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.
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.
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.
Interface Drawings and Engineering Files
Request model-level STEP files and datasheets through the engineering resource workflow to ensure revision consistency.
