FANUC A90L-0001-0510 is a 24VDC internal cooling fan for selected FANUC Alpha-i power supply, servo and spindle amplifier modules. It circulates air inside the drive housing to cool electronic components and reduce thermal faults.
The fan measures 40 × 40 × 20mm and uses a three-wire lead with a female connector for power and monitoring. A common manufacturer marking is NMB-MAT 1608KL-05W-B39; original units may carry another approved code, so check the FANUC number and connector.

Alpha-i Drive Applications
FANUC documentation lists A90L-0001-0510 for Alpha-i spindle modules including αiSP 2.2, 5.5, 11 and 15 classes and applicable HV versions. It is also used in selected Alpha-i power supply and servo amplifier modules. Compatibility depends on the complete A06B drive model.
Fan Motor and Fan Unit Numbers
A90L-0001-0510 identifies the fan motor. A06B-6110-C605 and A06B-6110-C606 are fan-unit references that include mounting parts for particular modules. Confirm whether the quotation covers the fan motor alone or a complete fan unit.
Replacement Checks
Compare the A90L number, manufacturer label, voltage, current, frame size, thickness, three-wire pin order, connector, lead length and airflow direction. Do not substitute A90L-0001-0511 or radiator fans A90L-0001-0507/0508/0509 because their applications differ.
Testing and Installation Notes
REACO CNC checks the label, connector, lead wires, bearing noise, rotation, airflow and monitoring output where applicable. Disconnect power and allow the DC bus to discharge before replacement. Install the fan in the documented airflow direction and keep its cable clear of the blades.
