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.
Our Quality Assurance Process

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.
