The integrated intelligent electric actuator adopts advanced intelligent digital control technology, which can directly receive 4~20mA DC signals from industrial control instruments or computer outputs without additional feedback unit and servo amplifier. It enables accurate position control of various industrial ball valves, disc valves, dampers, baffles, couplings, etc. This product not only improves the accuracy of the position control of the electric actuator, but also realizes miniaturization, intelligence, and integration (the controller and the actuator are integrated). Compared with the traditional electric actuator, it has the characteristics of small size, light weight, high precision, strong function, reliable performance, low running cost and no maintenance.Working principle and structure :Comparing the input signal from the control unit(4~20mA DC/1~5V DC) with the position feedback signal from the potentiometer,Drive the motor in the direction of eliminating the deviation,Stop at the set position of the input signal. The drive motor rotates through the spur gear to the worm and worm gear,When the motor rotates in the positive or negative direction,The output shaft rotates clockwise or counterclockwise,The movement of the output shaft is transmitted through the gear to the potentiometer with clearance compensation,The opening position is detected and fed back to the control unit.Through the above process, the purpose of controlling the output shaft position or the angular displacement according to the size of the input signal is realized.
