Advances in Precision Motorized Positioning Systems: Selection Criteria
rage is feasible. Advantages are the compact size, self-locking design, and high holding forces (100N) compared to the size. Drawbacks are the slow speed – making the drive a good option for motion control [...] opto-mechanical equipment, and a great choice for replacing mechanical micrometers.
