Critical speed for a leadscrew
The critical speed is the speed that excites the natural frequency of the screw. For a steel leadscrew or steel ballscrew, the critical speed is approximately Furthermore the *running speed* for a leadscrew (or ball screw) is typically limited to, at most, 80% of the calculated critical speed. Constant *C* values for steel leadscrew or steel ballscrew, depending on the ends: C = for one ...
