I'm interested in opinions on which type of motor and drive would
perform the best if your requirements are extremely smooth
rotation at low rpm (< 10). And, which feedback device could best
measure this "rotational smoothness" with accuracy. I have heard
of using frequency analysis to analyze velocity disruptions, but
I'm not sure how this could work. Right now this is just a "what
if" type of thing, so the motor does not even have to exist - yet.
Since the measurement of velocity is always going to be time-based,
does that introduce error into devices such as encoders, etc.?appreciate the input.
