METHOD FOR THE PRODUCTION OF A STATOR AND STATOR PRODUCED ACCORDING THERETO

摘要

A method for manufacturing a stator core (20) for an electric machine, in which a plurality of strip-shaped laminations (21) are first stacked to form an essentially block-shaped lamellas packet (40) that is then shaped into an annular form by means of roller bending in one of the subsequent steps so that the outer teeth are provided on the outer circumference of the lamination packets and has an axial direction (a) that corresponds to a cylinder axis (z), the annular form having axial end surfaces (46), wherein in another of the subsequent steps, the annular lamination packet (40) is plastically deformed in the axial direction (a) only on the outer teeth (70) of the axial end surfaces (46).
