Abstract: Due to the weak damping properties of permanent magnet electrodynamic suspension（PMEDS）system, the position and orientation of the onboard magnets are easily disturbed under external forces, thereby affecting the electromagnetic force characteristics of the system. Several studies have been carried out on the electromagnetic force characteristics of the PMEDS system under a normal condition in which magnets are in a horizontal state. The influence of the position and orientation of the magnets o... More
