High-power-density superconducting motor with limiting and adjusting structure

Abstract

The invention discloses a high-power-density superconducting motor with a limiting and adjusting structure. The high-power-density superconducting motor comprises a machine shell, a stator, a rotor, acirculating cooling mechanism, a rotor limiting mechanism, a stator limiting mechanism and a position adjusting mechanism. The stator is arranged in the shell; the rotating rotor is arranged in the stator; the stator and the rotor are sealed in the shell by a sealing plate at the front end of the shell; the circulating cooling mechanism is arranged in the shell; a rotor limiting mechanism is arranged on the sealing plate at the front end of the shell and a rear end cover of the shell; stator limiting mechanisms are arranged at the two ends of the stator; and a position adjusting mechanism isarranged between the sealing plate at the front end of the shell and the rear end cover of the shell to limit the length of the stator. According to the scheme, the stator iron core is fixedly arranged in the shell at a stable angle, and the relative positions of the rotor and the stator iron core are kept unchanged; an adjusting ring is controlled to limit the stator iron cores with different lengths; the circulating cooling mechanism ensures that the stator has a lower temperature while ensuring the working temperature of the rotor, and improves the power density of the motor.

Description

technical field [0001] The invention relates to the technical field of superconducting motors, in particular to a superconducting motor with a cooling function, a stator and a rotor assembled in cooperation, and suitable for stators of different sizes. Background technique [0002] Superconducting motor refers to the fact that the excitation winding is made of superconducting material and can carry high-density current under a strong magnetic field. A very strong current can be passed through it to generate a very strong magnetic field, that is, a superconducting magnet is formed. [0003] The superconducting motor is mainly composed of two parts, the stator and the rotor. In the superconducting generator, the stator needs to use non-magnetic high-strength materials to support the winding due to the high magnetic flux density. The rotor generally adopts a multi-cylinder structure, and the inner cylinder of the rotor is used for cooling Medium storage tank, such as a high-te...
