Title
(EN) LIQUID FILLED ELECTRIC MOTOR
(FR) MOTEUR ELECTRIQUE REMPLI D'UN LIQUIDE
Abstract
(EN)
A liquid filled electric motor comprising at least one gas filled pressure cushioning or absorbing non-porous flexible material member (10) located within the motor housing (3) remote from the rotor assembly (5) and spaced around the shaft (5a) of the rotor assembly and in contact with the liquid (4) in the motor housing (Fig 1). Also, a submersible pump comprising the liquid filled electric motor.
(FR)
L'invention porte sur un moteur électrique rempli d'un liquide et comprenant au moins un matériau (10) flexible, non poreux, amortissant ou absorbant la pression et rempli d'un gaz, ce matériau étant placé à l'intérieur du carter (3) du moteur, ce dernier se trouvant à distance de l'ensemble rotor (5) et étant espacé autour de l'arbre (5a) de l'ensemble rotor et étant en contact avec le liquide (4) dans le carter du moteur. L'invention porte également sur une pompe submersible comprenant le moteur électrique rempli de liquide.
