In this paper, a comprehensive theoretical analysis of servo valve torque motor that includes the ignored magnetic reluctance of magnetic elements is carried out. These analyses are based on fundamental laws of electromagnetism and general mechanics, thus a new mathematical model of servo valve torque motor is derived to improve the accuracy of the model. When using this model structure to fit the simulation data of electromagnetic torque constant and magnetic spring stiffness, the result render closer agreement with than when using existing models. |
