China-made suspended maglev train powered by permanent magnets begins testing

In Japan, construction of the

Linear Chuo Shinkansen is underway as a high-speed line that runs between Tokyo and Osaka in about an hour. In the Linear Chuo Shinkansen, superconducting magnets are used to levitate the vehicle, but in China, development of a suspended magnetic levitation railway using permanent magnets is underway.

Below is a photo of the test route of the magnetic levitation railway that opened on August 9, 2022 in Xingguo County, Jiangxi Province, China. The test route is called 'Red Rotor', and unlike Japan's linear motor cars, it has a distinctive appearance that hangs from the rails.

The length of the test line is about 800m, and it is possible to run at a speed of 80km per hour with 88 passengers on board. In addition, after repeating the test several times, the test route was extended to about 7.5 km, and it is said that high-speed driving at 120 km / h is aimed.

The main feature of 'Red Car' is that the vehicle is levitated by permanent magnets instead of superconducting magnets. Magnetic levitation railways that use permanent magnets are said to have problems in terms of safety and stability, but ``Red Carriage'' realizes stable running by using AI technology. Thanks to AI-based driving stabilization, the Red Car can operate at speeds far exceeding 80 km/h, which is the general speed of subways in China, and construction costs are said to be one-tenth that of subways. I'm here.

In addition, it is said that China owns about 80% of the world's permanent magnet production capacity, and it is expected that China's transportation technology will greatly develop as a magnetic levitation railway using permanent magnets is put into practical use. Expected.
