Previous issue date: 2010-02-19 / This work presents a diagnosis faults system (rotor, stator, and contamination) of
three-phase induction motor through equivalent circuit parameters and using techniques
patterns recognition. The technology fault diagnostics in engines are evolving and becoming
increasingly important in the field of electrical machinery. The neural networks
have the ability to classify non-linear relationships between signals through the patterns
identification of signals related. It is carried out induction motor?s simulations through
the program Matlab R
& Simulink R
, and produced some faults from modifications in
the equivalent circuit parameters. A system is implemented with multiples classifying
neural network two neural networks to receive these results and, after well-trained, to
accomplish the identification of fault?s pattern / Este trabalho apresenta um sistema de diagn?stico de falhas (rotor, estator e contamina??o)
do motor de indu??o trif?sico atrav?s dos par?metros do circuito equivalente e
utilizando t?cnicas de reconhecimento de padr?es. A tecnologia de detec??o de falhas em
motores est? evoluindo e tornando cada vez mais importante na ?rea de m?quinas el?tricas.
As redes neurais possuem a habilidade de classificar rela??es n?o lineares entre sinais
atrav?s da identifica??o de padr?es dos sinais relacionados. S?o realizados simula??es do
motor de indu??o atrav?s do programa Matlab R
& Simulink R
e produzido alguns tipos
de falhas no conjunto a partir de modifica??es nos par?metros do circuito equivalente. ?
implementado um sistema com m?ltiplos classificadores neurais para receber estes resultados
e, ap?s o treinamento, realizar a identifica??o dos padr?es de falhas
