Comparison of Three-Phase Induction Motors Testing Methods using ABNT 17094-3:2018 and IEC 60034-2-1:2014

Abstract

Electric motors are considered the most important equipment among those that consume final electric energy in Brazil. It is estimated that the induction motors and the systems driven by them are responsible for approximately 70% of the
Brazilian industrial sector's energy consumption. Therefore, obtain its losses is a relevant challenge for energy efficiency. Any initiative developed to increase these devices' performance brings environmental benefits, energy benefits, and cost reduction for the industrial, commercial, and other sectors. Nowadays, several standards can be used to determine the performance characteristics of induction motors. However, their application results in variations in the performance calculations. Thus, this paper evaluated two tests on three-phase induction motors comparing the different methods applied between the standards ABNT 17094-3:2018 and IEC 60034-2-1:2014. These standards present different normalized equations. Thus, this paper seeks to obtain engine performance variation when testing it using different standards, comparing and discussing the results. The results obtained confirm that the methods have different results and the parameters can be compared.
