Title Structure design of the moving magnet linear motor for the linear compressor
Abstract
Linear motor is a new type of motor which developed in recent decades,its scope of application is very wide,where the need for use of linear motion occasions can be linear motor to complete. Compared to the traditional rotary motor, linear motor has the advantages of simple structure,easy to adjust and control,strong adaptability.With the development of high energy permanent magnet materials, moving magnet linear motor has become a focus of research.
Firstly, the structure of the linear motor is compared,and the cylindrical linear motor is chosen as the research object.According to the design requirement and the basic working principle of the linear motor,the form and material of the components are determined.After determine the overall scheme of moving magnet linear motor,the moving magnet linear motor structure is optimizated by using Ansoft Maxwell through the two-dimensional modeling and processing.Finally, the assembly diagram of magnetic linear motor is drawn with Catia,and drew the two-dimensional figure of each component with CAD,completed the structure design of the dynamic magnetic linear motor.
