Brushless Air Fan Reverse Turn
Budget: $10 – $30 CAD
I have a 12V brushless air fan that operates at 0.7A and has four wires:
Red – +12V
Black – GND
Yellow – PWM Speed Control
Purple – Feedback
The manufacturer informed me that to reverse the fan’s rotation, I need to send a signal to the PWM (yellow) wire.
Could you please guide me on how to generate the correct PWM signal to achieve a reverse turn? Do I need a specific duty cycle, frequency, or additional control?
Thank you for your help!
