| Abstract: | A device was designed for durability test of air conditioner damper.The device used STM32F103RCT6 microcontroller as the system control core,included ACS712 current sensor acquisition circuit and full bridge drive circuit module RZ7899.The acquisition circuit collects the real-time current connected to the damper actuator motor,the output voltage determines the position of the damper,the feedback control system,and the drive circuit module realizes the start and stop of the damper at any position,to avoid being stuck due to the damper failure during the durability test,and the current suddenly increase the risk of damage to the motor.Using electric drive RZ7899,through the H-bridge control principle,realize the function of motor forward and reverse. |
