Abstract	Os principais equipamentos encontrados para realizacao de movimentos mecânicos sao os motores eletricos, sendo que a maior parte destes e constituida pelos motores de inducao trifasicos. E inegavel a crescente preocupacao com a questao da eficiencia energetica, sendo estes equipamentos os maiores consumidores de energia eletrica, principalmente, nas industrias. Sendo assim, este trabalho apresenta uma plataforma experimental implementada para a obtencao do rendimento dos motores de inducao trifasicos a partir da determinacao dos parâmetros do circuito equivalente, de ensaios termicos e ensaios especificos para obter as perdas da respectiva maquina, com base em procedimentos presentes na norma tecnica NBR17094-3:2018 da Associacao Brasileira de Normas Tecnicas. Neste contexto, o rendimento foi obtido para diversos carregamentos para um motor de 3 cv a partir da variacao de carga em seu eixo, utilizando, para isso, uma maquina de corrente continua. Tal plataforma permite verificar o desempenho de motores antigos, motores que passaram por processo de rebobinagem ou motores construidos sob encomenda. Palavras-chaves : NBR17094-3:2018.

Experimental platform for efficiency analysis of the three-phase induction motors through specific tests recommended in the technical standard NBR17094-3:2018 Abstract The main equipment used to perform mechanical movements are electric motors, since its majority are composed by three-phase induction motors. There is an undeniable growing concern about the energy saving, being this equipment the major consumers of electricity, especially in industries. Thus, this work presents an experimental platform, implemented to get the performance of the three-phase induction motors from the determination of equivalent circuit tests, thermal tests and specific tests to obtain the losses of the testing machine based on procedures in technical standard NBR17094-3: 2018 of the Brazilian Association of Technical Standards. In this context, the yield was obtained for several loads for a 3 cv engine from the load variation on its axle using a direct current machine. Such platform makes it possible to check the performance of older engines, engines undergoing the rewinding process or custom manufacturing engines. Keywords : NBR17094-3:2018. Three phase induction motor. Efficiency. Parameters.
