Abstract

Motopompa comprendente un motore elettrico dotato di uno statore (1), un rotore (2) ed un albero rotante (3) associato a detto rotore, una camera a tenuta (5), una girante, (6) disposta entro detta camera e vincolata sulla testa libera di detto albero rotante, una prima guarnizione anulare (7) disposta in detta camera e una seconda guarnizione anulare (8) bloccata sull'albero (3), dette prima e seconda guarnizioni anulari (7, 8) essendo reciprocamente impegnate in un accoppiamento a pressione in cui la fase di avviamento del motore il rotore è atto a girare liberamente per un determinato arco iniziale senza che la coppia motrice sviluppata venga applicata a detto accoppiamento. Detto albero (3) è formato e disposto in modo da consentire una rotazione parziale iniziale del rotore rispetto a detta girante, e viene fornita alle polarità del motore un'alimentazione elettrica tale da far girare per un breve periodo iniziale il rotore in senso opposto al senso normale.
