Abstract
An electromagnetic suspension system uses a linear motor having coils disposed around the outer periphery of a stator and permanent magnets disposed along the inner periphery of a mover. Wiring is routed through a gap between a first rod and a second rod. Thus, contact between the wiring and the second rod is avoided, and the wiring is protected. Consequently, it is possible to ensure reliability for the electric system of the electromagnetic suspension system.
