The A06B‑0215‑B000 αiS4/5000 AC servo motor belongs to Fanuc’s αiS4/5000 series, a high‑torque, high‑speed generation of Fanuc servo motors intended for CNC machining centers, turning machines, and multi‑axis automation cells. It is a 3‑phase AC brushless synchronous motor engineered for high‑duty, high‑acceleration applications that demand precise positioning and smooth speed control.
This Fanuc servo motor is rated for approximately 1 kW continuous output at ≈4000 RPM with a maximum speed of 5000 RPM, and a stall torque of 4 Nm, providing strong acceleration and holding capability without excessive inertia. The tapered shaft (TPR) design enables simple, rigid coupling and easy mounting, while the no‑brake configuration helps reduce cost and weight for applications where external holding measures are acceptable.
Physically, the A06B‑0215‑B000 is built with IP65‑standard seals, sealed bearings, and robust housing, suitable for industrial workshop environments exposed to dust, vibration, and moderate coolant exposure. The motor integrates an αi/A1000 / iA1000‑style encoder for high‑resolution feedback, ensuring tight coordination with Fanuc αiS‑series amplifiers and CNC controllers. It is typically supplied with 1‑year warranty for new units and is widely used in small‑ to medium‑sized CNC machines where compact, high‑performance servo drives are required.
