Abstract
Il dispositivo di protezione secondo l'invenzione per motori elettrici possiede una resistenza PTC a forma di piastrina come elemento di protezione 34, 80 nel circuito del motore, la quale è eseguita e, oppure disposta in modo che il suo riscaldamento, provocato dal passaggio della corrente e dalla temperatura ambiente provoca la limitazione della corrente, prima che possano essere surriscaldate e danneggiate zone locali dell'elemento di protezione.Con l'esecuzione, oppure disposizione secondo l'invenzione si è ottenuto che l'elemento di protezione 34 80 aumenta la sua intera resistenza elettrica così rapidamente che non possono essere surriscaldate e danneggiate zone superficiali locali dell'elemento di protezione.Il settore di impiego preferito è rappresentato dai motorini per dispositivi di azionamento ausiliari in autoveicoli (figura 1).
