Abstract

Die vorliegende Erfindung betrifft einen Rotor oder einen Stator für eine elektrische Maschine, mit einem Grundkörper, der Polschuhe aufweist, wobei im Grundkörper Dauermagnete angeordnet sind, die in den Polschuhen magnetische Pole bilden, und wobei zwischen jedem der Dauermagnete und einem an ihm angrenzenden Polschuh ein elektrisch leitender Schild angeordnet ist. Die vorliegende Erfindung betrifft weiterhin eine elektrische Maschine mit einem solchen Rotor oder Stator. Die vorliegende Erfindung betrifft weiterhin ein Elektroauto, ein Elektromoped oder ein Elektrofahrrad mit einer solchen elektrischen Maschine.
