COMPARISON OF BRAZILIAN STANDARDS FOR THE QUALIFICATION OF THREE-PHASE INDUCTION MOTORS AGAINST A GLOBAL SCENARIO

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 energy consumption of the Brazilian industrial sector. Countries like Japan, members of the European Union, the United States, Australia, India, and Brazil have specific standards to qualify their equipment.  These, among other countries, have regulatory or even mandatory regime mechanisms that classify the efficiency of three-phase induction motors, using specific standards and regulations. In this way, this article aims to compare the application of national standard methods with international methods, making it possible to qualify the national standard against a global scenario. This articles compares the test standards IEEE 112 Method B, IEC 60034-2-1, JEC 37 and ABNT NBR 17094-3, these standards have different methodologies, so that when the same engine is tested by them their efficiency can present different results, generating large discourses among international committees on which standard is the most appropriate for this type of trial.
