Overview

The EYOU RHU14L-52 is a 48 V harmonic-drive robot joint actuator for humanoid robot joints. It combines a harmonic reducer, built-in driver, and dual absolute encoder, with 50, 80, or 100 reduction-ratio options and with-brake or without-brake selections. EtherCAT and CANopen communication, multiple control modes, and compact 52 × 65 mm dimensions support integration into robot-joint designs.

Features

Harmonic reducer with a built-in driver.
Dual absolute encoder: motor side 17-bit and reducer side 19-bit.
48 VDC rated operating voltage; 24–48 VDC operating-voltage range.
EtherCAT and CANopen communication protocols.
Power (DC in/DC out), CAN FD (In/Out), EtherCAT (In/Out), and STO (1, 2) driver interfaces; see terminal model description.
Selectable 50, 80, and 100 reduction ratios, with brake and non-brake options.
Control modes: Profile Position (PP), Profile Velocity (PV), Profile Torque (PT), Cyclic Synchronous Position (CSP), Cyclic Synchronous Velocity (CSV), etc.
