The present invention relates to a stator for an electric motor for use at very high temperatures of up to 550 ° C. The stator comprises a stator winding having an axis and having a plurality of winding wire ends guided out at a front end of the stator winding. Further, the stator comprises a Statorwicklungsverschaltung with a plurality of ring conductors, which are arranged coaxially to the front end of the stator winding and axially spaced from each other. The ring conductors are used for electrical contacting of the winding wire ends. According to the invention, provision is made in each case for an electrically insulating intermediate ring between axially successive ring conductors, wherein the ring conductors and the intermediate rings are alternately stacked on one another.
