EYOU PHU25H-110 Harmonic Drive Robot Joint Actuator, 48 VDC EtherCAT/CANopen for Robotics

Overview

The EYOU PHU25H-110 is a harmonic-drive robot joint actuator with a built-in driver, 48 VDC rated operating voltage, and EtherCAT/CANopen communication. Selectable reduction ratios of 81, 101, and 121 provide distinct output speed, torque, and inertia values. Brake and non-brake selections are available for robotics applications including humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots.

Features

• Harmonic reducer with a built-in driver.
• 48 VDC rated operating voltage; 2448 VDC operating voltage range.
• Dual absolute encoders: motor side 19-bit and reducer side 19-bit.
• Power (DC in/DC out), CAN FD (in/out), EtherCAT (in/out), and STO (1, 2) driver interfaces.
• EtherCAT and CANopen communication protocols, with software-configurable protocol selection.
• Supported control modes: Profile Position (PP), Profile Velocity (PV), Profile Torque (PT), Cyclic Synchronous Position (CSP), Cyclic Synchronous Velocity (CSV), etc.
• Split-body architecture separating the motor and reducer; the PHU series is described as offering optional force-control function modules.
• Select either With Brake or Without Brake; the specification table identifies brake configuration values as B/N.

Applications

• Humanoid robots
• Robotic arms
• Exoskeletons
• Quadruped robots
• AGV vehicles
• ARU robots
• Industrial automation and heavy-duty robot applications
• Collaborative robotic arms
