Overview
The EYOU PHA14H-101-C is a harmonic-drive robot joint actuator with a 101 reduction ratio, built-in driver, CANopen communication, and dual absolute 16-bit encoders. Designed for robotic joints, it provides 9.6 N·m rated torque at 2000 rpm input, 34 N·m peak output torque, and output speeds up to 33 rpm. The selected version is non-braked (N).
Features
- Built-in driver with power (DC in/DC out) and CAN FD (in/out) interfaces.
- CANopen communication protocol.
- Dual absolute encoders: motor side 16-bit and reducer side 16-bit.
- Control modes: Profile Position (PP), Profile Velocity (PV), Profile Torque (PT), Cyclic Synchronous Position (CSP), Cyclic Synchronous Velocity (CSV), etc.
- Harmonic reducer with a 101 reduction ratio.
- Non-braked configuration (B/N: N).
- Matte black anodized housing and blackened outer reducer ring.
