Abstract: The invention relates to an electrical machine (8), in particular an electric motor, suitable for the adjustment by external force of elements of a motor vehicle, essentially for driving a steering booster. The inventive electrical machine comprises a rotor (7) and a shaft (10), the rotor having a plurality of plates (5), wherein the plates (5) are premounted on the shaft either individually or as a plate assembly (6) or by means of a plurality of plate assemblies (6), the rotor (7) being connected to the shaft (10). The plates (5) have resilient lugs (3) for fixing the plates (5) and/or plate assemblies (6) to the shaft (10). Furthermore, the plates (5) of the plate assemblies (6) comprise centering lugs (1) which serve to radially center the plate assembly (6) relative to the shaft (10).

Abstract: The invention relates to a rotor or stator for an electric machine, in particular a spoke rotor which is arranged concentrically about a rotational axis and comprises a permanent magnet which is arranged in a recess of the rotor or stator. A spring strand for fixing the permanent magnet in the recess is provided in the rotor or stator, said spring strand comprising a holding ring and fixing means which are arranged on the holding ring. Said holding ring is arranged concentric about the rotational axis, and the fixing means extend in the axial direction of the rotor or stator into the recess. The holding ring is annular and the fixing means lie at least partially directly on the permanent magnets. The invention also relates to an electric machine comprising the claimed rotor. The invention further relates to a hand-held machine comprising a motor having a rotor or stator of the above-mentioned type.
