Abstract

Circuito di controllo per un sistema contenente un motore commutato elettronicamente. Un generatore di segnale tachimetrico ad impulsi genera un segnale rappresentante la velocità di rotazione del rotore di un motore ed avente un ciclo attivo. Il circuito di controllo comprende primi e secondi circuiti inibitori di tensione di motore. Il primo circuito inibitore impedisce l'applicazione della tensione di motore agli stadi di avvolgimenti del motore a seguito del segnale tachimetrico ad impulsi quando la velocità di motore è al di sotto di una prefissata velocità minima. Il secondo circuito di inibizione impedisce l'applicazione di tensione di motore agli stadi di avvolgimenti a seguito del segnale tachimetrico ad impulsi quando il ciclo attivo del segnale tachimetrico ad impulsi è al di fuori di una prescelta gamma accettabile. L'applicazione della tensione di motore agli stadi di avvolgimenti è impedita quando il motore è arrestato, come indicato dalla velocità di motore al di sotto di una prefissata velocità minima, o come indicato dal ciclo attivo del segnale tachimetrico ad impulsi al di fuori della prescelta gamma accettabile.
