摘要： The method for making a stator includes making individual strip-shaped laminas (15) for it; stacking the laminas (15) to form a stator core (13) with grooves (18) on one side extending through the core; producing a subassembly by inserting a stator winding (17) into the grooves (18); bending the subassembly to form a cylindrical cavity so that the grooves (18) end in the cavity and connecting two ends (23) of the stator core (13) to each other by a welding seam (20) to maintain this configuration. To produce a welding seam of sufficient strength which does not exert excessive influence on magnetic properties, the welding seam depth (TS) is given by TS=0.5 mm*(Hyoke/mm−1)±ΔTS, wherein Hyoke is yoke height and ΔTS is a tolerance value. An electric machine including the stator made by this method is also described.

In another of the subsequent steps, the annular lamination packet (40) is plastically deformed in the axial direction (a) at least in some parts of the axial end surfaces (46). The present invention also proposes a stator for an electric machine, in particular a generator for motor vehicles, which is comprised of a stator yoke that is composed of rolled strip-shaped laminations (21) and has axial end surfaces (46). The stator yoke is plastically deformed in the axial direction (a) on the end surfaces (46). Finally, the present invention also proposes a stator for an electric machine, in particular a generator for motor vehicles, which has a stator yoke that is comprised of rolled strip-shaped laminations (21) and has axial end surfaces (46). The stator yoke has an axial length at its inner diameter that is greater than at its outer diameter.

摘要： The invention relates to an electrical machine having a stator winding, its manufacturing method and manufacturing apparatus, wherein the winding is manufactured with a predetermined number of coils on automated winding machines and is then embossed in the region of the longitudinal sides of the coils such that the longitudinal sides (17b), which have a plurality of conductors, of the coils (17), in terms of their cross section, are pressed and deformed into the subsequent slot shape. In order to achieve an extent of the coil conductors (18) without any intersections in the region of the longitudinal sides (17b) of the coils, the invention proposes first inserting the coils (17) in a preliminary embossing station (25) with their longitudinal sides into embossing chambers (23) of an embossing die (20), whose width corresponds to the width of at least two adjacent conductors, wherein the embossing chambers are then closed by an embossing stamp (26) to such an extent that, in the process, the conductors are aligned parallel to one another without any deformation of the cross section, before they are embossed into the final slot shape in a subsequent embossing station.
