System for levitating and guiding object by electromagnetic attractive force

摘要

A system for levitating and guiding an object by a magnetic force, which is typically a superconducting magnetic support apparatus or a superconducting linear convey system, comprises a support member, a superconductor unit, disposed on the support member, including a container having an inner space, a superconductor material for trapping magnetic fluxes generated at the time of transition from the normal conduction state to the superconduction state of the superconductor unit, and a refrigerant supply unit for supplying the inner space of the container with a refrigerant for setting the superconductor material in the superconducting state, a convey member situated to face the support member, a magnetic material disposed on the convey member so as to face the superconductor material, and a magnet, situated on the support member, for generating magnetic fluxes which enter the magnetic material through the superconductor material.
