.
