Product Description


SYHG-V Series Harmonic Drive
Integrated for Frameless Motors | Hollow Cable Routing | Dual Encoder Ready

Product Overview
The SYHG-V Series features a hollow, flanged, standard-structure flexspline. The input shaft allows direct mounting of a frameless motor, while the hollow low-speed shaft enables convenient cable routing through the center. Encoders can be installed on both the input and output sides. This design is ideally suited for collaborative robots (cobots) and integrated joint modules.

SYHG-V Series Harmonic Drives for Cobot Joints


Key Features

  • Hollow Cable Routing – Safe & Reliable
    Cables pass cleanly through the hollow low-speed shaft, simplifying cable management and reducing interference risks.

  • Space-Saving Joint Design
    Compact architecture reduces overall joint volume, enabling slimmer robot designs.

  • Frameless Motor Ready
    Input shaft designed for direct mounting of frameless motors – no additional adapter required.

  • Dual Encoder Mounting
    Encoders can be installed on both input and output sides for precise position feedback and advanced safety functions.

  • Minimal Runout on Motor & Encoder Mounting Surfaces
    Low runout ensures accurate alignment and consistent performance.

  • Zero Backlash
    Eliminates lost motion for smooth, precise control.

  • High Positioning & Rotational Accuracy
    Delivers excellent angular precision and repeatability for demanding motion tasks.

Typical Applications

  • Collaborative Robots (Cobots) – Direct integration into joint modules

  • Integrated Joint Modules – Compact actuation with built-in sensing

  • Humanoid Robots – Space-constrained, cable-friendly joints

  • Medical & Rehabilitation Robotics – Safe, reliable hollow routing
