| 摘要 |
According to the present invention, there is provided a superconducting magnetic levitation apparatus including a lifting magnet (1) for forming a track, a floating body (3) made of a high-Tc superconductor, and a cooling device (4) for keeping the floating body at a superconducting state, in which apparatus a plurality of coils (2) are disposed on the lifting magnet (1), to be used as propulsion electromagnets, for generating a magnetic field necessary for running the floating body, each of the coils is a flat, air-core coil, and the coils are excited by a polyphase alternating current. A commercial three-phase alternating current is readily available. <IMAGE> |
