Modeling and Analysis of a Linear Generator for High Speed Maglev Train

This paper investigates a linear generator (LIG) for application in high speed maglev train. Its configuration and working principle are introduced detail. The mathematic models of magnetic field induced voltage established by the equivalent circuit method law electromagnetic induction respectively, through which characteristics LIG impact factors analyzed preliminarily. An analytical numerical is proposed to analyze further, finite element model applied calculate accurately used calculation discrete way. relationships amplitude speed, frequency clarified, providing basis design power supply system on vehicle. Finally, experiments carried out performance test bench magnet real vehicle respectively validate analysis results.
