The invention discloses a magnetic suspension system based on high temperature superconducting thin films and coating conductors thereof, the system comprises a suspended body, a low-temperature container and a permanent magnet bulk, the main body structure of the suspended body is formed by high temperature superconducting thin films or high temperature superconducting tapes in a layered alternatively overlapping combination way, the suspended body is fixed to the interior of the low-temperature container and is integrated with the low-temperature container as one, in the low-temperature container, a temperature condition of the suspended body in a superconducting state is maintained, so that the suspended body is in a suspension state relative to the permanent magnet bulk in the superconducting state. According to the invention, the system utilizes high-level biaxial texture characteristics of the epitaxially-grown high temperature superconducting thin film and the coating conductor thereof in crystal orientation, the good magnetic flow resistance performance of a superconductor is realized, suspension effects including large area and high displaying degree can be realized in a permanent magnet, so that the system of the invention has advantages of low weight, large design area, simple materials, low cost, significant effects and the like.

Description

technical field [0001] The invention relates to an electromagnetic power device, in particular to a magnetic levitation device, which is applied to the technical field of special devices and systems for maintaining the balance state of frictionless and contactless suspension. Background technique [0002] Superconducting magnetic levitation is divided into two categories in principle. One is to use the magnetic field generated by superconducting coils to repel each other with the magnetic force of other coils to achieve magnetic levitation. The other is to use the Meissner effect of the superconductor itself, that is, the external magnetic field Anti-magnetic flux phenomenon, so as to achieve the magnetic levitation effect, the magnetic levitation technology makes the object in a non-friction, non-contact suspension equilibrium state, it integrates electromagnetics, electronic technology, control engineering, signal processing, mechanics, dynamics as one of the typical Mecha...

Problems solved by technology

However, the preparation of the textured block is difficult, the raw materials used are many and expensive, the yield is low, and the c-axis texture is obtained by directional growth, but the crystal orientation in the ab plane is difficult to control, and the in-plane orientation is not good, so it is difficult to achieve very Good magnetic levitation effect, and the bulk superconducting material itself has high quality requirements, which affects the levitation efficiency
