Abstract

Die Erfindung betrifft ein an dem Rotor eines Elektromotors (1) angebrachtes Gebläserad (3), wobei das Gebläserad (3) eine Gebläseradachse (x) und, von einem mitdrehenden Deckenteil (8) überdeckte Gebläseradschaufeln (7) aufweist, wobei weiter die Gebläseradschaufeln (7) eine Erstreckung in Achsrichtung aufweisen. Um ein Gebläserad der in Rede stehenden Art insbesondere strömungstechnisch weiter zu verbessern, wird vorgeschlagen, dass das Deckenteil (8) die Gebläseradschaufeln (7) radial außen in Richtung der Achse (x) zur Hälfte oder mehr der axialen Erstreckung der Gebläseradschaufeln (7) überdeckt.

The invention relates to an impeller (3) mounted on the rotor of an electric motor (1), the impeller (3) having an impeller axis (x) and impeller vanes (7) covered by a co-rotating cover part (8), the impeller vanes (7) further 7) have an extension in the axial direction. In order to further improve a fan wheel of the type in question in particular fluidically, it is proposed that the ceiling part (8) covers the fan wheel blades (7) radially outward in the direction of the axis (x) to half or more of the axial extent of the fan wheel blades (7) ,
