On the other hand, a reaction plate composed of a plywood obtained by pressing an aluminum plate on an iron plate 11 is fixed to the ground side and opposed to the vehicle field 13 at a distance of several mm to several tens mm, as shown in FIG. In response to the on-vehicle field, a VVVF (variable voltage variable frequency) inverter 16 supplies a three-phase voltage to each on-vehicle field to generate a moving magnetic field, which interacts with the eddy current generated on the reaction plate. A force is generated in the reaction plate in the longitudinal direction, and the reaction force generates a propulsive force in the on-vehicle field. At the start, the VVVF inverter 16 controls the vehicle propulsion by lowering the frequency and allowing a large current to flow, lowering the voltage, and increasing the frequency as the speed increases.
