With the working principle of the air door actuator of the automobile air conditioning, the application of the air door system of the automobile air conditioning is more and more common, and becomes a key component of the passenger car comfort, it can adjust gas temperature, ambient humidity, cleanliness, exhaust volume and wind frequency to ensure passengers in a comfortable natural gas environment under various external climate and standards, as a key component of the air conditioning drive mechanism, the actuator is the tail part of the Electric Control Command of the air conditioner, and the stepper motor is a very important structure. At present, the stepper motor of the air-conditioning damper actuator is divided into two parts, the upper shell and the lower shell. When the stepper motor is installed, a part of the upper and lower shells should be installed with coaxial output, but the axial force between the upper and lower shells is not big during the whole installation, which endangers the use of the stepper motor.The working principle of the air-conditioning Valve actuator the working principle of the air-conditioning Valve actuator the knowledge actuator of the Mechanical Motor pump valve is an essential part of the air-conditioning components of the automobile, the key is used to control different automotive air conditioning intake valve opening or closing. The actuator is connected to the air conditioning wind direction selector knob in the cab of the vehicle. The rotation of the motor is the key component of the actuator. According to the rotation of the motor, the lever is connected with the intake valve to make the different intake valve open or close. At present, the technical actuator connection means that the actuator lever immediately opens or closes the intake valve according to the support lever or rope. The connection is not smooth, easy to produce in-situ stress and Torque, easy to cause the rope fracture or support rod fracture. General throttle actuator is based on the micro-motor drive system to drive the gear reduction, and then drive the output drive gear rotation, output a certain speed ratio and Torque to drive the system arm. The rotating part is operated according to a spring brush mounted on the output transmission gear. The Spring Brush portion of the Circuit Board determines the angle of view. There are usually three types of control loops. One is operated by a drive system integrated chip, the motor is mainly used in the throttle mode, the other is to use the feedback working voltage to clearly output the driving gear rotation position, the control panel feedback the operating angle according to the working voltage value of the spring brush. This type of motor is usually used for mode or temperature dampers, while this type of motor is usually used for new return dampers.
