磁悬浮的构想由德国工程师赫尔曼·肯佩尔于1922年提出。磁悬浮列车用电磁力将列车浮起而取消轮轨,采用长定子同步直流电机将电供至地面线圈,驱动列车高速行驶,从而取消了受电弓,实现了与地面没有接触、不带燃料的地面飞行。世界上第一列磁悬浮列车小型模型1969年在德国出现,日本是3年后研制成功的。到1979年,磁悬浮列车技术创造了517千米/小时的速度纪录。目前该技术已经成熟,可进入500千米/小时实用运营的建造阶段。磁悬浮列车有以下优点:
The idea of magnetic levitation was proposed by German engineer Hermann Kempel in 1922. Magnetic levitation train to lift the train to cancel the wheel and rail, the use of long stator synchronous DC motor to the ground coil power supply, driving the train at high speed, thus eliminating the pantograph, achieved without contact with the ground, without fuel Ground flight. The world’s first small model of maglev train appeared in Germany in 1969, Japan was successfully developed after 3 years. By 1979, maglev technology created a speed record of 517 km / h. At present, the technology is mature and can enter the construction phase of practical operation of 500 km / h. Maglev train has the following advantages:
