The function of the airflow damper motor is to drive the gear train to decelerate through the micro motor, and then drive the output gear to rotate, output a certain speed and torque to drive the rocker arm, and the rotation position is controlled by the spring brush assembled on the output gear, and the spring brush is on the circuit board. The position on determines the angle of rotation.
The common damper actuator mainly drives the gear train to decelerate through the micro motor, and then drives the output gear to rotate, and outputs a certain speed and torque to drive the rocker arm. Its rotation position is controlled by a brush mounted on the output gear, and the position of the brush on the circuit board determines the rotation angle. Generally, there are three control circuits, one is controlled by the driver chip, such as 8050P, this The motor is mainly used on the mode damper; one is to determine the rotation position of the output gear by the feedback voltage. In this way, the circuit board has a carbon film, and the panel controls the angle through the voltage value fed back by the brush. This kind of motor generally It is used in the mode or temperature damper, and the other is to control the 2 limit points directly through the on-off of the copper film and the spring brush. This kind of motor is generally used on the new return air damper.
Troubleshooting of air-conditioning damper motor: It is likely to be caused by the failure and damage of the air-conditioning airflow damper servo motor. According to the analysis of previous maintenance cases, the damage of the air-conditioning airflow damper motor is generally caused by the following two reasons:
One is caused by its own poor quality, and the other is caused by the excessive load of the airflow control damper due to stuck operation or excessive running resistance. If it is caused by the damage of the air-conditioning air damper servo motor, the only way to replace the damaged air-conditioning air damper servo motor is to replace the damaged air-conditioning air damper servo motor.
