Details

MG4005E-i10-V3 combines a brushless motor with a planetary reducer in a compact form for robotic joints and automation axes.

Dual single-turn absolute magnetic encoders provide motor-side and output-side feedback, with a dedicated ID switch for bus setups.

Wiring is simplified with clearly defined terminals for power, RS485/CAN communication, and UART signal connections.

A brushless motor, precision planetary gearing, and FOC control support smooth torque delivery and accurate motion control.

The drive supports RS485 or CAN communication and a wide input voltage range (7.4–32V) for flexible integration.

PC software allows parameter tuning, functional testing, and firmware upgrades during commissioning and maintenance.

Choose from multiple control modes such as torque, speed, and position control, with built-in protection status monitoring.

Designed for compact actuation in mobile robots, articulated arms, quadrupeds, and wearable robotics.
