ABSTRACT:
An armature shaft for an electrical machine having a plurality of notches, extending along the circumference of the armature shaft essentially parallel to the longitudinal direction of the armature shaft, which notches form a notching heap. At least the notching heaps form acute angles whereby the imbalance of the armature directly after the shafts have been press-fitted into the lamination packet is reduced markedly. Moreover, the structure-borne sound of the motors is reduced compared to motors with stamped-out armature packets.
