摘　　要：数字伺服阀是未来伺服阀发展的一个重要方向,其大多采用驱动机构直接驱动阀芯工作的方式,因此性能优良的驱动机构能很大程度上提升整阀的性能。给出了一种基于永磁同步电机和丝杠的新型数字伺服阀驱动机构,并对其进行了深入的理论、仿真分析和相应的模拟带载试验,其性能可满足大流量数字伺服阀的性能需求。Developing digital servo valve is an important direction for future development of the servo valve. Digital servo valves mostly adopt the way of drive mechanism driving valve core directly,so a good performance of the drive mechanism can largely improve performance of the valve. This study presents a new digital servo valve drive mechanism based on permanent magnet synchronous motor and screw,and carries on the deep theoretical analysis,simulation analysis and the corresponding load test verification. The performance of drive mechanism can meet requirements of digital servo valve in large flow.
