Internally magnetized capture type block high-temperature superconducting motor and generator

Abstract

The invention discloses an internally magnetized capture type block high-temperature superconducting motor and a generator, and relates to the field of motors. A magnetic block of the capture type block high-temperature superconducting motor uses an external coil for low-temperature magnetization to obtain a magnetic field, and then is transferred into the motor for use, so that the magnetizationand transfer operations are troublesome, and the transfer efficiency is low. The internally magnetized capture type block high-temperature superconducting motor comprises a driving part, a magnetizingpart and a shafting part, the driving part comprises a driving shell, a driving end cover and a driving stator, the magnetizing part comprises a magnetizing shell, a magnetizing end cover and a magnetizing stator, and the shafting part comprises a rotating shaft, a rotor, a driving end positioning assembly and a magnetizing end positioning assembly. The shafting part can move between the drivingpart and the magnetizing part to achieve magnetizing and driving work, and bearings for supporting the rotating shaft to rotate are arranged in the driving end positioning assembly and the magnetizingend positioning assembly and can be positioned and fixed to the driving end cover and the magnetizing end cover respectively. The rotor can be transferred to a driving position after being magnetizedin the motor, the operation is simple, and the transfer efficiency is high.

Superconducting motors are divided into two types: wires and blocks. Generally, blocks need to be magnetized to operate. The process of magnetization is called ...

AI Technical Summary

Problems solved by technology

Wire high-temperature superconducting motors are expensive and difficult to manufacture. Magnetized and captured bulk high-temperature superconducting motors have the characteristics of high efficiency, light weight, and relatively cheap prices. However, this type of motor magnet needs to use external coils for low-temperature Only by magnetizing can the magnetic field be obtained, and then transferred to the inside of the motor for use. The operation of magnetizing and transferring is troublesome and the efficiency is low, which has caused great difficulties for its wide application.
