FANUC A90L-0001-0581 is a 24VDC internal cooling fan motor used in selected FANUC Alpha i and Alpha i-B power supply, spindle and high-capacity servo amplifier modules. A commonly documented manufacturer model is NMB 2410VL-S5W-B59, rated at 0.11A with a 60 × 60 × 25mm frame.
FANUC identifies A90L-0001-0581 as the fan motor inside the A06B-6200-C610 fan unit. The complete fan unit also includes the mounting cover, so confirm whether the order requires the motor alone or the complete installation assembly.

A90L-0001-0581 vs. External Fans
A90L-0001-0581 is normally the internal cooling fan. It should not be confused with A90L-0001-0577 or A90L-0001-0578 radiator cooling fans, or with A90L-0001-0580 variants used in smaller amplifier frames. Match the FANUC number, fan label, dimensions, voltage, current, connector and airflow direction.
Testing and Replacement
REACO CNC checks the label, housing, blades, bearing noise, connector, current draw, rotation and airflow before shipment. Replace a fan showing an alarm, abnormal noise, slow rotation or intermittent startup. Qualified personnel should isolate power and allow the amplifier DC link to discharge before removing the fan.
