Claim 0:
1. A rotor lamination, comprising:
a plurality of equidistant sectors into which the rotor lamination is equally divided, each of the plurality of equidistant sectors including
a first half-sector,
a second half-sector separated from the first half-sector through a separation plane,
a first through-opening formed in each of the first half-sector and the second half-sector and having
a first leg side, a first imaginary extension extending on the first leg side and intersecting the separation plane (4) at a first radially outwardly open acute angle,
a second leg side apart from and parallel to the first leg side, a second imaginary extension extending on the second leg side and intersecting the separation plane radially further outwards than the first imaginary extension of the first leg side, and
an edge connecting ends of the first and second leg sides furthest away from the separation plane, and having
an equidistant portion circumferentially extending equidistant from an outer contour of the rotor lamination, and
a first transition portion extending between the first leg side and the equidistant portion and including
 a projection projecting into the first through opening,
 a first straight portion extending from the projection and parallel to the first imaginary extension, and
 a rebate extending opposite to the projection from the first straight portion,

wherein the first through opening of the second half-sector is formed mirror-symmetrically to the first through-opening of the first half-sector with respect to the separation plane,
the rebate extends between the first straight portion and an imaginary line apart from and parallel to the first leg side and intersecting the separation plane radially further inwards than the first imaginary extension of the first leg side, and
a distance between the imaginary line and one end of the projection projecting into the first through-opening is at least 1.1 times of a distance between the imaginary line and the first imaginary extension of the first leg side.
