Engineered for Precision Motion

Feature – Integrated All-in-One Design

The MG 3505-8 integrates a BLDC servo motor,8:1 planetary gearbox, drive electronics, and dual encoders in a single Ø43*28.8mm 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 0.67 N·m with peak stall torque reaching1.79 N·m. The8:1 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.
