The A06B‑0123‑B575 α3/3000 AC servo motor belongs to Fanuc’s α3/3000 servo family, engineered for smooth, high‑speed, and high‑accuracy positioning in CNC machine tools, industrial robots, and automation cells. It is a 3‑phase AC brushless synchronous motor with sealed construction, offering excellent protection against dust, vibration, and light coolant exposure in typical workshop environments.
This Fanuc servo motor typically delivers ≈0.9–1.1 kW continuous power at 127 V, 200 Hz, with a rated speed of ≈3000 RPM and a 3 Nm stall torque, providing strong acceleration and stable torque for feed axes and robot‑peripheral drives. The straight shaft configuration simplifies coupling and gearbox integration, while the fully enclosed structure reduces cable complexity and installation cost by allowing compact, on‑site mounting.
Physically, the A06B‑0123‑B575 is built with sealed housings and epoxy‑coated windings, making it suitable for more demanding atmospheric conditions than standard varnish‑insulated windings. The motor integrates an Alpha‑series encoder (A64 / α64‑style) for high‑resolution feedback that pairs seamlessly with Fanuc α3/3000 amplifiers and CNC controllers. It is commonly used in robotic arms, CNC lathes, milling machines, and material‑handling systems, where precise, repeatable motion is essential.
