Abstract

The present disclosure provides a high-thrust high-temperature superconducting linear motor, which includes a mover part and a stator part, and the mover part includes a low-temperature refrigeration container, multiple rows of high-temperature superconducting coils arranged in the low-temperature refrigeration container, and a plurality of rows of high-temperature superconducting coils for cooling multiple rows of high-temperature superconducting coils. Refrigeration system of superconducting coils; the stator part includes a track body, multiple rows of power coils and multiple rows of suspension guide coils; in the direction perpendicular to the travel of the mover part, multiple rows of high temperature superconducting coils, multiple rows of power coils and multiple rows of suspension The guide coils are symmetrical to the central axis of the mover part, there is a row of power coils between two adjacent rows of high-temperature superconducting coils, and a row of high-temperature superconducting coils between two adjacent rows of power coils, and multiple rows of suspension guides The coils are distributed on both sides of multiple columns of high temperature superconducting coils. The maglev train using the superconducting linear motor of the present disclosure can improve the utilization rate of the magnetic field, obtain greater thrust and stability, and enable the train to have a higher running speed.

Description

technical field [0001] The disclosure belongs to the technical field of motors, in particular to a high-thrust high-temperature superconducting linear motor. Background technique [0002] The linear motor is an important device of the drive system of the high-speed maglev train. It includes a stator fixed to the ground and a mover fixed to the train. During the running of the train, the electric energy can be directly converted 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, with the continuous improvement of high-speed maglev train drive system's demand for high 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.
