Abstract

The invention discloses a superconducting motor with ultra-low loss, which comprises an enclosure, a stator and a rotor, wherein the rotor is in an iron-core-free structure and mainly comprises a pole shoe, a rotor spider and a hollow rotating shaft; the pole shoe is wound with an exciting winding; the exciting winding is a superconducting coil; for the stator, a cooling tube is arranged in each stator slot based on the traditional structure; the enclosure comprises a housing; a spiraltron is wound on the outer side of the housing; a heat-proof radiation layer is arranged on a tooth surface of the stator; and cooling media are charged into the spiraltron, the cooling tubes, collecting tubes and the hollow rotating shaft. The superconducting motor with the ultra-low loss is very low in motor loss; the efficiency of the superconducting motor can reach above 99%; no dewar is arranged in an air gap; and the small air gap becomes possible; the motor is low in heat leakage and high in power density; and the refrigeration cost is low.

Description

Technical field

[0001] The invention relates to low-temperature transmission and motor technology, in particular to a superconducting motor with ultra-low loss and low cooling cost. Background technique

[0002] Since the discovery of high-temperature superconducting materials in 1986, researchers have conceived the use of high-temperature superconducting materials to manufacture high-performance motors. There are three types of high-temperature superconducting motors currently being studied: the first type is full-superconducting. Both the stator and the rotor use high-temperature superconducting materials, and the rotor is connected to DC without loss, but the superconducting material in the stator will produce a large amount in an alternating magnetic field. The second type uses high-temperature superconducting in the stator and the conventional structure of the rotor, which has the same problems as the first type; the third type is the conventional stator, and the rotor uses ...
