FANUC A97L-0218-0929#450N-270 / #450N-290 Rotary AC Motor with Pinion – FANUC 2000iD Robot Series
When a rotary AC motor fails on a FANUC 2000iD robot, the entire production line stops. Whether it’s an automotive body-welding cell, a heavy-payload palletizing station, or a precision arc-welding application, the loss of axis drive means unplanned downtime measured in thousands of dollars per hour. The FANUC A97L-0218-0929#450N-270 and A97L-0218-0929#450N-290 are the OEM-specified rotary AC servo motors with integrated pinion gear that restore full axis functionality — and there is no generic substitute that meets FANUC’s torque ripple and encoder compatibility requirements.
Within the FANUC 2000iD heavy-payload robot family, the A97L-0218-0929#450N series occupies the critical joint-drive position requiring high continuous torque output combined with compact axial length. The #450N-270 variant covers a 270° rotation range application, while the #450N-290 covers the 290° variant — both sharing the same motor body, pinion interface, and αiF-series amplifier compatibility. These motors are globally recognized as the benchmark for reliability in FANUC’s largest industrial robot platforms, deployed across automotive OEMs, aerospace manufacturers, and heavy-industry automation integrators worldwide.

- Vibration & Shock Resistance: Designed to withstand the mechanical stress of heavy-payload joint operation in continuous production environments.
Industry & Equipment Applications
- Automotive Manufacturing: Body-in-white welding, press-tending, and heavy-part transfer on FANUC 2000iD robot cells.
- Aerospace & Defense: Large-structure assembly and drilling applications requiring high repeatability under heavy loads.
- Heavy Palletizing & Material Handling: End-of-line palletizing with payloads up to 1,700 kg using FANUC 2000iD/1700.
- Foundry & Die Casting: Extraction and handling in high-temperature, high-vibration environments.
- General Industrial Automation: Any FANUC 2000iD installation requiring axis motor replacement or preventive maintenance.
System Integration & Compatible Parts
The A97L-0218-0929#450N series integrates directly with the following FANUC components:
- FANUC αiF Series Servo Amplifier Modules (A06B-6240 series)
- FANUC R-30iB / R-30iB Plus / R-30iB Mate Plus Controllers
- FANUC 2000iD Joint Reducer (matched pinion interface)
- FANUC αi Pulse Coder Cable Assemblies (A660-2005 series)
- FANUC Power Motor Cable (A660-2004 series)
When replacing this motor, we recommend simultaneously inspecting the joint reducer grease condition and the servo amplifier’s current feedback calibration to ensure full system restoration.

Frequently Asked Questions
Q: What is the difference between A97L-0218-0929#450N-270 and A97L-0218-0929#450N-290?
A: The suffix indicates the mechanical rotation range of the motor-pinion assembly: 270° for the #450N-270 and 290° for the #450N-290. Both variants use the same motor body and are electrically identical; the difference lies in the joint axis travel limit they are designed to support.
Q: Are these new or refurbished parts?
A: We supply both new-old-stock (NOS) and professionally refurbished units depending on availability. The condition is clearly stated in your quotation. Refurbished units undergo full inspection and functional testing.
Q: Will I need to re-master the FANUC robot after replacing this motor?
A: If you replace with the identical part number and the absolute encoder battery backup was maintained during the swap, re-mastering is typically not required. However, we always recommend verifying zero-point calibration after any motor replacement as per FANUC’s maintenance manual.
Q: Can you supply the matching servo amplifier and cables?
A: Yes. We can source the complete drive system including the αiF amplifier module, power cables, and encoder cables. Please include your requirements in your inquiry.
Q: What is the lead time for this part?
A: Lead time varies by current stock. Please submit an inquiry for a real-time availability check. We typically respond within 1 business day.
