Overview
The EYOU PHU17H-80-F is a harmonic-drive robot actuator for robotics applications including humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots. Select a 50 or 100 reduction ratio and a With Brake or Without Brake configuration. It has a built-in driver, 48 VDC rated operating voltage, torque sensing, and CANopen/EtherCAT communication for motion-control integration.
Features
- Harmonic reducer with selectable 50 or 100 reduction ratio; the ratios provide different output speed and torque values.
- Brake selection: With Brake or Without Brake.
- Built-in driver with dual absolute encoders: motor side 19 bit and reducer side 19 bit.
- Communication protocols: EtherCAT and CANopen; protocol switching is supported through software configuration.
- Driver interfaces: power (DC in/DC out), CAN FD (In/Out), EtherCAT (In/Out), and STO (1, 2).
- PHU-series split-body architecture separates the motor and reducer. PHU-series materials describe independently produced and tested core components for tracking and control.
