Structure of air conditioner horizontal air deflector drive motor and circuit
Source: InternetPublisher:黄土马家 Keywords: Motor air conditioner CPU Updated: 2020/10/11
Shown is the structure of the air conditioner horizontal air deflector drive motor and circuit. The motor is a stepper motor. The drive signal is output by
the CPU @~@ pin and is amplified by IC702 to drive the motor. The fault can be identified by detecting the output signal of the CPU and the output signal of IC702 respectively
. The signal output by IC702 has the opposite phase to the output signal of the CPU . If there is a signal to drive but the motor does not rotate, the motor is
faulty: if there is no signal, check the power supply again. If the power supply is normal, the drive circuit is faulty.
