Details

The MG4010E-i36-V3 combines a brushless motor, planetary reducer, and magnetic encoder for compact robotic actuators.

A flange-style output end and fixed end layout makes integration easier in arms, legs, and other joint modules.

RS485 or CAN communication pairs with an FOC driver and absolute magnetic encoder feedback for stable torque, speed, and position control.

Common use cases include AGVs, robotic arms, quadruped platforms, exoskeletons, and inspection or service robots.

Wiring is simplified with labeled RS485/CAN bus pins, power connections, UART Tx/Rx, signal ground, and an onboard ID switch.


Built-in brake control and multiple operating modes help tune behavior for different motion-control tasks and safety requirements.
