Abstract

L'invenzione concerne un apparecchio di comando elettromagnetico con un nucleo magnetico in più parti, il quale è azionabile in direzione di chiusura per mezzo di una bobina, in particolare un relé di comando con un nucleo magnetico di un indotto incernierato.Per ridurre la potenza elettrica dispersa e aumentare la sicurezza di funzionamento dell'apparecchio dì comando secondo l'invenzione viene proposto che il nucleo magnetico (1, 2) è collegato con un sensore (3) del flusso magnetico per rilevare una grandezza proporzionale al flusso magnetico, e che il sensore (3) del flusso magnetico è collegato con un dispositivo regolatore elettronico (5), in modo che la potenza elettrica, alimentata alla bobina (4), sia regolabile attraverso la grandezza determinata proporzionale al flusso magnetico.
