Problems solved by technology

[0005] A common shortcoming of the above-mentioned maglev trains with magnets wound by conventional wires is that the levitation height is too low by about 10mm
This deficiency comes from the fact that the energy consumption of conventional wires limits the current-carrying capacity of the wires, causing the magnets to fail to provide enough attraction with the ferromagnetic track to achieve the purpose of increasing the levitation height
The poor current-carrying capacity of the wires and the low levitation height of the maglev train have brought a series of problems: due to the low levitation height, the requirements for the track infrastructure are increased; due to the resistance heating of the conventional wires, the volume and weight of the electromagnet are large , high energy consumption, low efficiency
[0011] The disadvantage of high-temperature superconducting bulk maglev vehicles is that the track is completely laid by permanent magnets, and the infrastructure cost for the track is too high
Moreover, the permanent magnet track will absorb stray ferromagnetic substances near the roadbed. Removing these substances will increase the line operation and maintenance costs, and it is very difficult. The ferromagnetic substances remaining on the track will increase the risk of maglev vehicle operation.
This kind of magnetic levitation formed by the magnetic flux pinning effect cannot realize the active control of the levitation height of the magnetic levitation experimental vehicle, and it is also a shortcoming that the high temperature superconducting block magnetic levitation vehicle cannot overcome
