Problems solved by technology

Relatively speaking, the integration of levitation, guidance and drive of traditional superconducting maglev trains is not high
In addition, the independent motor uses an independent winding track-laying type and a permanent magnet track-laying linear motor, which needs to lay a permanent magnet track or an excitation track on the track, which is relatively expensive; and the magnetic field on the lower surface of the track is not Can be applied, the utilization rate of the magnetic field energy of the entire magnetic track system still has room for improvement

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a superconducting maglev train. Background technique [0002] At present, it is known that the traditional superconducting maglev train uses the diamagnetism and lateral stability of the superconductor in the superconducting state to form a force on the magnetic track, so that the train has a levitation-guiding function, and then it is driven by an independent motor. Relatively speaking, the integration of levitation, guidance and drive of traditional superconducting maglev trains is not high. In addition, the independent motor uses an independent winding track-laying type and a permanent magnet track-laying linear motor, which needs to lay a permanent magnet track or an excitation track on the track, which is relatively expensive; and the magnetic field on the lower surface of the track is not can be applied, the utilization rate of the magnetic field energy of the entire ...
