ABSTRACT:
A superconductive magnetically levitated railway is provided with six phases of propulsion-levitation-guidance ground coils arranged on both side walls of a track, and with a pair of superconducting magnets, which are mounted on the vehicle, corresponding to the six phases of the ground coils. The ground coils are a U-phase coil, a negative W-phase coil, a V-phase coil, a negative U-phase coil, a W-phase coil and a negative V-phase coil arranged successively at a 60.degree. pitch along both side walls of the track. As a result, higher harmonics of the magnetic field produced by the propulsion-levitation-guidance ground coils can be reduced. In addition, the number of layers of the ground coils can be reduced one and the number of ground coils can be decreased.
