EtherCAT motor RMD-X12-P20-320-E

Buy high precision EtherCAT servo motor RMD-X12-P20-320-E for robotic systems and advanced drones

This integrated planetary servo drive from the Chinese brand MyActuator combines a brushless motor, a high-precision gearbox, a dual absolute encoder and an integrated driver with EtherCAT and CAN BUS support in a compact package.. The RMD-X12-P20-320-E is designed for humanoid robots, walking platforms and robotic manipulators. It is also great for heavy cargo drones that require precise control of gimbals and actuators.

5 main advantages of the engine

• Peak torque of 320 Nm for handling the heaviest loads.
• Dual absolute encoder (17 bit input, 18 bit output) for <0.01° accuracy.
• EtherCAT and CAN BUS support for flexible integration into any system.
• Cross roller bearing at output for high rigidity and rotational accuracy.
• Compact weight of only 2.37 kg with high power density.

The built-in brushless motor creates torque. A planetary gearbox with a gear ratio of 20 increases force and reduces speed to a nominal 100 rpm. Dual anchors track the input and output position of the gearbox, providing control accuracy down to 0.01 degrees. The built-in driver processes commands via EtherCAT or CAN BUS, adjusts PID and transmits telemetry. The output cross-roller bearing can withstand axial loads up to 4.5 kN and radial loads up to 5 kN.
