The A06B-2085-B107 belongs to FANUC’s A06B-2085 series of AC servo motors, commonly used as feed axes on CNC machine tools and other high‑performance motion systems. It is described as “AC SERVO MDL BiS 22/2000, ST, SLK, BiA 1000”, indicating a BiS 22/2000 motor type with a straight (ST) slick (SLK) shaft and a BiA 1000 encodeur. The BiS 22/2000 designation identifies the mechanical/electromagnetic frame size and speed‑torque class, while the BiA 1000 encoder provides high‑resolution incremental feedback for accurate positioning and speed control.
According to FANUC parts distributors, this motor is designed for robust industrial duty, with sealed construction and precision bearings to withstand demanding machining environments and continuous operation. The straight slick shaft simplifies coupling to gearboxes, ball screws or belt drives, without keyways or other special features, making integration flexible in retrofits and OEM designs. The BiA 1000 encoder ensures that motion is monitored finely enough for tight contouring and repeatable positioning in CNC applications.
Suppliers describe A06B-2085-B107 as suitable for a wide range of FANUC CNC platforms and often sell it as new original or refurbished with 12‑month warranty, highlighting its role as a drop‑in replacement for failed motors in existing FANUC systems. Typical application areas include CNC machining centers, lathes, grinding machines, and other industrial equipment where high servo stiffness and reliability are required.
