Abstract

La présente invention concerne une motopompe (1) à rotor noyé, comprenant : un carter (10) incluant un corps (11) et une enveloppe moteur (12), un moteur (20) électrique synchrone qui est agencé dans l'enveloppe moteur (12) et qui inclut un stator (30) et un rotor (40) à aimants (42), un arbre (50) qui s'étend suivant un axe central (X1), et une roue (60) qui présente un profil hydraulique adapté au déplacement d'un fluide (F) dans le corps (11) ; le rotor (40), l'arbre (50) et la roue (60) formant un ensemble rotatif (ER1) mobile en rotation autour de l'axe central (X1) ; le stator (30) incluant un noyau magnétique, un bobinage (32) et une encapsulation (34) dans laquelle le bobinage (32) et le noyau magnétique sont noyés ; un entrefer magnétique (22) étant défini radialement entre le bobinage (32) et les aimants (42) ; l'encapsulation (34) comportant une partie annulaire (35) qui entoure le rotor (40) et un fond (36) qui traverse l'axe central (X1) ; le fond (36) de l'encapsulation (34) présente une forme de cloche bombée.
