Abstract:A control circuit for the electric actuators is presented in this paper,where a chip with 4 independent operational amplifiers is used to form a differential amplifier with a high voltage gain and negitive feedback characteristic,and a protection circuit with positive feedback characteristic.The former is used for the comparison of the setting and the feedback,and also the amplification of their difference.The latter is used for over-torque protection.The circuit is small and of a high cost performance ratio.It also has the function of over-travel protection and over-torque protection.The circuit has been proved feasible in practice.
Keywords:electric actuator  controllor  operational amplifier  electrical protection
