Overview

The EYOU RP90L is a planetary robot joint module for humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots. It combines a 633 W motor with a 21.913 reduction ratio, 35 N·m rated torque, 120 N·m peak torque, built-in FOC drive, and dual absolute encoders. The module operates from 48 VDC ±10% and provides CANopen communication; CAN FD requires custom development.

Features

Planetary reducer with a 21.913 reduction ratio.
Built-in FOC drive.
Dual absolute encoders: 17-bit input and 19-bit output.
Crossed roller bearing.
Power interface with DC input and DC output, plus CAN FD input and output.
Control modes: current, speed, position, and MIT mode.
Regular matte-black shell finish.
