Abstract

Es wird eine elektrische Maschine, insbesondere ein Drehstromgenerator für Kraftfahrzeuge, mit einem Stator (16) und einem Rotor (20) vorgeschlagen, wobei der Rotor (20) eine axiale Stirnfläche (30 bzw. 31) hat, an der eine Ventilationsvorrichtung (33) befestigt ist, die mehrere Lüfterschaufeln (36) umfasst. Es ist dabei vorgesehen, dass sich die Ventilationsvorrichtung (33) in radialer Richtung über die äußeren 30% eines Radius (d¶0¶/2) des Rotors (20) erstreckt.
