摘　　要：针对线性压缩机直线电机的稳定性和可靠性问题,文中基于Halbach永磁体阵列形式设计了一种动圈式直线电机,采用有限元分析方法求解了永磁体阵列排列方式、气隙厚度、内外磁轭和线圈尺寸对电机性能的影响,综合考虑电机性能、装配工艺等因素,对直线电机各关键零部件的结构和尺寸进行了优化,提高了内、外磁轭的空间利用,增加了磁路的稳定性,消除了电磁感应强度集中位置,最后对优化后的电机性能进行了仿真分析和试验验证。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 array 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 magnetic yoke’s space utilization,enhance the magnetic circuit’s stability and eliminate the location of the concentrated electromagnetic induction intensity.Finally,the optimized motor’s performance is simulated and verified through a series of experiment.
