摘　　要：电液伺服阀作为液压伺服控制元件中的核心元件,能将微弱信号转换为大功率信号,力矩马达作为电液伺服阀的核心元件,其性能直接影响电液伺服阀的性能。为了分析力矩马达输出转矩的影响因素,基于AMESim搭建仿真平台对各个因素进行分析,结果表明,永磁体剩余磁化强度、衔铁中心到衔铁末段距离、气隙处磁极面积和线圈匝数对力矩马达输出转矩影响较大,永磁体的长度以及横截面积和衔铁处于中位时气隙长度对力矩马达输出转矩影响较小,并通过试验验证了其正确性。As the core component of hydraulic servo control components,electro-hydraulic servo valve can convert weak signals into high-power signals.Torque motor as the core component of electro-hydraulic servo valve,its performance will directly affect the performance of electro-hydraulic servo valve.In order to analyze the influencing factors of the torque motor's output torque,a simulation platform was built based on AMESim to analyze various factors.The residual magnetization of the permanent magnet,the distance from the center of the armature to the end of the armature,the magnetic pole area at the air gap and the number of coil turns have a greater influence on the output torque of the torque motor.The length and cross-sectional area of the permanent magnet and the armature are in the neutral position.The air gap length has little effect on the output torque of the torque motor,and compared with experiments to verify its correctness.
