Sažetak
As energy efficiency is becoming more and more important, it was no surprise that IEC introduced new standards with mandatory efficiency classes for the biggest electric power consumers, electric motors. More precisely, induction motors which are estimated to use more than 60% of worldwide electric energy. IEC 60034-30-1:2014 defines efficiency classes IE1, IE2, IE3 and IE4 (where IE4 is highest rating i.e. biggest energy savings) for induction motors rated for sinusoidal voltage. Measurement methods required equipment accuracy and data analysis are described in 60034-2-1. Edition 2.0 of this standard came into force in June 2014 and replaced edition 1.0. from year 2007. Before this standard, the valid standard was IEC 60034-2:1996. The main issues are: efficiency classes became mandatory from year 2009 and not just voluntary as before, an agenda to unify class standards all over the world under these new IEC standards has been put forth and measurement methods are standardized worldwide. In this paper, one induction motor will be tested according to the newest standard and analyzed to check how different methods of loss calculation affect efficiency. Loss calculation will be determined acc. to IEC 60034–2, IEC 60034-2-1 (direct and indirect method).
