摘要
为解决高速电磁型高速磁浮车辆供电问题,推导了直线发电机线圈自感及互感位置函数.用有限元法计算有关参数,并通过模拟列车运行情况下直线发电机线圈、长定子同步电动机绕组和悬浮电磁铁励磁线圈的工作状况分析所得数据,推导出各位置函数的表达式和直线发电机电动势通式.当列车速度为100和150km/h时,计算值与实验结果相比误差小于7%.
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 levitating windings. The calculated errors compared with the experimental results are less than 7% when the vehicle runs at 100 and 150 km/h.
