Integrated Harmonic Joint Actuator

High-precision integrated actuator module with harmonic reducer, encoder, and compact servo drive interface for articulated robot joints.

Target Buyer:Best for teams prioritizing precision motion, compact form factor, and stable low-speed control.

Integrated harmonic joint actuator module

Capability Highlights

Zero-backlash harmonic reduction architecture
High positioning repeatability for fine path control
Compact envelope for shoulder, elbow, and wrist joints

Typical Applications

Humanoid upper-limb joints
Medical and lab automation axes
Precision assembly and inspection robots

Engineering Focus

Continuous vs peak torque sizing under duty cycle
Encoder resolution and closed-loop tuning strategy
Thermal margins at sustained low-speed high-load operation

Key Evaluation Matrix

Metric	Typical Range	Why It Matters
Backlash	< 0.1° (application dependent)	Backlash directly affects path repeatability and force-control smoothness.
Continuous Torque	5-80 Nm class	Defines sustained output before thermal derating in cyclic production.

Technical Specification Baseline

Use this baseline for first-pass engineering comparison before requesting model-specific files.

Field	Baseline Value	Interpretation Note
Supply Voltage	24-48V DC	Matched per control architecture and duty profile.
Continuous / Peak Torque	Project-dependent harmonic class	Finalized by duty cycle and thermal verification.
Max Speed (No-load reference)	Application-tuned	Validated against target trajectory and control stability.
Encoder Resolution	Multi-turn absolute (model dependent)	Specified in detailed model-level technical package.
Communication	EtherCAT / CAN options	Scope confirmed during RFQ and integration planning.

Performance Evidence

Detailed torque-speed envelopes and dynamic response evidence are provided in model-level engineering packages. Interpretation is tied to duty cycle, thermal constraints, and interface assumptions.

Torque-speed boundary interpretation is valid only with matched ambient and duty assumptions.
Response stability conclusions require controller and protocol scope alignment.
Final acceptance uses customer-approved sample validation criteria.

RFQ Checklist

Target joint axis and load inertia
Continuous / peak torque requirement at speed
Voltage, control mode, and protocol (EtherCAT/CAN)
Mechanical interface drawing and cable routing constraints

Risk Controls

Peak-only sizing causes thermal overload: Use duty-cycle-based continuous torque verification before sample lock.
Control jitter at low speed: Specify encoder resolution and loop bandwidth targets in the initial RFQ.
