EYOU PHA11H-101-C Harmonic-Drive Robotic Joint Actuator, 101 Reduction, CANopen, Humanoid Robots

Overview

The EYOU PHA11H-101-C is a harmonic-drive robotic joint actuator with a 101 reduction ratio, built-in driver, and CANopen communication. It operates from 2448 VDC and uses dual absolute 16-bit encoders on the motor and reducer sides. Its 52 55.5 mm form factor, 0.375 kg weight, and 6 mm hollow diameter support integration into humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots.

Features

• Harmonic reducer with a 101 reduction ratio.
• Built-in driver with CANFD input/output and CANopen communication.
• Dual absolute encoders: 16-bit motor side and 16-bit reducer side.
• Supports Profile Position (PP), Profile Velocity (PV), Profile Torque (PT), Cyclic Synchronous Position (CSP), Cyclic Synchronous Velocity (CSV), and other control modes.
• Matte black anodized housing and blackened reducer outer ring.

Product Views

The PHA11H-101-C is labeled as an EYOU ProServo-HA11H actuator. The PHA11H-101-C has a yellow rectangular multi-contact connector.

Features and Design

The PHA series is described as a lightweight harmonic drive robot actuator.The actuator is described as using new reducer materials and structural optimization to reduce weight in key parts while maintaining strength and load capacity. The lightweight design is stated to improve robot motion agility and dynamic response, support further system weight reduction, and extend battery life.The design is stated to lower steady-state temperature rise by 2C under the same conditions. A thermal-simulation-optimized design and black anodized surface finish are stated to improve heat-radiation efficiency.Mass power density is stated to rise by an average of 25%, delivering stronger output at similar or lighter weight. Torque ripple is stated to be below 5% for smoother, quieter operation.

Application Examples

The actuator is presented for humanoid robot joint applications.
