Controlling speed of EDF motor

[Theboel]

Hi

I am looking for advice on how to control the speed of EDF motor without using the remote control, I need to control the speed based on pressure. (0,4 bar)
any help will apreciate.

Thank You
Anton

Hook up a I2C pressure sensor IC to a microcontroller then have the microcontroller generate the PWM servo signal to drive the throttle of the motor controller.

Hi Berni,

Thank you for suggestion I start looking for an Arduino project.

Buy the recommended BLDC motor controller as shown on the web page, and generate a 1...2 ms PWM pulse with 20 ms repetition rate from your microcontroller.
Getting the PID loop right is probably going to be the most difficult part.

and to clarify things. 1ms is low throttle or off. 2ms pulse is full throttle or fully on. and please keep fingers out of the spinning blades of death while on
