Structural Study on Moving Magnet Compressor for Stirling Engine

Abstract

The article describes a structural study on moving magnet compressor for Stirling engine. The performance of Stirling engine is determined by the linear compressor. The article first establishes mathematics models for ordinary linear compressors and moving magnet compressors manufactured for test and analysis, then studies magnetic field distribution of linear moving magnet compressor by CAE, the results show that magnet analysis has an agreement with the measurements. A modified moving magnet compressor prototype is proposed based on the results.
