Working principle of fine small multi-turn electric actuator

Date:Aug 12, 2019

The intelligent controller of the multi-turn intelligent electric actuator, which accepts the standard analog current control signal or the switching volume control signal, and compares with the position signal of the valve position sensor, positions the output axis of the actuator in the corresponding position with the input signal, complete the positioning control, and can control according to interlocking. Two-line control or time signal is positioned in the pre-set position of the control system, unless the output shaft torque value of the actuator occurs during operation is greater than the rated torque value or set torque value, the intelligent controller of the actuator will meet the requirements of the control system, issue the correct instructions, trigger the three-phase solid state relay, so that the motor is connected to the three-phase power supply, drive the actuator to run normally.
