The A06B‑1408‑B103 AC spindle motor is a 3‑phase induction spindle servo motor engineered for high‑speed milling, drilling, and tapping in industrial CNC machines. It belongs to the AI 12/7000 spindle‑motor family, known for wide constant‑power range, high torque at low speed, and high power at high speed, making it ideal for hard‑metal and high‑feed‑rate machining.
This AC spindle motor uses an induction motor structure without a commutator, providing robust, low‑maintenance operation and excellent durability in continuous‑cutting environments. The motor is designed to work with Fanuc αi‑series spindle amplifiers and CNC controllers, ensuring precise spindle‑speed control, smooth acceleration, and effective overload protection. The spindle is typically mounted via a flange and includes features such as integrated encoders and coolant‑through options on some variants for enhanced thermal management and cutting‑fluid delivery.
Physically, the A06B‑1408‑B103 is a compact, high‑density built‑in spindle motor weighing 100 kg, suitable for integration into CNC machine spindles and gantry‑type processing centers. It is manufactured in Japan under strict quality controls and is typically supplied with a 1‑year warranty for new units and short‑lead‑time delivery for in‑stock items. With OEM‑grade performance and compatibility, this Fanuc AC spindle motor is the preferred choice for machine‑tool builders, rebuilders, and CNC maintenance teams seeking reliable, high‑performance spindle solutions.
