Overview

The EYOU RP70L is a planetary robot joint actuator with a 20:1 reduction ratio, 48 VDC operating voltage, built-in FOC drive, and CANopen/CAN FD communication capability. It is specified for robotic applications including humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots. The module provides 12 N·m rated torque, 36 N·m peak torque, and output speeds up to 160 rpm.

Features

Planetary reducer with a 20:1 reduction ratio.
Built-in FOC drive with current, speed, position, and MIT control modes.
Dual absolute encoder: 17-bit input and 19-bit output.
Power DC input/DC output and CAN FD input/output interfaces.
Crossed roller bearing and a 6 mm hollow diameter.
Regular matte-black shell finish.
