Simulation and experimental study of moving-coil linear motor for linear compressor
Since the motor used for the linear compressor suffers such problems as stability and reliability,in this article a moving-coil linear motor is designed based on the Halbach permanent-magnet array form;the effects of the permanent-magnet ar-ray arrangement,air-gap thickness,inner-and-outer magnetic yoke and coil dimensions on the motor performance are solved with the help of the finite-element analysis.With the motor performance,assembly process and other factors taken into consideration,the structure and dimensions of the linear motor's each key component are optimized,so as to improve the inner-and-outer mag-netic yoke's space utilization,enhance the magnetic circuit's stability and eliminate the location of the concentrated electromag-netic induction intensity.Finally,the optimized motor's performance is simulated and verified through a series of experiment.
