A rotor lamination is subdivided into a plurality of equidistant sectors of equal size, each including a first half-sector and a second half-sector separated from the first half-sector by a separation plane. A through-opening is formed in the first half-sector and has a first leg side, of which the imaginary extension intersects the separation plane below a radially outwardly open acute angle, a second leg side, which runs parallel to the first leg side and of which the imaginary extension intersects the separation plane radially further outwards than the imaginary extension of the first leg side, and an edge connecting ends of the leg sides furthest away from the separation plane. A further through opening formed mirror-symmetrically to the first through-opening with respect to the separation plane is formed in the second half-sector, wherein the edge has an equidistant portion equidistant to an outer contour of the rotor lamination.
