摘要
提出中低速磁悬浮列车采用普通异步直线电动机作为牵引动力,其电机的法向力是影响列车稳定悬浮的重要因素,并对此进行了试验研究。分析了电流、频率以及气隙与法向力的关系,得出在法向力不大于车体重量十分之一的情况下,通过调节列车动态悬浮控制参数,可使列车稳定悬浮运动的结论。
It is pointed out that asynchronous linear motor is used as the traction power for mid-to-low speed maglev trains and thatthe normal force of the motor influences greatly the steady levitation of the train. Experimental study is done. The relationships betweencurrent, frequency and gap with the force are analyzed. Conclusion is made that steady levitation of the train may be reached throughadjustment of dynamic levitation control parameters when the normal force does not exceed one tenth of the carbody weight.
