초록 ▼

A superconducting magnetic levitated train and train system which includes a plurality of cars connected to each other, a group of superconducting magnets attached to the cars and a coil provided on the ground so that the superconducting magnetic levitated train is levitated by the magnetically induced repulsion between the superconducting magnets and the coil on the ground. The invention is characterized in that the superconducting magnet on a specified car has a predetermined stability margin which is larger than the stability margin of a superconducting magnet on the other cars. A method of controlling the superconducting magnetic levitated train which includes detecting a driven state of a superconducting magnet on a specified car and varying and controlling the travelling conditions for the train so that the stability margin of the superconducting magnet on the specific car is changed in accordance with the command from a train control. A superconducting coil for the superconducting magnetic levitated train includes a coil of a composite superconducting wire composed of multifilmentary NbTi wire having a low copper ratio. The outer surface thereof is coated with thin high-purity aluminum or the wire accommodates high-purity aluminum at the central portion of the cross section thereof.
