New 180 Frame Motor Design Launched
Marathon Electric recently redesigned its rolled steel 182/184 frame motor product line and is in the process of relocating production to a new factory in Monterrey, MX. The new design will incorporate a model number change to denote the new design. "...TTDR..." and "...TTFR..." models will become "...TTDW..." and "...TTFW...", depending upon enclosure ('D' means ODP and 'F' means TEFC). In all possible cases, we intend to maintain all other letters and numbers in the model number. Catalog numbers associated with the stock models will change as well. In order to maintain identity with the older design model, the number '1' will be added to the numeric portion of the number, e.g. "E904" (182TTDR4027) will become "E1904" (182TTDW4027). Look for information on the continuation of the 180 frame redesign (cast iron and aluminum frame) in future "What's New" releases.
210 Frame Relocation
Marathon Electric is in the process of relocating production of 213/215 frame motors to our new state-of-the-art manufacturing facility in Monterrey, MX. Phase 1 (underway) involves all rolled steel frame motors, in ODP and TEFC. Subsequent phases include cast iron and aluminum frame models. There are no design changes to the steel frame models so they will retain their current model and catalog numbers. Design enhancements are planned for cast iron and aluminum frame models, which will be announced at a later time.
Product Release - MAX+ Vector Duty Motors
Max+ is the newest addition to Marathon Electric's family of Max motors. The Max+ incorporates a low rotor inertia for fast starts, stops, and reversals. Coupled with an encoder makes this useful in applications traditionally served only by servo systems.
Belting Data Analysis for Roller Bearing Designs
In our ongoing quest to provide our customers the highest possible value in electric motors, this announcement reinforces previous communications regarding Marathon's belting data analysis service. At the time of motor quotation and/or order entry, customers are requested to provide belting data to evaluate and optimize bearing life (measured in terms of "B-10" hours).
Shaft Grounding Ring
Tired of premature bearing failures? It gives us great pleasure to introduce the Shaft Ground Ring or SGR, the latest innovative product addition to our extensive line of field installable kits.
