Abstract

"SISTEMA DE ACIONAMENTO PARA UM MOTOR ELéTRICO MULTIFáSICO SEM ESCOVA, E, MéTODO PARA CONTROLAR UM MOTOR ELéTRICO MULTIFáSICO SEM ESCOVA". Um sistema de acionamento para um motor trifásico sem escova usa um algoritmo para sensoreamento de posição que mede a indutância nas fases do motor e determina a posição a partir das indutâncias medidas. De modo a reduzir ruído acústico, as indutâncias são medidas durante períodos de teste T~ sd~, que são estados condutores adicionados ao padrão PWM em cada período de PWM. Os períodos de teste têm voltagem líquida de zero e, portanto, não afetam a saída do motor, mas são suficientemente longos para permitir medição de indutância, bem como, o uso de um único sensor de corrente para sensoreamento de corrente.
