摘要： The rotor for an electrical machine comprises a plurality of stacked laminations (415). Each lamination (415) includes a plurality of radially extending slots (140) arranged about a circumference thereof and a first chamfer (520) on a surface (550) of each of the slots (140), wherein the surface (550) mates with a wedge (150). The first chamfer (520) connects the surface (550) and a first face (418) of the lamination (415). Advantage: Avoiding electrical contact between laminations due to smearing when the wedge mating surface (550) of the assembled rotor must additionally be machined.
