[0002] The track of the maglev transportation system is usually supported by the magnetic field generated by electromagnetic force. This system uses magnetic force to suspend the vehicle on the track, thereby reducing friction and resistance and improving operation efficiency. The single-width track arc maglev structure is one of the tracks of the maglev transportation system. The single-width track arc maglev structure adopts a single-track design, that is, there is only one track, and the structure also presents an arc shape.
