Title (EN) PERMANENT MAGNET PUMP WITH SPACED APART DIFFUSERS
(FR) POMPE À AIMANTS PERMANENTS DOTÉE DE DIFFUSEURS ESPACÉS
Abstract:
(EN) A combined pump and motor (11) has a stator (17) mounted for non-rotation in a housing (13). The stator has windings (25) that create an electromagnetic field in a stator cavity (24) when powered. An upper and a lower diffuser (31a, 31b) are mounted for non-rotation in the stator cavity. Annular clearances (39) exist between the upper diffuser and the inner diameter (23) of the stator and between the lower diffuser and the inner diameter of the stator. An impeller (49) between the lower diffuser and the upper diffuser has an array of magnets (53) circumferentially mounted around the impeller that impart rotation to the impeller in response to the electromagnetic field in the stator cavity. The array of magnets has at least one end portion extending into one of the upper and lower diffuser annular clearances.
(FR) L'invention porte sur une pompe et un moteur combinés (11) ayant un stator (17) monté de manière non-rotative dans un boîtier (13). Le stator comporte des enroulements (25) qui créent un champ électromagnétique dans une cavité de stator (24) lorsqu'ils sont alimentés. Un diffuseur supérieur et un diffuseur inférieur (31a, 31b) sont montés de manière non-rotative dans la cavité de stator. Des jeux annulaires (39) existent entre le diffuseur supérieur et le diamètre intérieur (23) du stator et entre le diffuseur inférieur et le diamètre intérieur du stator. Une turbine (49) entre le diffuseur inférieur et le diffuseur supérieur comporte un réseau d'aimants (53) montés de manière circonférentielle autour de la turbine qui confèrent une rotation à la roue en réponse au champ électromagnétique dans la cavité de stator. Le réseau d'aimants comporte au moins une partie d'extrémité s'étendant dans l'un des jeux annulaires supérieur et inférieur du diffuseur.
