The Design and Analysis of the Actuator with Long Stroke and Micro-Displacement

Abstract:

In this paper, a new actuator with nanoscale micro-displacement is reported. The actuator not only can achieve a large stroke and nanoscale positioning accuracy, but also has the advantages of compact, low cost, high reliability and a single control system. The drive is controlled by a single power, and it consists of stepper motor, harmonic gear reducer, screw and the guide rail. The stepper motor is controlled by the pulse train and the harmonic gear reducer has high precision and small hysteresis. The precision screw converts the rotary motion of the stepper motor into linear displacement, and the plunger pushes the target in nanoscale motion accuracy through the guide rail finally.
