Advice on wiring Brushess DC motor, FIT0441

I need some wisdom,

I have a brushless DC motor, 159RM Fit0441, as per link below.

I would like to conect to a 12 power supply and ESP32 Wroom dev board.

I have wired up to board and power as per WIKI

with power -ve to board.

(FG not connected as waiting on resistor) but this should not be need to get motor to turn ?

however the motor does not turn.

My understanding is that with 12v applied, and a 3.3 volt feed to PWM ( wire 1) it should ?

Any advice good.
Or if you can suggest another way to run motor from 12v power adaptor, (speed control good, but not complusory)

Thanks

James

Hi James

The example seems to be centred around Arduino UNO which is probably a 5V PWM signal. So 3.3V might not be enough.

And the controller might be expecting a PWM signal, not a steady DC. Don’t know for sure as I am not very familiar with brushless drive controller details. I must do some research on this as this technology seems to be the go these days.
