Title:
SUPERCONDUCTING MAGNETIC TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/044954
Kind Code:
A1
Abstract:
Disclosed in the present invention is a superconducting magnetic transmission system, comprising a prime mover side rotor and a load side rotor, wherein a plurality of high-temperature superconducting (HTS) magnetic poles are circumferentially laid on a surface of an iron core of the prime mover side rotor, and the residual magnetism directions of adjacent HTS magnetic poles are opposite; an HTS closed conductor layer is fixed to a surface of an iron core of the load side rotor, and an air gap is reserved between the HTS closed conductor layer and the HTS magnetic poles; and when an external prime mover drives the iron core of the prime mover side rotor to rotate, the HTS magnetic poles generate a rotating magnetic field, the rotating magnetic field acts on the HTS closed conductor layer to induce a current, and the induced current is subjected to a Lorentz force in the magnetic field, and drives the load side rotor to drive an external load to rotate, thereby achieving magnetic transmission. In the present invention, the HTS magnetic poles are used to replace existing permanent magnets, and an HTS wire is used as the conductor layer, so that the power density and output torque of the system can be greatly increased, the temperature rise of the system is reduced, and the operational reliability of the magnetic transmission system is effectively improved.
