Abstract
The method for making a stator includes making individual strip-shaped laminas () for it; stacking the laminas () to form a stator core () with grooves () on one side extending through the core; producing a subassembly by inserting a stator winding () into the grooves (); bending the subassembly to form a cylindrical cavity so that the grooves () end in the cavity and connecting two ends () of the stator core () to each other by a welding seam () 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 (T) is given by T=0.5 mm*(H/mm−1)±ΔT, wherein His yoke height and ΔTis a tolerance value. An electric machine including the stator made by this method is also described.
