The invention discloses a high power density superconducting motor with a limiting structure, comprising a casing, a stator, a rotor, a circulating cooling mechanism, a rotor limiting mechanism and a stator limiting mechanism; the casing is provided with a stator; the A rotating rotor is arranged inside the stator; the sealing plate at the front end of the casing seals the stator and the rotor inside the casing; a circulating cooling mechanism is arranged in the casing; the sealing plate at the front end of the casing and the rear of the casing The end cover is provided with a rotor limiting mechanism; both ends of the stator are provided with a stator limiting mechanism. The structure of this case enables the stator core to be installed and fixed in the casing at a stable angle, and keeps the relative position of the rotor and the stator core unchanged; the circulating cooling mechanism ensures that the rotor excitation winding works in the superconducting excitation winding temperature region, and at the same time enables the stator to have Lower temperatures and higher line current densities further increase the power density of superconducting machines.
Description
technical field [0001] The invention relates to the technical field of a superconducting motor, in particular to a superconducting motor with cooling effect, and a stator and a rotor are assembled together. Background technique [0002] Superconducting motor refers to the fact that the excitation winding is made of superconducting material, which can carry high-density current in a strong magnetic field. A strong current can be passed through it to generate a strong magnetic field, that is, to form a superconducting magnet. [0003] The superconducting motor is mainly composed of two parts, a stator and a rotor. For example, a high-temperature superconducting motor, with the application number of 201921931861.6, records that the stator is provided with stator windings, and the rotor is provided with superconducting magnetic blocks; the motor A cooling medium for maintaining the superconducting wire rod and the superconducting magnet block at a superconducting critical tempe...
