Abstract: A fault detection device for a superconducting electrodynamic maglev track includes a frame system and a detection system. The frame system is provided between two sidewall discrete figure-8-shaped coil tracks, and is provided with a signal processing device. The detection system is provided on each side of the frame system, and includes a lifting device and a clamping device. The lifting device is configured to adjust a vertical height of the clamping device. The clamping device is provided at an outer side of the lifting device, and is provided with a first connection portion and a second connection portion, which are respectively connected to a permanent magnet array and a receiving coil. The second connection portion is provided at periphery of the first connection portion. The receiving coil is electrically connected to the signal processing device. A fault detection method is further provided.

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.
