Marathon 1VE145TTFR5655AA 2HP 3-Phase AC Motor 208-230/460V 1730 RPM TEFC 145TC

Marathon 1VE145TTFR5655AA 2HP 3-Phase AC Motor 208-230/460V 1730 RPM TEFC 145TC

The Marathon Electric 1VE145TTFR5655AA is a 2HP general purpose three-phase AC induction motor in a TEFC (Totally Enclosed Fan Cooled) enclosure. Built on a NEMA 145TC frame with permanently lubricated ball bearings, it is rated for continuous duty across a wide voltage range — 208-230V or 460V — making it adaptable to both lower and higher voltage three-phase services. Manufactured by Marathon Electric of Wausau, Wisconsin.

Applications

NEMA 145TC frame general purpose three-phase induction motors like this Marathon Electric model are workhorses of industrial and commercial machinery. They are used to drive pumps, compressors, conveyors, fans, blowers, machine tools, and a wide range of other mechanical loads wherever a reliable, continuous-duty 3-phase AC source is available. The TEFC enclosure makes them suitable for dusty or damp environments where an open drip-proof motor would not be appropriate. The dual voltage rating (208-230/460V) means this motor can be reconnected to match either a lower or higher voltage three-phase supply, giving it broad compatibility across different plant electrical systems. Marathon Electric has been a major OEM supplier of NEMA-frame motors for decades, and the 145TC frame is one of the most common standard footprints in North American industrial equipment, meaning this motor can often serve as a drop-in replacement in many applications.
