摘要
In view of the influence of the electromagnetic characteristics of the torque motor of the twin flapper-nozzle electro- hydraulic servo valve on the response of the armature response,the finite element technique and CST software were used to establish the torque motor electromagnetic characteristics simulation model.The electromagnetic characteristics of torque motor with different coil turns and different thickness of magnetic fluid layer were studied under the condition of basic components and adding magnetic fluid in the torque motor.Research results show that the magnetic fluid introduced into the torque motor or increasing the number of turns can increase the armature electromagnetic force and improve the torque motor electromagnetic performance under the same current condition. © 2019, Editorial Board of Journal of Huazhong University of Science and Technology.
