| Research Abstract |
In this study, a compact linear stepping actuator with ultra-fine resolution over a one-millimeter stroke (millimeter-stroke) is designed and fabricated by integrating a coaxial differential ball screw with a stepping motor. The performance of the fabricated actuator is evaluated experimentally, and a method of error compensation is devised and applied to this actuation system. Consequently, ultra-precise linear stepping actuator is realized with travel deviation of less than 0.06 microns (RMS) and with fine positioning resolution of 5 nm.
