A superconducting synchronous motor

Abstract

Disclosed is a superconductive synchronous motor. A superconductive coil is fixed in a cylindrical sealed rotor inner cavity; a sealed outer cover covers the rotor inner cavity; a vacuum nozzle is arranged on the outer cover; the outer cover is fixed on a stator shell through a bearing; one end of the rotor inner cavity and one end of the outer cover are connected with a rotating connector; the other end of the rotating connector is simultaneously connected with a refrigerant feeding pipe and a refrigerant discharging pipe; the other end of the rotor inner cavity is fixedly connected with the other end of the outer cover; two leading-out ends of the superconductive coil are connected with the inner end of a copper sheet; the copper sheet penetrates in the rotor inner cavity and the outer end of the outer cover and then is connected with a power source through a power line; and the two leading-out ends of the superconductive coil are also connected with a superconductive switch. According to the specific connection structure of the superconductive synchronous motor, a superconductive wire of the superconductive switch is connected with the two leading-out ends of the superconductive coil; a section of the superconductive wire clings to a heater; and a power line of the heater penetrates in the rotor inner cavity and the outer cover and then is connected with a power source of the heater. The superconductive synchronous motor is high in reliability, high in efficiency and long in service life.

Description

technical field [0001] The invention relates to a superconducting synchronous motor. Background technique [0002] A synchronous motor is a device that converts mechanical energy into electrical energy. The two main components that make up the motor are: the rotor that can generate a specific magnetic field in the surrounding space and the stator composed of coils. When the mechanical energy drives the rotor, the rotor's own magnetic field also rotates together, and the changing magnetic field will induce current in the stator coil, which is a synchronous generator. The alternating current is passed into the stator coil to generate an alternating magnetic field in the space around the rotor, and the magnetic field of the rotor itself moves synchronously with the alternating magnetic field, which is a synchronous motor. [0003] The synchronous motor generates the field source of the magnetic field that moves synchronously with the rotor around the rotor, which is usually r...

AI Technical Summary

Problems solved by technology

However, its excitation current still needs to be introduced through brushes / slip rings or rotating rectification modules, there is a rotating contact link, and the reliability and service life need to be improved

For superconducting synchronous linear motors, because the rotor needs to move for a long distance, the power supply attached to the rotor increases the load on the motor and reduces the efficiency of the motor
