OAO motors must be mounted within the airstream — the moving air is what cools the motor.
Nameplate check: most distributors list this motor at 1140 RPM, but one lists 1075 RPM — confirm the speed on your nameplate before quoting. Distributor listings also disagree on insulation class (one says Class H, one says Class B), so check that field on the nameplate too.
Confirming the right replacement
Before we quote, compare these fields on your failed motor's nameplate. If any of them differ, send us a photo of the nameplate and we'll match it exactly rather than guessing:
- Full model number — including any suffix letters
- HP, RPM, and voltage
- Frame size (e.g. 284T) and enclosure (TEFC, ODP, etc.)
- Full-load amps
