Overview

The MyActuator RMD-X4-36 Planetary Actuator DC Brushless Motor is a high-performance joint actuator designed for robotics and automation systems requiring precise motion control, high torque output, and compact integration. With a 34N·m peak torque, 36:1 gear ratio, and crossed roller bearing structure, it delivers excellent anti-bending capability and durability. Featuring EtherCAT + CAN dual communication protocols and a 250μs ultra-fast response, this actuator is ideal for humanoid robots, robotic arms, mobile platforms, and other advanced robotic applications. Its dual encoder design (ABS 17-bit input / 18-bit output) ensures ultra-high positioning accuracy, while the compact size (55mm × 61mm, 0.36kg) enables lightweight and efficient integration.

Key Features

• High Precision Dual Encoder: 17-bit (input) + 18-bit (output) for 0.01° accuracy.

• EtherCAT + CAN Bus Protocols: Flexible communication with 250μs ultra-fast response.

• Crossed Roller Bearings: Superior anti-bending performance and long service life.

• High Power Density: Compact 55mm diameter, 61mm length, and only 0.36kg weight.

• Peak Torque 34N·m and Rated Torque 11.5N·m ensure stable, powerful motion output.

• High Efficiency: 100W rated power with smooth FOC (Field-Oriented Control) technology.

• Versatile Application: Designed for humanoid robots, exoskeletons, manipulators, and automation systems.
