Details

MG8015E-i9-V3 combines a high-torque motor and planetary reducer in a compact joint-ready package for automation.

Pair the motor with an FOC drive option supporting 12–60V input and RS485 or CAN bus control for easy integration.

Dual absolute encoders on the motor and reducer help retain position reference and support repeatable joint control after power-off.

Clear pin mapping and dual temperature-sensor inputs simplify wiring and enable real-time thermal monitoring.

A 1:9 planetary reducer with low backlash supports smooth motion and stable torque output for robotic joints.

Motor tool software supports parameter tuning, testing, and firmware upgrades during setup and commissioning.

Multiple control modes plus protection features and brake commands support flexible motion control strategies.

Designed for robotics and mobility platforms such as AGVs, robot arms, quadrupeds, and wearable robots.
