Courtesy: WEG ElectricWEG Electric’s W40 three-phase induction motors are designed for compressors, blowers, oil well and fire pumps and industrial refrigeration applications. All models meet or exceed NEMA standards and international efficiency requirements. The W40 motor line features a rated output of 60 Hz at 15 to 2,250 hp as well as 2- or 4-pole models in NEMA frame sizes from 254T – L6808/09. Input voltage can be from 208 to 4,160 V available with ODP (IP23) protection for frames 256T to L5810 and WPI (IP24) protection for frame L6808/09. The ODP version of the W40 motor is useful for applications that do not need a high level of protection from the elements. 

W40 motors feature ball bearings, grease nipples, Class F insulation, and are suitable for inverter operation up to 460 V. Optional features include roller bearings (sleeve bearings above L5810), space heaters, an accessories terminal box, thermal protections, Class H insulation and are suitable for inverter operation above 575 V. To further enhance its cool running and maintenance free operation, lubrication options are available such as an automatic lubrication system and external AEGIS SGR Ring.
