Title Linear compressor performance simulation of moving magnet linear motor analysis
Abstract
Linear compressors are widely used in many fields of aerospace, space exploration, as well as low-temperature superconducting electronics and so on. The linear compressor using a linear motor drivers, board support and gap seals spring technology to ensure the long life of the compressor and high reliability applications. Moving magnet linear motor is a linear motor. Because of high performance and high reliability make moving magnet linear motor in the linear compressor of the most widely used. It is because of the good static and dynamic characteristics and therefore has a very broad application prospects, there is currently very popular attention. In this thesis, electromagnetic field simulation software ansoft maxwell finite element model of the motor, its 2D analysis of static characteristics and dynamic characteristics of the model, based on the analysis, Discussion of moving magnet linear motor design optimization of parameters is the possibility.Moving magnet linear compressor general method of mechanical and electromagnetic systems designed to build on the future of moving magnet linear motor design and research have a certain reference value.
