1. 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 connected to an interconnection unit assigned to the stator winding system,
wherein the winding chain has a pair of electric terminals for application of the electric current,
wherein the interconnection unit has paired contact points, by which the interconnection unit is electrically connectable to the at least two windings of the winding chain via the pair of electric terminals of the winding chain,
wherein the stator winding system comprises a sub-winding system corresponding to a phase of the electric current, wherein the sub-winding system has a number of winding chains connected in series in the current flow direction.
