How to Choose a Small Harmonic Actuator?

Sep 20, 2026

Small harmonic actuators are known for their compact size and high performance. They are commonly used in semiconductor equipment, 3C automation, laser equipment, CNC machine tools, and other precision automation applications. So, how should you select a small harmonic actuator for your application?

Hello everyone, I’m Theodore Li, Technical Director at HONPINE. Today, I will introduce HONPINE’s Series 11 small-size rotary actuators and their key configuration options.

Hollow or Solid Shaft Configuration

HONPINE Series 11 rotary actuators can be flexibly configured with either a hollow shaft or a solid shaft, depending on the specific requirements of the application.
