Problems solved by technology

The advantage of this high-temperature superconducting maglev system is that it is easy to operate, but the disadvantage is that the magnetic field generated by the permanent magnet track is not high enough, and the capture field of the high-temperature superconducting block is not strong enough during the field cooling process, so it is difficult to obtain a large enough levitation force and guidance force
In the prior art, the magnetic field of the track is enhanced by optimizing the internal structure of a permanent magnet track. Although this can achieve certain improvements, it still cannot significantly improve the levitation / guidance performance of the high-temperature superconducting maglev system
