| Abstract: | To achieving better control of the electro-pneumatic valve positioner,according to the action principle of torque motor,theoretical analysis was adopted to analyze the relationship of the output torque and fluxa of the new type of torque motor,and the relationship between input voltage and flux was analyzed.On this basis,the magnetic circuit model and circuit model of the torque motor were established.Finally the transfer function was established based on the angle of rotation of the torque motor movable iron and the input voltage.Simulations results show the correctness of the presented models. |
