Controle linear de máximo torque de um motor síncrono de ímãs permanentes interiores

Abstract: Neste artigo é apresentado o controle linear de torque de um motor síncrono de ímãs permanentes interiores funcionando nas regiões de torque constante e de potência constante. O controle de torque constante é implementado através da curva de máximo torque por Ampère do motor. A tensão de terminal do estator é mantida constante ao longo da região de enfraquecimento mediante o controle da reação de armadura. Para melhorar a resposta dinâmica do controle, o controle de máximo torque por Ampère é estendido à regiã… Show more

“…das reduções aplicadas, os motores também contam com recursos designados para aprimorar a relação energia-força. O uso de motores síncronos de ímãs permanentes gera uma eficiência 2% a 3% maior que a de motores de indução pois o rotor é formado por ímãs de alta densidade de fluxo, o que permite temperatura e sistema de ventilação menores, tornando o motor mais compacto(FIGUEIREDO, BIM, 2010).…”
