O motor síncrono de ímã permanente (PMSM) é um componente essencial em várias aplicações.
em várias aplicações, mas continua suscetível a uma série de falhas tanto no rotor quanto no estator.
Por isso, é imperativo resolver esses problemas de forma rápida e inteligente. Neste
estudo, foi adotada uma nova abordagem em que um projeto de PMSM foi conceituado no programa
programa Ansys Maxwell, seguido pela introdução deliberada de uma falha no nível magnético do rotor.
nível magnético do rotor. Especificamente, três cenários de falha distintos foram delineados com base no
número de ímãs quebrados (BM), a saber, 2, 3 e 4, localizados em áreas específicas do rotor.
Notavelmente, a densidade do fluxo magnético foi selecionada como o parâmetro focal para essa investigação.
Para detectar e diagnosticar com eficácia as falhas decorrentes de BM, uma arquitetura inovadora de rede neural convolucional
(CNN) inovadora foi desenvolvida. Aproveitando as imagens do projeto do PMSM
PMSM capturadas durante as fases operacionais em vários intervalos de tempo, a CNN demonstrou uma
notável eficácia no discernimento e na categorização de instâncias de falhas. Após a análise dos resultados derivados
resultados derivados, fica evidente que a CNN apresentou uma precisão sem igual na
detecção de falhas, alcançando uma notável taxa de sucesso de 100% quando comparada com
metodologias alternativas, como Support Vector Machines (SVM) e K-Nearest Neighbors (KNN),
que produziram taxas de precisão de 97%.
