EYOU PHU11H-52 Harmonic Drive Robot Actuator, 51/101 Ratios for Robotics

Overview

The EYOU PHU11H-52 is a harmonic-drive robot actuator with a built-in driver, 48 VDC rated operation, dual 19-bit absolute encoders, and 51 or 101 reduction-ratio options. Choose a With Brake or Without Brake configuration to suit the application. The actuator supports EtherCAT and CANopen communication and is specified for robotics and automation scenarios including humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots.

Features

• Harmonic reducer with a split-body design that separates the motor and reducer.
• Built-in driver and dual absolute encoders: motor side 19-bit and reducer side 19-bit.
• EtherCAT and CANopen communication protocols; software-configurable protocol switching is indicated for the PHU series.
• Control modes: Profile Position (PP), Profile Velocity (PV), Profile Torque (PT), Cyclic Synchronous Position (CSP), Cyclic Synchronous Velocity (CSV), and others.
• Selectable 51 or 101 reduction ratios, which provide different speed and torque profiles.
• Selectable With Brake or Without Brake configuration; the With Brake option corresponds to an optional brake module.

Product Views

The product is labeled PHU11H-52. The connector-end view shows two gold-colored high-current connectors and three small rectangular connectors.PHU is identified as an enhanced harmonic drive robot actuator series.

Application Examples

The PHU series is built for industrial automation and heavy-duty robot applications. The PHU series uses a split-body architecture intended to improve production consistency and ease maintenance while maintaining high precision and high power density.Humanoid robot torso with visible shoulder jointArticulated collaborative robotic arm

Options and Model Comparison

The With Brake option corresponds to the PHU series’ optional brake module. PHU series modular configuration supports optional brake and force-control function modules for robot-platform adaptation and system integration.

Features and Design

The split-body design separates the motor from the reducer. Reducers with different ratios can be paired with the same motor to provide different speed and torque profiles.

Interfaces and Connections

The PHU actuator supports CANopen and EtherCAT protocols, switchable through software configuration.
