Maglev trains can be divided into two categories: normally guided and superconducting. Normally-guided maglev, also known as normally-guided maglev, is represented by transrapid, a German high-speed normally-guided maglev train. It uses the electromagnetic attraction principle of ordinary DC electromagnet to suspend the train, and the suspension air gap is relatively small, generally around10 mm. The speed of the normally oriented high-speed maglev train is suitable for long-distance and rapid transportation between cities.
When the normally guided maglev train works, firstly, the electromagnetic attraction of the suspension and guiding electromagnet at the lower part of the vehicle is adjusted, and the magnet interacts with the windings on both sides of the ground track. The suspension gap between the vehicle and the running track is 10 mm, which is guaranteed by a high-precision electronic adjustment system. In addition, because the suspension and guidance are actually independent of the running speed of the train, the train can still enter the suspension state even when it stops.
Maglev technology is divided into four systems: track, vehicle, traction and operation control, with 16 core technologies. German, Japanese and China are the countries that have maglev train test or operation lines in the world. The maglev train is guided by electromagnetic force. According to constant magnetic attraction type and superconducting magnetic repulsion type.
