Abstract

<B>CONTROLE DE MOTOR DE RESISTêNCIA ALTERNADA SEM SENSOR<D>. Um método para controlar um motor e um circuito para implementação deste método são fornecidos. O método inclui as etapas de fornecimento de corrente para uma primeira bobina de fase de um motor e de medição do tempo para a elevação da corrente entre dois níveis predeterminados. O tempo de elevação de corrente medido pode ser comparado ao tempo de elevação de corrente desejável para determinar se os intervalos de condução nas fases do motor estão em fase com a posição do rotor ou, estão atrasando ou avançado a posição do rotor, pois o tempo de elevação de corrente é proporcional à indutância da fase e consequentemente à posição do rotor. O método finalmente inclui a etapa de fornecimento de corrente para uma das, primeira ou segunda, bobinas de fase, em resposta ao tempo de elevação de corrente medido, a fim de colocar intervalos de condução subsequentes em fase com a posição do rotor.
