Claim 6:
7. A method for producing a stator winding system for a stator of an electric machine, the stator winding system comprising a number of windings that are positionable on a number of stator teeth of the stator, respectively, wherein at least two windings of the number of windings that follow one another in a current flow direction of an electric current are connected in series, such that a winding chain is formed, and are formed from an electric conductor that is continuous in the current flow direction, wherein the winding chain is electrically connectable to an interconnection unit assigned to the stator winding system, wherein the stator winding system comprises a sub-winding system corresponding to a phase of the electric current, and wherein the sub-winding system has a number of winding chains connectable in series in the current flow direction, the method comprising:
producing a number of winding chains, the producing of the number of winding chains comprising shaping the continuous electric conductor for each winding chain of the number of winding chains, such that the continuous electric conductor forms the number of windings of the respective winding chain, wherein a winding chain of the number of winding chains has a first electrical terminal and a second electric terminal for application of the electric current; and
plugging the interconnection unit onto the first electrical terminal and the second electric terminal of the winding chain after the producing of the number of winding chains, such that the winding chain is electrically connected to the interconnection unit.
