MPN: A90L-0001-0555/RW
Stock #: 0226-00073

The Fanuc A90L-0001-0555/RW is a spindle motor cooling fan manufactured by Minebea Co. Ltd. under OEM part number RT8934-0220W-B30F-S02. This centrifugal blower style fan is used to cool Fanuc AC spindle motors in CNC machining centers, lathes, and turning centers. Serial number 002475 is present on the nameplate. The unit features a sirocco style impeller mounted within a sheet metal housing with four corner mounting brackets, a black power lead, and a three wire pigtail termination for connection to the spindle motor terminal block. The /RW suffix designation identifies this as a specific variant within the A90L-0001-0555 family of Fanuc spindle fans, distinct from the /R, /F, and #F revisions. Fanuc part numbers in the A90L-0001 series are referenced across Fanuc maintenance documentation for alpha, alpha i, and beta series AC spindle motors. Replacement of spindle motor cooling fans is a recommended periodic maintenance item, as accumulated dust and contamination on the impeller reduces airflow and can lead to elevated spindle motor temperatures, thermal alarms, and degraded amplifier reliability. The Minebea OEM source markings remain visible on both the rating label and the integrated motor hub. Mounting bracket footprint, hub geometry, and electrical termination correspond to factory Fanuc spindle motor installations.
