The present invention relates to an electric centrifugal pump (1) for conveying a fluid, in particular for conveying fuel to an aircraft engine, comprising a housing (2) in which a rotor shaft (3) is rotationally mounted and an impeller (4) for conveying the fuel is arranged on said rotor shaft, wherein a motor arrangement is provided for driving the rotor shaft (3) in a rotary manner around a rotor axis (5). According to the invention, said impeller (4) comprises at least one rotor (6), and at least one stator (7) is arranged in the housing (2) in a plane-parallel manner adjacent to the rotor (6), such that said rotor (6) and the stator (7) form the motor arrangement.
L'invention concerne une pompe centrifuge électrique (1) destinée à transporter un fluide, notamment du carburant vers une turbine d'avion, comportant un boîtier (2) dans lequel un arbre de rotor (3) est logé rotatif et une roue centrifuge (4) est disposée sur l'arbre de rotor (3) pour le transport du carburant. Un système de moteur est prévu pour l'entraînement rotatif de l'arbre de rotor (3) autour d'un axe de rotor (5). Selon l'invention, la roue centrifuge (4) comporte au moins un rotor (6) et au moins un stator (7) est disposé de façon plane et parallèle à côté du rotor (6), dans le boîtier (2), de telle manière que le rotor (6) et le stator (7) forment le système de moteur.
