Overview
The EYOU PHA08L-101-C is a harmonic-reducer motor module for robotic joint applications. The listed version has a 101:1 reduction ratio, built-in driver, CANopen communication, and dual absolute encoders with 16-bit motor-side and reducer-side resolution. It is rated for 24 VDC operation within a 24–36 VDC range and provides a 1.65 N·m rated output torque at 2000 rpm input.
Features
- Harmonic reducer with 101:1 reduction ratio.
- Built-in driver with CANFD input/output and power DC input/DC output interfaces.
- 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 outer-ring-blackened reducer finish.
