Abstract

A transverse flux high-speed superconducting motor system is provided to solve the problem concerning practical application of a miniature high-speed and high-power-density superconducting motor. The transverse flux high-speed superconducting motor system comprises a stator external magnetic ring, a superconducting coil assembly, a stator special-shaped magnetic block, a rotor magnet steel group, a rotor, and a rotating shaft. According to the superconducting motor, the resistance-free characteristic of a superconducting winding is utilized, and intermittent direct current is fed in. The outer diameter of the superconducting motor is reduced based on the mechanical property of an annular superconducting winding, and the direct current carrying capacity of the superconducting winding and the speed of the superconducting motor are improved based on the quench and recovery characteristic of the superconducting winding. The scope of application of the superconducting motor in the field of high-speed motors is expanded.

Description

technical field [0001] The invention relates to a superconducting motor, in particular to a transverse magnetic flux high-speed superconducting motor system. Background technique [0002] With the rapid development of superconducting technology, superconducting wires have developed many types of superconducting motors at home and abroad due to their non-resistance and non-destructive properties, which are used in the fields of ship electric propulsion and wind power generation. This type of superconducting motor includes low-temperature superconducting motor systems using nickel-titanium alloys, and high-temperature superconducting motors using Bi2223 or YBCO strips. This kind of superconducting motor applies the superconductivity of the superconductor to the rotor of the motor, so that the superconducting coil can generate a high magnetic field density in a low temperature environment (such as 4.2K or 77K), which is 2~ 3 times the magnetic field density can effectively red...
