Manufacturers need consumers to trust their products
The International Energy Agency (IEA) says electric motors account for 45% of electricity consumption worldwide, but if they can be made more efficient, electricity savings of 20 to 30% would be possible.
In an attempt to increase electric motor efficiency, governments have introduced Minimum Energy Performance Standards (MEPS), which set obligatory minimum energy efficiency levels for motors. IEC has established four classes of energy efficiency for motors found in IEC 60034-30-1, which are IE1 Standard efficiency, IE2 High efficiency, IE3 Premium efficiency and IE4 Super premium efficiency. It has also produced IEC 60034-2-1 for testing electric motors. Today, MEPS are most often based on these International Standards.
In today’s global supply chains, since many electric motors and their driven equipment are made and shipped worldwide, it is difficult for consumers to be sure that these International Standards have been applied. Additionally, testing and verification processes and requirements vary in different countries. So how can consumers trust products?
The best way for manufacturers to inspire consumer confidence is to apply harmonized International Standards, which ensure that wherever they are in the world, they follow the same principles when defining, measuring and publishing motor efficiencies.
A globally harmonized programme for checking and certifying motor efficiency
In order to address the trade barriers which can occur because of differing country regulations, IECEE, the IEC System of Conformity Assessment Schemes for Electrotechnical Equipment and Components, has developed the Global Motor Energy Efficiency Programme (GMEE) for motor efficiency.
It is based on the international IECEE CB Scheme, which in turn is based on International Standards. GMEE aims for one product, one test and one certificate, by promoting the harmonization of national standards with International Standards.
