摘　　要：针对高性能电液比例阀所需的大推力驱动器,提出了5种结构形式音圈电机,利用电磁仿真工具ANSYS Maxwell,对不同结构的音圈电机的推力和磁场分布特征进行了计算,分析铁芯半径和线圈位移对不同结构的音圈电机推力和磁场分布的影响。结果表明,5种结构中内磁式无铁芯、线圈紧贴外壳、永磁体分段设计的结构有最大推力,可达75.29 N,并通过实验得到了验证;在永磁体两侧添加导磁环以及适当分段永磁体,均能有效提升音圈电机的推力。For the high performance electro-hydraulic proportional valve required large thrust drive,five structural forms of voice coil motor are proposed.Using the electromagnetic simulation tool ANSYS Maxwell,the thrust and magnetic field distribution characteristics of voice coil motors with different structures are calculated,and the effects of core radius and coil displacement on the thrust and magnetic field distribution of voice coil motors with different structures are analyzed.The results show that among the five structures,the internal magnetic type without iron core,the coil tightly attached to the shell,and the segmented design of the permanent magnet had the maximum thrust,reaching 75.29 N,which was verified through experiments;Adding magnetic rings on both sides of the permanent magnet and appropriately segmenting the permanent magnet can effectively enhance the thrust of the voice coil motor.
