A maglev train is a high-speed maglev train system that adopts a non-contact electromagnetic levitation, guidance and drive system. Its speed can reach more than 500 kilometers per hour. It is the fastest ground passenger transportation in the world today. It has the advantages of fast speed, strong climbing ability, low energy consumption, low noise during operation, safety and comfort, no fuel, less pollution, and low price. .
And it adopts the elevated method and occupies very little cultivated land. Maglev trains mean that these trains use the basic principle of magnets to levitate on rails to replace old steel wheel and rail trains. The magnetic levitation technology uses the electromagnetic force in the magnet to hold up the entire train compartment, getting rid of the annoying friction and unpleasant clanging sound, and realizes the rapid "flight" without contact with the ground and without fuel.
The maglev train is the most fundamental breakthrough in railway technology since Stephenson's "Rocket" steam locomotive, some 200 years ago. The maglev train seems to be a new thing today, but its theoretical preparation has a long history.
The research on magnetic levitation technology originated in Germany. As early as 1922, German engineer Hermann Kempel proposed the principle of electromagnetic levitation on magnets, and in 1934 applied for a patent for a magnetic levitation train. After entering the 1970s, with the continuous strengthening of the economic strength of the world's industrialized countries, in order to improve the transportation capacity to meet the needs of their economic development, developed countries such as Germany, Japan, the United States, Canada, France, and the United Kingdom have successively started planning for maglev transportation systems. development.
