Product Overview

A06B‑2055‑B103 is FANUC αi‑B series AC servo motor, widely applied for CNC machine‑tool axis drive, automation equipment and robotics. High‑resolution built‑in rotary encoder provides precise position and speed feedback for closed‑loop motion control. Compact mechanical structure delivers high torque‑density performance. Spare motor available as refurbished and surplus tested units for CNC‑equipment repair and retrofit projects.

Application Notes

‑ Match motor parameter inside FANUC servo‑drive parameters. ‑ Shielded power and encoder cables are required. ‑ Avoid mechanical shaft over‑load beyond motor rated torque. ‑ Typical deployment: CNC‑machine‑tool servo‑motor spare‑part stocking.
