Briefing
Detailed
MG8108-36 Integrated Robot Joint Motor
Achieving high torque output, precise position control, and excellent dynamic response performance within a compact structure. It supports position control, velocity control, torque control, and MIT hybrid control modes, meeting the motion control requirements of multi-degree-of-freedom robot joints under high-load, low-speed, and high-precision operating conditions.
Engineered for Precision Motion
Feature – Integrated All-in-One Design
The MG8108-36 integrates a BLDC servo motor, 36:1 planetary gearbox, drive electronics, and dual encoders in a singleØ96*57mm housing. This eliminates the need for separate component sourcing, wiring, and tuning.
Advantage – Reduced System Complexity
By combining motor, gearbox, driver, and encoder into one module, engineers can cut development time by up to 60% and simplify overall system architecture significantly.
Benefit – Faster Time to Market
With plug-and-play integration, R&D teams can focus on application-level development rather than motor control, accelerating robot prototyping and production ramp-up.
Feature – High Torque Density
Rated output torque of 32.76N·m with peak stall torque reaching 109.50N·m. The 36：1 planetary gearbox delivers exceptional torque density in a compact form factor.
Advantage – Superior Dynamic Performance
High torque-to-weight ratio enables faster acceleration, smoother motion, and greater load capacity — critical for responsive robot joint movement.
Benefit – Handles Demanding Applications
Suitable for humanoid robots, collaborative robots, and exoskeletons where high torque and compact size are essential for natural, powerful motion.
Feature – Dual Encoder Feedback & IP54 Protection
Built-in 14-bit high-resolution encoder with support for secondary encoder feedback on the output shaft. IP54-rated sealed housing protects against dust and water splashes.
Advantage – Precision & Reliability
Dual-loop feedback ensures accurate position, speed, and torque control. IP54 enables deployment in harsh industrial environments without performance degradation.
Benefit – Long-Term Operational Stability
Reliable feedback and environmental protection reduce maintenance needs and ensure consistent performance over extended operating periods.
