“…Up to now, there are two types of linear generators to be applied in EDS SC-Maglev and EMS Transrapid to provide power contactless for vehicle at a high speed. In [18]- [20], a linear generator consisting of threephase coils is proposed for EDS SC-Maglev, which is integrated into the superconducting magnet. Researchers investigate its characteristics and design the corresponding PWM converter.…”

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

“…In fiscal 2004 the final year of the five-year plan, special tests under simulated irregular conditions were performed to verify the safety and stability of the vehicle during test runnings. In addition, a combined propulsion levitation and guidance coil (PLG coil) 7) , a superconducting magnet which corresponds to 120 degree pitched propulsion or levitation ground coils 8) as well as a distributed-type linear generator system 9) were tested on the YMTL these had been developed in the RTRI's Kunitachi laboratories for the purpose of developing "cost reduction technology". The running tests conducted on the YMTL over a three-week period with one-week interval were considered as a single test series.…”
