This paper tries to show the different results between the standards for efficiency evaluation and the necessity of harmonization worldwide. Then, it is going to be explained the different standards for measurement of efficiency, and the main differences between the standards (IEEE 112, IEC 60034-2 and JEC-37). To complete this study, it is going to be described the steps in order to estimate efficiency on the jobsite and expressed the different efficiency labels motors.}, publisher = {European Association for the Development of Renewable Energies, Environment and Power Quality (EA4EPQ)}, publisher = {Renewable Energy and Power Quality Journal (RE&PQJ), 2008, 1(6), 530-534}, publisher = {International Conference on Renewable Energies and Power Quality (ICREPQ’08), Santander}, title = {How the efficiency of induction motor is measured?}, author = {Corino Diez, Sofía and Romero Arozamena, Elena and Mantilla Peñalba, Luis Fernando}, }
