Abstract

Ein Rotor (11) für eine elektrische Maschine (1) umfasst eine Basis (110) mit einem konzentrisch zu einer Rotationsachse (R) angeordneten Magnetaufnahmebereich (111), der mehrere Aufnahmetaschen (112) ausbildet, die um die Rotationsachse (R) herum abwechselnd näher zur Rotationsachse (R) und weiter weg von der Rotationsachse (R) angeordnet sind, und mehrere Magneten (12A; 12B), wobei jeweils zumindest oder genau ein Magnet (12A; 12B) in jede der Aufnahmetaschen (112) eingesetzt ist.
