A heat-pipe-cooled wrap-around superconducting motor

Technical field

The invention relates to a heat-pipe-cooled wrap-around superconducting motor.

Background technique

At present, superconducting motor technology is becoming more and more mature, and it is showing its increasingly broad development prospects. However, the structure of the existing superconducting motor is still quite complex, the internal layout is not very reasonable, and the volume and weight are relatively large. Therefore, it is necessary to manufacture a superconducting motor.

SUMMARY OF THE INVENTION

In order to overcome the existing situation, the superconducting motor technology is becoming more and more mature, and it is showing its increasingly broad development prospects, but the structure of the existing superconducting motor is still quite complex, the internal layout is not very reasonable, and the volume and weight are still relatively large. Therefore, there is a shortage of a superconducting motor with a simple structure, a reasonable internal layout, and a relatively small volume and weight. The present invention provides a heat-pipe-cooled wrap-around superconducting motor, which has a simple structure, low manufacturing cost and less investment. , which can reduce the economic burden of users.

The technical solution adopted by the present invention to solve the technical problem is as follows: the center of the superconducting motor is a rotor, a permanent magnet is fixed on the rotor, the permanent magnet can be disassembled and re-installed, the center of the rotor is the rotor shaft, and the rotor is centered on the rotor. The periphery is surrounded by an array of mutually symmetrical superconducting coils. The superconducting coils are filled with liquid nitrogen. Several heat pipes are installed around the liquid nitrogen. The periphery of the heat pipes is surrounded by a vacuum layer. The end cover, there are fixing screws on the end cover, and the fixing screws are used to fix all the objects in the casing. After the superconducting coil of this superconducting motor is powered on, the superconducting coil stores magnetic energy, and the magnetic energy stored in the superconducting coil makes the rotor rotate (a permanent magnet is fixed on the rotor) to output power to the outside.
