Abstract:
1. A rotor of an electrical machine, comprising stator laminations in which a plurality of slots with internal widths are formed and which extend in a direction of a longitudinal axis of the rotor, wherein the internal widths of the slots are tapered on an inlet side to realize a reduction of the internal widths at the inlet side; a machine winding having winding overhangs; a cord lashing comprising a cord inserted into said slots and extending over said winding overhangs to form a netlike mesh thereon; and a filler element arranged so that at least one end of said cord is pressed by said filler element inserted in one of said slots in order to fix a position of said cord in an interstice of said one slot formed between said machine winding and a slot taper of said one slot, wherein the filler element is composed of a paper material and is shorter than a length of said one slot, wherein said cord and said filler element do not extend out of said one slot vertically above a surface of the stator laminations, and wherein said interstice is formed between said machine winding and said slot taper so that a material of said stator laminations proximate said slot taper is wider over regions of said machine winding in a manner of a roof.
