Abstract:
A component unit for an electric machine includes an annular lamination stack formed of a plurality of axially stacked laminations. The lamination stack is secured by an inner or outer cylindrical fastening portion to a cylindrical receiving portion of a carrier element. The carrier element has two stops between which the lamination stack is axially clamped in a frictionally engaging manner. At least one of the axial stops has an annular supporting element arranged at the receiving portion and supports the lamination stack and which is fixed at the carrier element by at least one caulking region.
