Electric motor control damper actuator

Electric motor control damper actuator – it has 3 phase induction motor its operate the lever this actuator has primary and secondary gear secondary gear also known as worm gear at front side there is indicator which shows the position of damper at the back side wheel and handle is given if we want to operate the actuator manually then push the handle clockwise this thing bypasses the motor now we can easily set the position of damper as per requirement through the wheel in this actuator there is an advantage that we can adjust the damper at 30% , 40% etc but in most pneumatic actuator(with single solenoid coil) we operates only either fully open or fully close condition

Electric motor damper actuator has 6 limit switch as described further

2 limit switch for full open (1 for retendency in case failure)

2 limit switch for full close condition (1 for retendency in case failure)

1 for open torque (when we open the damper for flow if there is obstruction like material jamming or some material struck around)

1 for close torque (when we close  the damper if there is obstruction like material jamming or some material struck around foreign material coming
