Superconducting magnetic transmission system

Abstract

The invention discloses a superconducting magnetic transmission system which comprises a prime motor side rotor and a load side rotor, a plurality of HTS high-temperature superconducting magnetic poles are laid on the surface of an iron core of the prime motor side rotor in the circumferential direction, and the residual magnetism directions of the adjacent HTS high-temperature superconducting magnetic poles are opposite; an HTS high-temperature superconducting closed conductor layer is fixed on the surface of an iron core of the load side rotor, and an air gap is reserved between the HTS high-temperature superconducting closed conductor layer and the HTS high-temperature superconducting magnetic pole; when an external prime mover drives the prime mover side rotor iron core to rotate, the HTS high-temperature superconducting magnetic pole generates a rotating magnetic field, the rotating magnetic field acts on the HTS high-temperature superconducting closed conductor layer to induce current, and the induced current is subjected to the effect of Lorentz force in the magnetic field to drive the load side rotor to drive an external load to rotate, so that magnetic transmission is achieved. The HTS high-temperature superconducting magnetic pole is used for replacing an existing permanent magnet, and the HTS high-temperature superconducting wire is used as the conductor layer, so that the power density and the output torque of the system can be greatly improved, the temperature rise of the system is reduced, and the operation reliability of the magnetic transmission system is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of superconducting electromagnetic devices, and more specifically relates to a superconducting magnetic transmission system. Background technique [0002] As we all know, compared with permanent magnets, high-temperature superconducting (HTS) bulk materials in the superconducting state can capture more than ten times the magnetic field strength of permanent magnets of the same size, and more than a thousand times the energy density of permanent magnets; Compared with resistive materials such as copper and aluminum, high-temperature superconducting (HTS) wires have high current-carrying density, low energy consumption, and do not generate Joule heat when flowing in a superconducting state. Due to the above significant advantages, high temperature superconducting materials are widely used in basic scientific research, medical and health, transportation, defense industry, electrical engineering and other fields...
