Abstract: A rotary permanent magnet electrodynamic suspension device includes drive systems, a suspension system, an isolation layer. The drive systems are symmetrically provided in an axial direction of the suspension system. The isolation layer is provided between the suspension system and each drive system. The suspension system includes a magnetic wheel, a non-magnetic conductor and a support. The non-magnetic conductor has electromagnetic induction with the magnetic wheel. The support and the magnetic wheel are both ring-shaped, and the magnetic wheel is sleeved on an outer circumference of the support. The drive systems are configured to drive the magnetic wheel to rotate through electromagnetic induction. The magnetic wheel includes an annular array of permanent magnets to form four pole pairs based on radial magnetization and tangential magnetization. A permanent magnet electrodynamic suspension using the device is also provided.

Abstract: A vehicle running system based on rail transport, including a track, a framework, two levitation devices and a running device. The track is provided with a slot, in which the framework is provided. The levitation devices are provided between the track and the framework, and a top surface of the levitation device is fixedly connected to a bottom surface of the framework through a suspension structure. The running device includes two conductor plates and two running structures. The conductor plates are fixedly arranged on the inner wall of the slot, and are corresponding to the running structures. The reluctance force of magnetic wheels is converted into a driving force to drive maglev vehicles, and the levitation force is converted into a guiding force to realize the self-stabilization of vehicle guidance. A vehicle running method based on this system is also provided.
