Hi All!
I am currently trying to create a board to drive BLDC and Stepper motor at something around 30Amps, but I am having a lot of issues with noise on sensor bus.
I would like to know if some of you has tried using this kind of optocoupler ( PC817) to isolate the logic of the circuit from the Power part.
I am currently doing some experiments and it seems to handle quite fine the Arduino PWM frequency (the opto should be rated 80khz, so it should be ok on Arduino PWM).
But, since none of the board posted on this forum has optocouplers in it, I started to overthink.
Is this a good solution? Or something bad could happen? (something that I don’t know and I am not considering)
Here the Opto datasheet:
Thanks!
