I don't remember the details but remember a size 34 stepper on the bench here running somewhat above 3k rpm. It required low accel but you could control it getting up to speed. Motor inertia made it really difficult to slow down while maintaining position -- impossible to do any useful work with it. The torque curve on steppers drops off quickly as you turn them faster. Position feedback doesn't help much.
