Abstract

Si tratta di un gruppo di frenatura con sblocco di emergenza per motori elettrici comprendente da uno o più dischi di riscontro (20', 20) calettati e suscettibili di spostamenti assiali sull'albero motore (13), da uno o più dischi frenanti (18) frapposti ai dischi di riscontro (20', 20) calettati e movibili assialmente in una flangia di testa (16) del motore concentrica all'albero motore e da una molla (21) che sollecita almeno uno dei dischi di riscontro (20') per mantenere serrati a pacco in posizione di frenatura dell'albero motore i dischi di riscontro e frenanti (20', 20, 18) a motore fermo, detti dischi allontanandosi per la sfrenatura dell'albero motore ad opera del campo magnetico creato dal motore quando è in funzione.FIGURA 1.
