DC Drive Feedback Selection

QUESTION: DC Drive Feedback Selection

My question is how do you determine the best DC drive feedback for your application. Is armature feedback good enough for most variable speed applications? I'm not positioning anything, I am driving a narrow strip of metal through a punching machine at various speeds.

DC Drive Feedback Selection

I know this is an old post but for your application I would try armature voltage feedback first. See if it appears stable, and put a clamp on ammeter on it. Let us know how you made out.
