integrated joint module gear motor trends
**Integrated Joint Module Gear Motor Trend: Integrated Drive, Control, and Sensing, Reshaping Robot Joints**
Robot joints are moving from "building blocks" to "integrated modules." Motors, precision reducers, encoders,
brakes, and drivers are integrated into a compact unit, offering plug-and-play functionality and significantly
reducing overall design complexity and assembly time. By 2027,
integrated joint modules will become standard equipment for collaborative robots, humanoid robots, and service robots.
**Trend 1: High-Density Integration of Five-in-One or Even Six-in-One Units** Reducers (harmonic/RV/planetary),
torque motors, multi-turn absolute encoders, brakes, servo drives, and torque sensors are all encapsulated in an aluminum
alloy housing, requiring only external power and communication cables. The size is reduced by more
than 40% compared to discrete solutions, and wiring is reduced by 80%.
**Trend 2: Torque Density Race** Joint outer diameters are breaking through from 80mm
to 50mm and even below 40mm, while torque output continues to increase. The combination of coreless
motors, axial flux motors, and high-rigidity harmonic reducers allows for a torque output of over
80Nm per kilogram of weight. **Trend 3: Closed-Loop System and Intelligent Sensing
** The module incorporates temperature, vibration, position, and torque sensors to provide
real-time feedback on joint health. Combined with edge AI, it can autonomously detect collisions
and predict gear wear, enabling safe collaboration and predictive maintenance.
**Trend 4: Open Platform and Unified Protocols** EtherCAT and CANopen over EtherCAT (CoE)
have become mainstream communication protocols. Standardized mounting flanges and electrical interfaces
allow for interchangeability between modules from different manufacturers, reducing supply chain risks.
**Trend 5: Rapidly Decreasing Costs** Mature domestic harmonic and RV reducer technologies have
reduced the unit price of integrated modules from tens of thousands of yuan to several thousand yuan,
enabling mass adoption in cost-sensitive scenarios such as service robots and logistics AGVs.
