Abstract

Die Erfindung betrifft eine elektrische Maschine, insbesondere einen Generator zur Speisung des Bordnetzes eines Kraftfahrzeuges, welche einen geblechten Stator (16) mit einer mehrphasigen Statorwicklung (18) und einen geblechten Rotor (20) aufweist, der an seinem Umfang durch mindestens eine Erregerwicklung (29) elektrisch erregte Pole (32,34) und vorzugsweise zusätzliche, durch Permanentmagnete (24,25) erregte Pole (33,35) besitzt. Die Rotorpole (32-35) sind dabei zumindest an ihrer bei Drehung von den Statorpolen (60) ablaufenden Kante (22) im Sinne einer Luftspaltvergrößerung geformt, wodurch eine deutliche Absenkung des magnetisch erzeugten Geräuschpegels der Maschine erreicht wird.
