The Working Principle Of Car Air Conditioner Damper Actuator

The application of automotive air-conditioning damper systems is becoming more and more common, and it has become a key component of passenger car comfort. It can adjust gas temperature, ambient humidity, cleanliness, exhaust volume and wind frequency to ensure that passengers are in various external climates and standards. In a comfortable natural gas environment, as a key component of the air-conditioning drive mechanism, the actuator is the tail of the air-conditioning electronic control command, and the stepping motor is a very important structure.

At present, the stepper motor of the Air Actuato mechanism of the air conditioner is divided into two parts: the upper casing and the lower casing. When the stepper motor is installed, part of the upper and lower casings should be installed with coaxial output, but the axial force between the upper and lower casings during the entire installation process is not large, which endangers the use of the stepper motor.

The working principle of the air-conditioning damper actuator is the working principle of the car air conditioner, the working principle of the air valve actuator. The key is to control the opening or closing of the intake valves of different automotive air conditioners. The actuator is connected to the air-conditioning and air-direction selection knob of the car cab. The rotation of the motor is a key component of the actuator. According to the rotation of the motor, the lever is connected to the intake valve to open or close different intake valves.

Currently, the technical actuator linkage is an actuator lever that instantly opens or closes the intake valve according to a support rod or rope. If the connection is not smooth, it is easy to generate ground stress and torque, and it is easy to cause the rope to break or the support rod to break. Generally, the throttle actuator is mainly used in the micro-motor drive system to attract the freight wheel to decelerate, then drive the output transmission gear to rotate, and output a certain speed ratio and torque to move the system arm. The rotating part operates according to the spring brush installed on the output transmission gear, and the arrow brush part on the circuit board determines the rotation angle.

There are generally three control loops. One is operated by the integrated chip of the transmission system. This motor is mainly used for the damper mode. The other is to use the feedback working voltage to clearly output the rotational position of the drive gear. This type of motor is often used for mode or temperature dampers, and this type of motor is often used for new return dampers.
