Abstract

The invention discloses a high-temperature superconducting motor. The high-temperature superconducting motor comprises a motor shell, a stator and a rotor which are sequentially arranged from outsideto inside in the radial direction, the stator is provided with a stator winding, and the rotor is provided with a superconducting magnetic block; the stator is provided with a wire hole extending in the axial direction, and a superconducting wire used for being electrified to magnetize the superconducting magnetic block is arranged in the wire hole; the motor shell is sealed, and two ends of the motor shell are provided with end covers which are matched with the motor shell in a sealing manner; and a cooling medium used for maintaining the superconducting wire and the superconducting magneticblock at a superconducting critical temperature is introduced into the motor shell, and the stator and the rotor are immersed in the cooling medium. The high-temperature superconducting motor breaks through the restriction of dynamic electrification of the superconducting wire, and improves the convenience and reliability of magnetizing of the superconducting magnetic block.

Description

technical field [0001] The invention relates to the technical field of superconducting motors, in particular to a high-temperature superconducting motor. Background technique [0002] High-temperature superconducting motors have been known in the prior art. They use the super large current-carrying capacity of superconducting wires at critical temperatures and the super-strong magnetic flux intensity after magnetization of superconducting magnetic blocks to greatly reduce the size of the motor. Of course, the "high temperature" here is relative to absolute zero, and the actual temperature is still lower than the superconducting critical temperature of superconducting wires and superconducting magnetic blocks. To ensure the stable operation of superconducting wires and superconducting magnetic blocks, they need to be continuously operated in a critical temperature environment. Both the superconducting magnetic block and the superconducting wire are located on the rotor. The ...
