The A06B‑0085‑B403 BiS22/2000 AC servo motor belongs to the Fanuc BiS series (often called Beta iS / BiS22), engineered for high‑torque, high‑duty feed‑axis and spindle‑peripheral drives. It provides 20 Nm stall torque, enabling strong acceleration and deceleration on heavy‑duty CNC axes and automation cells, while maintaining smooth, precise positioning.
This Fanuc AC servo motor features 3‑phase AC brushless technology with a tapered shaft (ST) and straight‑keyed shaft (SLK) configuration, making it suitable for direct coupling and gearbox connections. The 24 V brake (24 V BRK) ensures safe holding torque when power is removed, and the b128iA pulse‑coder supplies high‑resolution feedback for accurate speed and position control when paired with compatible Fanuc servo amplifiers.
Physically, the A06B‑0085‑B403 is built for robust industrial use, with sealed construction and vibration‑resistant design. The motor is designed to integrate seamlessly into CNC machining centers, turning machines, and multi‑axis automation setups, and is typically supplied with 1‑year warranty for new units. With fast delivery and OEM‑grade reliability, this Fanuc BiS22/2000 servo motor is ideal for upgrades, rebuilds, and high‑performance motion‑control projects.
