Harmonic Drive RSF
Harmonic Drive RSF
Harmonic Drive RSF solid-shaft servo actuators combine a brushless motor, reduction gear and incremental feedback. The standard RSF, RSF-Mini and RSF-Supermini ranges cover distinctly different sizes and operating points; they should be selected as specific actuator configurations with a compatible external servo drive.
Review Summary
RSF is useful when a motor-and-gear assembly with a supported output shaft fits the machine better than independently assembled motion components. The central selection task is choosing the correct range and ratio. Rated torque, continuous limits, momentary peaks and output-equivalent encoder counts must stay attached to their exact model.
