Built-in magnetic steel non-metal support structure and Stirling refrigerator and power generator

Abstract

The invention provides a built-in magnetic steel non-metal support structure, a moving magnetic linear motor structure and a Stirling refrigerator and a power generator. The built-in magnetic steel non-metal support structure comprises an outer retaining ring, an upper retaining ring, a lower retaining ring and magnetic steel. The outer retaining ring, the upper retaining ring and the lower retaining ring are all made of a non-metallic material. The magnetic steel is adhered to the inner wall of the outer retaining ring. The upper retaining ring and the lower retaining ring are respectively abutted against two ends of the magnetic steel. Compared with the prior art, the outer retaining ring is used to effectively regulate the outer circumferential position of the magnetic steel. A bondingrequirement for the magnetic steel is reduced compared with an external magnetic steel type. The upper and lower retaining rings effectively define axial movement of the magnetic steel. Manufacturingcost is greatly reduced, production efficiency is improved, and high reliability is realized by a simple structure.

Description

technical field [0001] The invention relates to the technical field of Stirling cycle refrigerators, in particular to a built-in magnetic steel non-metal support structure, a moving magnet linear motor structure, a Stirling refrigerator and a generator. Background technique [0002] Linear motors are the most important components in Stirling refrigerators and generators, which are composed of coils, permanent magnetic steel components, and inner and outer stators. Linear motors can be divided into two types: moving coil type and moving magnet type. As the moving coil motor needs high-frequency reciprocating motion of the electrified coil, it is difficult to ensure the reliability of the coil electrification. Its service life and performance reliability are guaranteed. [0003] With the development of linear motors, moving magnet motors are widely used. The moving parts of the motor become magnetic steel components, and the coils and inner and outer stators are fixed. This g...

AI Technical Summary

Problems solved by technology

The bottleneck of the reliability and life of the moving magnet linear motor lies in the moving magnet assembly. The magnet steel of the existing moving magnet assembly generally adopts an external type, and the bonding force, bonding life, and bonding temperature resistance to the magnet steel are relatively low. Strict, high manufacturing cost, low production efficiency
