Harmonic Rotary Actuator for High Precision Positioning: What Really Determines Positioning Accuracy?
Positioning accuracy depends on the entire motion system, not just the harmonic reducer.
This article explains the key factors that determine the positioning accuracy of a harmonic rotary actuator, highlighting why low backlash and high encoder resolution alone cannot guarantee precise motion. It explores the roles of torsional stiffness, encoder feedback architecture, load inertia, bearing support, servo tuning and mechanical installation, and provides practical guidance for selecting an actuator based on actual application requirements. Integrated and hollow-shaft actuator designs are also discussed as ways to simplify system integration and support high-precision positioning in robotics, semiconductor equipment and industrial automation.
