Abstract

Procedimento per il controllo di un motore brushless (1) dotato di n (n > 2) avvolgimenti comprendente le fasi di:- rilevare le forze elettromotrici (E1, E2, E3) sviluppate nel funzionamento negli avvolgimenti (W1, W2, W3) del motore (1),- confrontare dette forze elettromotrici (E1, E2, E3) con un valore di riferimento (V-BAT) predeterminato per generare un primo segnale di sincronizzazione (TOGGLE),- generare, a partire da detto primo segnale di sincronizzazione (TOGGLE), un segnale di controllo (SW) indicativo della posizione angolare del rotore di detto motore (1),- confrontare detto segnale di controllo (SW) con un primo ed un secondo segnale di riferimento (REF-ON, REF-OFF) per generare segnali di attuazione (C1, C2, C3) atti a controllare il passaggio di corrente in detti avvolgimenti,- variare detti segnali di riferimento (REF-ON, REF-OFF) in vista di modificare gli istanti di inizio e fine della conduzione di corrente nelle fasi (W1, W2, W3) del motore (1).(Figura 2).
