(EN) PUMP HAVING AN ELECTRIC MOTOR
(FR) POMPE DOTÉE D'UN MOTEUR ÉLECTRIQUE
Abstract
(DE)
Pumpe (5) mit Elektromotor (4), insbesondere für ein Kraftfahrzeug, zum Fördern eines Fluides, umfassend ein Laufrad (18) mit Förderelementen (19), von dem um eine Rotationsachse (27) eine Rotationsbewegung ausführbar ist, einen an dem Laufrad (18) vorhandenen Arbeitsraum, einen Elektromotor mit einem Stator (13) und einem Rotor (16), wobei der Rotor (16) mit Permanentmagneten (17) versehen ist, vorzugsweise ein Gehäuse (8), der Rotor (16) und die Permanentmagnete (17) mittels Sintern hergestellt sind, wobei die Permanentmagnete (17) an dem Rotor (16) mit einer stoffschlüssigen Sinterverbindung mit dem Rotor (16) verbunden sind
(EN)
The invention relates to a pump (5) having an electric motor (4), more particularly for a motor vehicle, for pumping a fluid, comprising an impeller (18) that has pumping elements (19) and can carry out a rotary movement about an axis of rotation (27); a working chamber around the impeller (18); an electric motor with a stator (13) and a rotor (16), the rotor (16) being provided with permanent magnets (17); and preferably a housing (8); the rotor (16) and the permanent magnets (17) being produced by sintering, and the permanent magnets (17) on the rotor (16) being integrally bonded to the rotor (16) by sintering.
(FR)
L'invention concerne une pompe (5) dotée d'un moteur électrique (4), notamment pour véhicule automobile, permettant de refouler un fluide et comprenant un pignon (18) doté d'éléments de transport (19) et permettant d'exécuter un mouvement de rotation autour d'un axe de rotation (27), un compartiment de travail présent au niveau du pignon (18), un moteur électrique doté d'un stator (13) et d'un rotor (16), le rotor (16) étant pourvu d'aimants permanents (17), de préférence un carter (8), le rotor (16) et les aimants permanents (17) étant produits par frittage ; les aimants permanents (17) du rotor (16) étant reliés au rotor (16) par assemblage par frittage avec liaison de matière.
