  W22  Three-Phase Electric Motor Motors | Automation | Energy | Transmission & Distribution | Coatings NEM A Technical Catalog  www.weg.netW22 Electric Motor2 W22 Line  The increasing demand or electrical energy to sustain globaldevelopment requires consistent heavy investments in powersupply generation. However, in addition to complex mediumand long term planning, these investments rely on naturalresources, which are becoming depleted due to constantpressures upon the environment. The best strategy,thereore, to maintain energy supply in the short term is toavoid wastage and increase energy eciency. Electricmotors play a major role in this strategy; since around 40% o global energy demand is estimated to be related to electricmotor applications. Consequently, any initiatives to increaseenergy eciency, by using high eciency electric motors andrequency inverters, are to be welcomed, as they can make areal contribution to reductions in global energy demand. At the same time as eciency initiatives make an impact intraditional market sectors, the application o newtechnologies in emerging sectors is resultingin proound changes in the way that electric motors areapplied and controlled. By integrating these changestogether with the demands or increased energy eciency,WEG has taken up the challenge and produced a new designo high eciency motor; one that exceeds the perormanceo WEG’s existing W21 motor line, which is recognisedworldwide or its quality, reliability and eciency.Using the latest generation o computerised tools, such asstructural analysis sotware (nite element analysis) andcomputer fuid dynamics, as well as electrical designoptimisation sotware, an innovative – next generation -product has been developed: the W22 motor.Several key objectives have been achieved in the design o the W22 motor: g Reduction o noise and vibration levels g Increased energy eciency and reduced thermal ootprint g Easy maintenance g Compatibility with present & uture generations o requency inverters g Flexible and modular design  www.weg.netW22 Electric Motor3 Frame 143T to 215T Frame 254T to 326T Frame 364/5T to 444/5T Frame 445/7T to 588/9T  Reducing carbon footprint and cutting costs with the W22 W22 range o three-phase induction motors, designed to oer not only signicantly lower energy consumption, but lower noiseand vibration, higher reliability, easier maintenance and lower cost o ownership.Consisting o three products, each designed to exceed the requirements o the NEMA MG 1-2009, the W22 Super PremiumEciency, NEMA Premium Eciency and High Eciency can reduce energy losses by between 10% and 50% compared withother typical motors. It’s an extremely eective way to reduce your carbon ootprint, as well as your energy costs.W22 motors ully comply with the energy eciency requirements o the EISA 2007 (Energy Independence and Security Act2007) rom USA and EcoAction rom Canada.
