Abstract

controle de um motor de ímã permanente sem escovas. trata-se de um método de controle de um motor de ímã permanente sem escova, o método compreendendo retificar uma tensão alternada para fornecer uma tensão retificada com uma ondulação de pelo menos 50% e excitar um enrolamento do motor com a tensão retificada. o enrolamento é excitado antes das passagens por zero da força contra-eletromotriz por um período de avanço e é excitado por um período de condução durante cada semiciclo elétrico do motor. o período de avanço e/ou período de condução são então ajustados em respotas às alterações na velocidade do motor e/ou no valor rms da tensão alternada de modo a manter a potência média constante. além disso, é revelado um sistema de controle que implementa o método e um sistema de motor que incorpora o sistema de controle.
