Abstract

Rotor (1, 1') für eine permanentmagnetische Maschine (14, 14')/ umfassend mehrere im Inneren des Rotors (1, 1') angeordnete, Pole (7) definierende Permanentmagnete (5), wobei - der Rotor (1, 1') aus wenigstens zwei koaxial aufeinanderfolgenden, denselben Radius aufweisenden, insbesondere gleichen, einzelnen Rotorscheiben (8) mit einer gleichen Anzahl von Polen (7) gleicher Ausdehnung in Umfangsrichtung besteht, - wobei die Rotorscheiben (8) jeweils durch wenigstens eine magnetischen Fluss zwischen den Rotorscheiben (8) vermeidende magnetische axiale Flusssperre (11) getrennt sind und - wobei die Pole (7) benachbarter Rotorscheiben (8) in Umfangsrichtung um einen vorgegebenen Versetzungswinkel, der kleiner als die Winkelausdehnung eines Pols (7) in Umfangsrichtung ist, gegeneinander versetzt angeordnet sind.
