However, in addition to complex medium and long term planning, these investments rely on natural resources, which are becoming depleted due to constant pressures upon the environment.

2 The best strategy, therefore, to maintain energy supply in the short term is to avoid wastage and increase energy efficiency. Electric motors play a major role in this strategy; since around 40% of global energy demand is estimated to be related to Electric Motor applications. Consequently, any initiatives to increase energy efficiency, by using high efficiency Electric motors and frequency inverters, are to be welcomed, as they can make a real contribution to reductions in global energy the same time as efficiency initiatives make an impact in traditional market sectors, the application of new technologies in emerging sectors is resultingin profound changes in the way that Electric motors are applied and controlled.

3 By integrating these changes together with the demands for increased energy efficiency, WEG has taken up the challenge and produced a new design of high efficiency Motor ; one that exceeds the performance of WEG s existing W21 Motor line, which is recognised worldwide for its quality, reliability and the latest generation of computerised tools, such as structural analysis software (finite element analysis) and computer fluid dynamics, as well as electrical design optimisation software, an innovative next generation - product has been developed: the W22 key objectives have been achieved in the design of the W22 Motor :g Reduction of noise and vibration levelsg Increased energy efficiency and reduced thermal footprintg Easy maintenanceg Compatibility with present & future generations of frequency invertersg Flexible and modular Electric Motor3 Frame 63 to 112 Frame 132 to 200 Frame 225 to call it WEGnologySustainability and Carbon Emission reduction through Premium Efficiency MotorsThe Premium Efficiency (IE3) level established in IEC 60034-30.

4 2008 is considered the highest efficiency class which a squirrel cage induction Motor can achieve whilst remaining economically is also the optimum solution to increase the efficiency of an existing application through direct , why have Premium Efficiency motors not become the Industry standard?It may be argued that premium efficiency motors are also premium in price when comparing against standard efficiency (IE1) and high efficiency (IE2) this is not strictly untrue, it should be appreciated when considering their lifetime that the cost of acquisition typically represents only 1% of the total cost of ownership of an Electric Motor . In contrast, the associated energy savings provided by premium efficiency motors far outweigh this additional investment in purchase reduction in CO2 emissions is one of the direct consequences, and therefore benefits, of increasing efficiency in example, according to the guidelines set out by the International Energy Agency (IEA) of 504kg of CO2 per 1,000kWh, it is possible to reduce CO2 emissions by approximately 1,000kg per year with one 3kw premium efficiency Motor and by 25,000kg per year with a 250kw premium efficiency Motor , when compared against equivalent standard efficiency (IE1)

5 To our website at to check the potential reduction in CO2 emissions and the return on investment of W22 Premium Efficiency W22 line from WEG is the first complete range of IE3 motors available to Electric Motor4 Minimum Energy Performance Standards Europe Increasingly, the World seeks a path of sustainability and new ways to reduce energy significant percentage of the electrical energy utilized in facilities around the World is consumed by Electric motors. Consequently, Governments around the World are implementing Energy Efficiency Programs in order to enforce the use of high efficiency until 2009, Europe did not have any specific regulations relating to the energy efficiency levels of Electric motors.

6 There existed only a voluntary agreement between Manufacturers from 1998 that determined the well known efficiency bands EFF1, EFF2 and , in July of 2009 the European Community introduced the regulation 640/2009 (implementing Directive 2005/32/EC) relating to the scope of supply, implementation dates and efficiency levels of Electric motors sold in the European market. This directive bases the efficiency levels on the values stipulated in IEC Scope of the European Ecodesign Directive covers single speed, Three-Phase 50 Hz or 50/60 Hz, squirrel cage induction motors that:g have 2 to 6 polesg have a rated voltage UN up to 1,000 Vg have a rated output PN between kW and 375 kWg are rated on the basis of continuous duty operationEffective datesg from 16 June 2011, motors shall not be less efficient than the IE2 efficiency level (defined in Table 1).

7 G from 1 January 2015 motors with a rated output of kW shall not be less efficient than the IE3 efficiency level (defined in Table 1) or meet the IE2 efficiency level and be equipped with a variable speed drive;g from 1 January 2017 all motors with a rated output of kW shall not be less efficient than the IE3 efficiency level or meet the IE2 efficiency level and be equipped with a variable speed Electric Motor5 OutputIE1 - Standard EfficiencyIE2 - High EfficiencyIE3 - Premium up to can support the movement towards these high efficiency levels by offering a comprehensive range of products that exceed the IE2 and IE3 criteria detailed above.
