A lamination of a rotor of a rotary dynamo-electric machine includes a shaft bore with a radius, at least two pull-through grooves, and two intermediate space recesses. Each of the pull-through grooves has a lamination tongue facing radially inwards towards an axis such that the lamination tongue ends facing radially inwards lie on a radius which is smaller than the radius defined by the shaft bore.
