Abstract

Un motore elettrico sincrono è formato da un pacco lamellare statorico (2) provvisto di almeno un avvolgimento elettrico (6, 6') e da un rotore (3) in materiale ad elevata retentività magnetica; i lamierini (4) del pacco (2) sono disposti parallelamente all'asse del rotore (Z) per limitare l'ingombro trasversale del motore (1). Il pacco lamellare (2) ha sostanzialmente forma di U con tronchi rettilinei (5, 5') sui quali sono previsti avvolgimenti (6, 6') con assi delle spire sostanzialmente paralleli all'asse (Z) del rotore (3); i lamierini (4) hanno, in corrispondenza dei tronchi (5, 5'), altezze differenziate lungo una direzione trasversale (X) rispetto all'asse (Z) del rotore (3). Il pacco lamellare (2) con i suoi avvolgimenti è annegato in una matrice di resina (12) isolante, a sua volta ermeticamente racchiuso entro un involucro (11) sostanzialmente rigido di materiale dielettrico formando una capsula modulare sigillata. Tale capsula può essere accoppiata ad unità rotoriche di diversa tipologia per formare pompe immergibili.
