Overview
The EYOU PHA17H-101-C is a harmonic-reducer robot joint motor with an integrated driver, 101 reduction ratio, CANopen communication, and CANFD in/out interface. It operates from 24–48 VDC and is specified for robotics applications including humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots. Its output ratings, Φ80 × 68 mm form factor, and 10.8 mm hollow diameter support joint-level selection.
Features
- Built-in driver with power (DC in/DC out) and CANFD (in/out) interfaces.
- Dual absolute encoder: motor side 16Bit and reducer side 16Bit.
- CANopen communication protocol.
- Control modes: Profile Position (PP), Profile Velocity (PV), Profile Torque (PT), Cyclic Synchronous Position (CSP), Cyclic Synchronous Velocity (CSV), etc.
- Connector end includes two yellow connectors and two smaller white ports.
