Introduction
Compact integrated harmonic drive rotary actuators combine a frameless inner-rotor torque motor, harmonic drive and high-resolution absolute encoder into a single compact rotary unit. The control electronics are typically mounted externally to deliver precise motion control while the integrated motor-reducer stack minimizes envelope and simplifies mechanical integration for industrial systems.

Key features

• High torque at low speed: rated torque range 4 N·m up to 1200 N·m and high peak torque for demanding loads.
• Compact integrated architecture: frameless torque motor embedded to reduce footprint and improve stiffness.
• Precision positioning: built-in high-resolution absolute encoder enables micron-level positioning and soft-landing; repeatability ≤10 arcsec on many variants.
• Low inertia and fast dynamic response: lightweight rotor and low-friction design for rapid acceleration/deceleration.
• Hollow-shaft availability: through-bore options from ø9 mm to ø50 mm for cables, feedthroughs or spindles.

Technical specifications (key ranges)

• Available models: series 11–58 (multiple frame sizes).
• Reduction ratios: 51, 81, 101, 121, 161 (model dependent).
• Torque: rated 4 N·m → 1200 N·m; peak up to ~1964 N·m (largest variants).
• Speed: rated typically 12–69 RPM; max typically 25–118 RPM (model dependent).
• Electrical: rated current ~0.62–17.9 A; peak current ~1.36–34 A (reference AC-220V in datasheet).
• Accuracy: unidirectional positioning down to ≤30 arcsec for high-end models; repeatability ≤10 arcsec.
• Mechanical: hollow shaft ø9–ø50 mm; mass without brake ~1.17–32 kg; diameters/lengths per model as specified in datasheet.

Typical applications

• Machine tool rotary and indexing tables for CNC systems.
• Precision medical devices and robotic surgical axes.
• 5-axis laser cutting systems and precision machining centers.
• Semiconductor handling, die-bonding and assembly equipment.

Integration & options
