Abstract

In this paper the dynamic characteristics of the armature assembly of torque motor in jet pipe electro-hydraulic is studied. The results show that the stiffness of armature assembly and feedback spring pole are the key parts which can be directly related to geometric and material parameters of torque motor. Therefore, improvement of the operating characteristics of torque motor through dynamic stiffness is developed.
