Abstract

The invention provides a high-thrust high-temperature superconducting linear motor. The linear motor comprises a rotor part and a stator part, wherein the rotor part comprises a low-temperature refrigeration container, multiple columns of high-temperature superconducting coils arranged in the low-temperature refrigeration container and a refrigeration system for cooling the multiple columns of high-temperature superconducting coils, the stator part comprises a track main body, a plurality of columns of power coils and a plurality of columns of suspension guide coils, the rotor part moves in adirection vertical to the moving direction of the rotor part, the multiple columns of high-temperature superconducting coils, the multiple columns of power coils and the multiple columns of suspensionguide coils are all symmetrical about the central axis of the rotor part, a column of power coils are arranged between every two adjacent columns of high-temperature superconducting coils, a column of high-temperature superconducting coils are arranged between every two adjacent columns of power coils, and the multiple columns of suspension guide coils are distributed on two sides of the multiplecolumns of high-temperature superconducting coils. The linear motor is advantaged in that a maglev train using the superconducting linear motor can improve the utilization rate of a magnetic field, obtain greater thrust and stability, and enable the train to have the higher running speed.

Description

Technical field [0001] The present disclosure belongs to the technical field of electric motors, and specifically relates to a high-thrust high-temperature superconducting linear motor. Background technique [0002] The linear motor is an important device of the high-speed maglev train drive system. It includes a stator fixed to the ground and a mover fixed to the train. When the train is running, it can directly convert electrical energy into linear motion without other conversion equipment. Of mechanical energy. Compared with traditional rotary motors, linear motors have the characteristics of simple structure, easy maintenance, no contact, low noise, and more precise speed control. [0003] In recent years, as the high-speed maglev train drive system has continuously increased the demand for large thrust, high precision and operational stability of linear motors, more and more experts have begun to pay attention to and study the development and improvement of linear motors.
