Overview

The EYOU RHU20L-70 is a harmonic-drive robot joint actuator for humanoid robot applications. It combines a 180 W motor, built-in driver, dual absolute encoder, and 48 VDC rated operation in a Φ70 × 68 mm module. Select 50, 80, or 100 reduction ratios and a brake or no-brake version to suit the required output torque, speed, and integration arrangement.

Features

Harmonic reducer with a built-in driver.
Dual absolute encoder: motor side 17 Bit and reducer side 19 Bit.
Driver interfaces: Power (DC in DC out), CAN FD (In,Out), EtherCAT (In,Out), and STO (1,2).
EtherCAT and CANopen communication protocols.
Control modes: Profile Position (PP), Profile Velocity (PV), Profile Torque (PT), Cyclic Synchronous Position (CSP), Cyclic Synchronous Velocity (CSV), etc.
Brake options: With Brake or Without Brake.
