Abstract

Ein Rotor einer elektrischen Maschine verfügt über einem scheibenförmigen Rotorträger (2) und einem zylinderringförmigen Rotorkern (3). Der Rotorträger (2) ist in axialer Richtung neben dem Rotorkern (3) koaxial zur Rotationsachse (11) angeordnet. Der Rotorkern (3) weist eine Ausnehmung (10) in axiale Richtung auf, die den Rotorkern (3) vollständig durchdringt und verfügt über Blechpakete (4a, 4b, 4c, 4d) mit jeweils einer Tasche (9) zur Aufnahme eines Permanentmagneten (6a, 6b). Ein Befestigungsbolzen (5) ist in der Ausnehmung (10) angeordnet und verbindet den Rotorkern (3) fest mit dem Rotorträger (2).
