Product Introduction
The FANUC A06B-6265-B400 (commonly referenced as the aiS 22/4000) is a precision-engineered AC servo motor designed for high-performance feed-axis and positioning applications in modern CNC machine tools, automation cells, and robotic systems.
Featuring a rated stall torque of 22 Nm and a maximum operating speed of 4000 RPM, this motor delivers exceptional dynamic response, rapid acceleration, and tight path accuracy. Equipped with a straight slick shaft (ST/SLK), an integrated 24V holding brake (BRK), and high-resolution feedback capabilities (aiA incremental/absolute encoder integration), it provides dependable, precise operation in demanding metal-cutting and manufacturing environments.

Compliance & Standards Alignment
- Manufactured in accordance with strict international industrial standards (CE, UL recognized insulation classes, and cUL requirements for machine tool integration).
- Built with oil-resistant shaft seals and rugged heavy-duty connectors designed to withstand harsh shop-floor conditions involving cutting fluids and metal chips.
Technical Note: When routing motor power and encoder cables, ensure proper shielding termination and separation from high-voltage lines to prevent electrical noise interference on the feedback loop.
Storage & Asset Preservation Guidelines
- Store the motor in a clean, dry indoor environment, ideally inside its original shipping container or protected under heavy-duty anti-static and moisture-barrier film.
- Keep the machined mounting flange and shaft lightly coated with a corrosion inhibitor if stored for extended periods.
- Avoid heavy mechanical impacts or storing items on top of the shaft assembly to prevent bearing brinelling or rotor imbalance.
Physical Installation Prerequisites
- Ensure that all machine tool power sources, servo amplifiers, and incoming utility feeds are completely de-energized and locked out (LOTO) prior to mechanical coupling or electrical disconnection.
- Verify that the mechanical mating surface and coupling/pulley alignment are precise to prevent excessive radial or axial load stress on the motor bearings.
- Confirm that power and encoder plug connectors are completely free of residual oil, coolant, or debris before tightening to their specified torque ratings.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this servo motor?
A: Industrial AC motors and electric servo actuators generally classify under HS code 8501.52 (AC motors, multi-phase, of an output exceeding 750 W) or 8501.53. Confirm final classification details with your customs broker.
Q: Is a core return required when purchasing a replacement motor?
A: Many industrial surplus and exchange programs offer reduced pricing conditional on returning your old, repairable core unit (Core Exchange program). Check specific supplier terms prior to finalizing your order.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market conditions, unit condition (New Surplus, Refurbished, or Exchange), and core availability; contact our technical sales desk for a formal, time-sensitive quotation.
