Abstract

Attuatore elettromagnetico a nucleo rotante, del tipo comportante, in una carcassa, un giogo magnetico, almeno una coppia di bobine fisse sovrapposte ed un equipaggio con nucleo magnetico mobile alla rotazione, giogo, bobine e nucleo avendo un asse comune coincidente con quello dell'attuatore stesso. In questo attuatore: il giogo comporta una singola espansione magnetica centrale, comune ad entrambe le bobine e magneticamente cooperante con la parte centrale del nucleo e due insiemi di espansione polari di estremità, reciprocamente affacciate secondo detto asse, uno per ciascuna bobina; il nucleo comporta a sua volta due insiemi di espansioni polari sporgenti assialmente dalla sua parte centrale e magneticamente cooperanti con detti insiemi di espansioni polari reciprocamente affacciate del giogo; le espansioni polari di un insieme sono sfalsate rispetto a quelle dell'altro nei due insiemi di espansioni di detto nucleo o - alternativamente - di detto giogo; e le due bobine sono alimentate alternativamente.
