Abstract

Die Erfindung betrifft einen Elektromotor (3) mit einem Stator (4) und einem Rotor (5), einem mit dem Rotor (5) verbundenen Gebläserad (7) und einem zugeordneten, feststehenden Diffusor (9), wobei das Gebläserad (7) zusammen mit dem Diffusor (9) von einer mittig offenen Kappe (1) überfangen ist. Um einen Elektromotor der in Rede stehenden Art derart verbessert auszugestalten, dass der Hauptanteil des im Gebläse entstehenden Geräuschs am Entstehungsort möglichst breitbandig absorbiert wird, wird vorgeschlagen, dass innerhalb der Kappe (1), zugeordnet dem Diffusor (9) ein Schalldämpfungselement (17) angeordnet ist.
