Abstract

Motore brushless in corrente continua in cui le fasi (W1, W2, W3) vengono energizzate e sequenzialmente in modo tale per cui esiste un intervallo di tempo in cui le due fasi che vengono commutate sono entrambe energizzate. Inoltre il motore è configurato in modo tale che le forze elettromotrici (E1, E2, E3) indotte nelle fasi (W1, W2, W3) si sovrappongono, cioè esistono intervalli in cui le forze elettromotrici in due fasi adiacenti sono entrambe al loro valore massimo. Grazie a tali caratteristiche il motore secondo l'invenzione presenta un'oscillazione di coppia (TQ) e di corrente (IL) estremamente ridotta e conseguentemente genera pochissimo rumore acustico od elettrico.(Figura 2).
