Application solution
Humanoid Robotics Motion Platform
Humanoid robot OEMs requiring single-source supply for joint modules — combining hollow-shaft frameless motors, dual-encoder joint drivers, planetary-gearbox integrated joints, and linear actuators.
Single-source supply for humanoid robot joint modules. <em>Hollow-shaft frameless torque motors</em>, <em>integrated planetary-gearbox joints</em>, and <em>dual-encoder joint drivers</em> with EtherCAT/CANopen/CAN FD support. <em>≤1 µs multi-axis synchronization</em>, 8/16 kHz control loops, ≤10 arcmin gearbox backlash. Kinco collaborates with 100+ humanoid robotics OEMs worldwide.
The application demands · what we engineer
Motor Design
- Hollow-shaft frameless torque motors for rotating joints
- Precision coiled winding for lower copper loss
- Ultra-thin slot insulation, high-flux-density electrical steel
Joint Driver
- EtherCAT (CoE per CiA402 with CSP/CSV/CST modes), CANopen, CAN FD support
- Distributed Clock with ≤1 µs multi-axis sync jitter
- Control loops: 8 kHz position, 16 kHz velocity & current
Gearbox & Encoder
- Planetary gearbox with ≤10 arcmin backlash
- Full grinding process for GB5 grade accuracy; gear skiving for GB6
- Lower starting torque, 30K lower steady-state temperature rise
System architecture
Controller → HUMANOID JOINTS components over a shared control / motion bus. Derived from the recommended BOM.

Candidate BOM, subject to engineering review. Kinco performance and installed-base figures reflect the manufacturer's product portfolio. Trademarks belong to their respective owners.
What we engineered & validated
Joint sizing driven by required peak torque, continuous torque, range of motion, and ambient temperature.
EtherCAT recommended over CANopen when multi-axis sync jitter must be ≤1µs.
EtherCAT topology with distributed clock enabled for multi-axis sync
OEMs sourcing motor / drive / gearbox separately may need mechanical re-design for integrated joint envelope.

Frequently asked
How many humanoid robotics OEMs does Kinco currently support?
Per Kinco's 2026 published material, they collaborate with 100+ humanoid robotics companies worldwide (source: Kinco humanoid robotics newsletter). Specific OEM relationships and case studies are subject to NDA.
What's the manufacturing capacity for joint modules?
Kinco operates a dedicated facility producing 500K+ joint motors/joints annually (source: Kinco humanoid robotics newsletter). Capacity scaling is part of Kinco's published strategic roadmap.
What multi-axis synchronization accuracy is achievable?
Kinco's joint driver supports EtherCAT Distributed Clock with multi-axis synchronization jitter of ≤1 µs (source: Kinco published technical material). Actual achieved sync depends on full chain implementation (master, network topology, end-device clocks).
What we are
An independent engineering & sourcing partner. We architect the humanoid joints stack, select and integrate the BOM across supplier lines, and validate the system before you commit.
Where it does not fit
Robots requiring proprietary actuator types not in Kinco's portfolio (e.g., hydraulic, pneumatic muscles) Component certifications are per datasheet; system-level certification of your finished machine remains the integrator's responsibility, subject to engineering review.
How this solution is delivered
You describe the application, program or BOM; we confirm what the service covers — and what it does not.
An engineer reviews materials against our supplied lines and flags risks and limits.
You receive a scoped work plan with deliverables and boundaries — before any commitment.
Work is delivered against the agreed scope, with documentation and hand-off.
