摘要： A rotor for an electric machine, such as an electric motor, includes a pack of stacked rotor laminations (60). A sheet metal section of the rotor laminations (60) has guide webs (61) and open intermediate spaces (62). Raised areas (63) at the one side of each rotor lamination (60) correspond to indentations at the opposite, other side and form connecting bodies that extend in the axial direction and form-lockingly engage into an adjacent rotor lamination. Radial thrust forces are transferred from one rotor lamination (80) onto the adjacent rotor lamination.
