  • Patent number: 11834078
    Abstract: A levitation, propulsion and guidance integrated magnetic levitation system and an improvement method of levitation and guidance. The system includes a maglev train and a maglev track. The maglev train is provided with a permanent magnet array. The maglev track is provided with a driving device and a levitation driving device in sequence along a running direction of the maglev train. An iron plate is arranged in the middle of the maglev track. The driving device accelerates the maglev train from 0 to take-off velocity. The levitation driving device provides a driving force and a levitation force for the maglev train. The iron plate enables the centered running of the maglev train.

  • Patent number: 11801756
    Abstract: A permanent magnet electrodynamic suspension system includes a conductor track and a suspension and guidance device. The conductor track is disposed on a roadbed, and the suspension and guidance device is disposed above the conductor track. The suspension and guidance device includes a first permanent magnet array and a second permanent magnet array. The first permanent magnet array and the second permanent magnet array are the same in the magnetization direction arrangement. The first permanent magnet array and the second permanent magnet array are arranged perpendicular to each other. A guidance method for the permanent magnet electrodynamic suspension system is further provided.

  • Patent number: 11745598
    Abstract: A magnetic wheel driving device and a driving method using the same. The magnetic wheel driving device includes a vehicle body, a guide rail system, at least two magnetic wheel systems and a power system. The guide rail system includes two conductor plates, respectively arranged at two sides of the vehicle body. The at least two magnetic wheel systems are symmetrically arranged at two side walls of the vehicle body. A gap is provided between each magnetic wheel system and the corresponding conductor plate. The power system is configured to drive the at least two magnetic wheel systems to rotate.

  • Patent number: 11366038
    Abstract: A vibration test bench for electrodynamic-suspension magnetic levitation trains and a testing method using the same. The vibration test bench includes an adjustable track mounting surface, a track base, a guiding track and a simulated levitation device. The track base includes a first track base and a second track base. The first track base and the second track base are respectively provided at two sides of the adjustable track mounting surface. The guiding track is arranged at a bottom of the track base and can be embedded in the T-shaped bolt mounting grooves on the adjustable track mounting surface to move. The simulated levitation device is arranged on the track base and is configured to levitate the magnetic levitation train between the first track base and the second track base.
