AI Technical Summary
Technical Problem
The problem of damage to the motor drive circuit and electronic brake function circuit due to mutual interference between the brake signal and the drive signal.
Method used
By setting up a first and second unidirectional switching transistor group, the braking signal and the drive signal are isolated. Combined with a delay module to prevent signal interference, this ensures that the motor does not brake suddenly when it is driving normally.
Benefits of technology
This effectively avoids damage to the motor drive circuit and electronic brake function circuit, achieving reliable braking of the motor and preventing accidental rotation.
