摘　　要：直线振荡电机是直线压缩机的关键部件,其性能直接影响压缩机效率,采用等效磁路法构建了E型外磁轭式-圆筒型动磁式直线振荡电机的电磁结构模型,推导了电机的磁链、磁共能以及电磁力的表达式,分析了结构参数对电机性能的影响。最后采用静态比推力试验验证了等效磁路模型的最大误差为5.12%,为电机的结构设计和优化提供理论基础。The linear oscillation motor is a key component of linear compressors,and its performance directly affects the efficiency of the compressor.In this paper,the electromagnetic structure model of an E-type external yoke cylindrical moving magnet linear oscillation motor is constructed using the equivalent magnetic circuit method.The expressions of magnetic linkage,magnetic common energy and electromagnetic force of the motor are derived,and the influence of structural parameters on the performance of the motor is analyzed.Finally,the maximum error of the equivalent magnetic circuit model is verified to be 5.12%by the static specific thrust test,which provides a theoretical basis for the structural design and optimization of the motor.
