Abstract (en)

[origin: WO2021239177A1] The invention relates to a laminated core set (1) for a rotor (2), having at least one first laminated core (3) and at least one second laminated core (4), each having internal toothing (5) for fastening to a rotor shaft (6) and forming a magnet carrier, wherein the magnet carriers have recesses (7) for receiving magnets, wherein a circumferential orientation is a relative position between the recesses (7) and the internal toothing (5) of a laminated core (3, 4) and the circumferential orientation of the first laminated core (3) is different from the circumferential orientation of the second laminated core (4). The invention further relates to a rotor (2) for an electric machine having such a laminated core set (1) and a rotor shaft (6) to which the laminated core set (1) is attached such that the recesses (7) of axially adjacent laminated cores (3, 4) are arranged rotated by a predetermined angular offset.
