will I have to had an encoder
What if I supply one coil with a low (or very low current), I'd be able to turn it with hands.
Does the sytem sees any different between coil beeing face and static to the right magnet or not and still static? or does he sees any difference only when moving BEMF (like the sensorless brushless motor)?
I recognize most of those words, but not in that order. Sorry.
... but if we still talk about knowing position of stepper - how to do it ?I think I really need this ability..
