Determinação das perdas suplementares em motores de indução trifásicos pelo método EH-STAR
Get PDFDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia Elétrica.Este trabalho se refere ao estudo e a implementação do método de ensaio eh-star para determinação das perdas suplementares em motores de indução trifásicos, proposto na norma IEC 60034-2-1. O ensaio eh-star é realizado sem a necessidade de acoplar o motor a um dinamômetro ou máquina auxiliar, ou seja, o motor trabalha em vazio. Durante o teste o motor é conectado em estrela, com um resistor, denominado Reh, ligado entre dois terminais de alimentação do motor, sendo o mesmo ligado a uma fonte monofásica. Como resultado aparecerá em seus terminais um sistema trifásico desequilibrado (assimétrico), que será decomposto em dois sistemas simétricos: seqüência positiva e seqüência negativa. São apresentados resultados de diversos motores testados na WEG. Também é apresentada uma simulação deste ensaio com o programa de cálculo utilizado pela WEG Motores. O presente trabalho propõe ainda um novo circuito para obtenção desta alimentação desequilibrada, ligando os terminais do motor à duas fases e o neutro de um gerador trifásico, dispensando a necessidade da utilização do resistor Reh. This work mentions the study and the implementation regarding the eh-star test method proposed in the IEC Standard 60034-2-1 for the determination of stray load losses in three-phase induction motors. This test is accomplished with no load, that is, the motor does not need to be connected to a dynamometer or an auxiliary machine. During the test, the motor is star connected with a resistor, referred to as Reh, installed between two motor terminals. The motor is fed by a single-phase voltage supply. This will result in an unbalanced (asymmetric) three-phase system at the motor's terminals, which can be decomposed into two symmetric systems: positive sequence and negative sequence. Results of several tests accomplished in WEG facilities, as well as simulation results obtained with the software used in WEG for motor calculation, are also presented. Additionaly, the present work proposes a new circuit for the attainment of this unbalanced voltage supply, using two phases and the neutral of a three-phase generator, avoiding the need for the Reh resistor
