Abstract

Die Erfindung betriffteine elektrische Maschine (1), insbesondere Klauenpolmaschine, mit einem Rotor (2) und wenigstens einem von dem Rotor (2) angetriebenen Lüfterrad (4), das über mehrere voneinem Grundkörper (8) des Lüfterrads (4) ausgehende Lüfterschaufeln (9) verfügt. Dabei ist vorgesehen, dass zwischen jeweils zwei unmittelbar benachbarten Lüfterschaufeln (9) ein Schaufelabstandswinkel vorliegt, der einem Basisabstandswinkel (α) oder einem ganzzahligen Vielfachen des Basisabstandswinkels (α) entspricht, wobei der Basisabstandswinkel (α) gleich dem kleinsten an dem Lüfterrad (4) vorliegenden Schaufelabstandswinkel und kleiner als 12° ist.
