摘　　要：常导高速磁浮列车由长定子直线同步电机驱动,其定子由轨道构成,转子由车载悬浮电磁铁构成,其悬浮和推进电磁场的研究对保证列车悬浮系统和推进系统的性能和可靠性具有重要意义。采用有限元法研究了常导高速磁浮列车的悬浮和推进电磁场。分析和计算结果表明,由于定子齿槽和材料不连续的影响,悬浮力和推力都存在六倍频的波动。A normal high speed magnetic levitation vehicle is driven by a long stator linear synchronous motor, the stator is the magnetic rail and the rotor ismade of the supporting electromagnets attached to the vehicle. The study on thelevitatingand propulsive electromagnetic fields of the vehicle is of great importance to the performance and reliability of levitation and propulsion systems. The levitating and propulsive electromagnetic fields of normal high speed magnetic levitation vehicle is studied using finite element method in this paper. According to analysis and calculation, the sixfold frequency undulation is found inthrust and levitation force due to the influence of the stator grooves and the material＇s discontinuousness.
