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.
