Marathon Motors, Wausau, Wis., introduced a new line of totally-enclosed air-over (TEAO) cooling tower motors with bearing current protection using AEGIS shaft grounding rings. These NEMA premium severe-duty motors feature BlueChip quality 100% cast iron construction for rigidity and reduced vibration. With internal and external epoxy paint, sealed bearings, T-drains in both endshields for effective drainage, drive-end bearing isolators with shaft slingers and fully gasketed conduit boxes (with lead separators), they are IP56 rated and built to withstand the harsh environments of cooling towers.
Designed for 10:1 VT or 20:1 CT operation with a variable frequency drive, these motors have MAX GUARD Class F insulation.
They are ideal for use in cooling tower fans and blowers, pumps, compressors, condensers and evaporators, as well as a variety of severe-duty processing applications.
