Abstract
(DE)
Die Erfindung betrifft einen Kompressor (1) für einen Ansaugtrakt (2) einer Verbrennungskraftmaschine eines Kraftfahrzeugs, mit einem Elektromotor (4), welcher einen Stator (5) und einen von dem Stator (5) antreibbaren und dadurch um eine Drehachse (7) relativ zu dem Stator (5) drehbaren Rotor (6) aufweist, und mit einem Verdichterrad (8), welches zum Verdichten von den Ansaugtrakt (2) durchströmender und wenigstens einem Brennraum der Verbrennungskraftmaschine zuzuführender Luft von dem Rotor (6) antreibbar ist, wobei der Elektromotor (4) als bürstenloser Außenläufer (10) ausgebildet ist, sodass zumindest ein Längenbereich des Stators (5) in zumindest einem Längenbereich des Rotors (6) angeordnet ist.
(EN)
The invention relates to a compressor (1) for an intake section (2) of an internal combustion engine of a motor vehicle, with an electric motor (4) which has a stator (5) and a rotor (6) which can be driven by the stator (5) and can be rotated as a result about a rotational axis (7) relative to the stator (5), and with a compressor impeller (8) which can be driven by the rotor (6) in order to compress air which flows through the intake section (2) and is to be fed to at least one combustion chamber of the internal combustion engine, wherein the electric motor (4) is configured as a brushless external-rotor motor (10), with the result that at least one length region of the stator (5) is arranged in at least one length region of the rotor (6).
(FR)
L’invention concerne un compresseur (1) pour un collecteur d’admission (2) d’un moteur à combustion interne d’un véhicule à moteur, comportant un moteur électrique (4) qui présente un stator (5) et un rotor (6) pouvant être entraîné par le stator (5) et pouvant ainsi tourner autour d’un axe de rotation (7) par rapport au stator (5), et une roue de compresseur (8) pouvant être entraînée par le rotor (6) pour comprimer l’air passant à travers le collecteur d’admission et alimentant au moins une chambre de combustion du moteur à combustion interne, le moteur électrique (4) étant conçu sous forme de rotor extérieur sans balais (10), de telle sorte qu’au moins une zone longitudinale du stator (5) est disposée dans au moins une zone longitudinale du rotor (6).
