1. A stator for an electric motor comprising:

  • a stator winding with an axis and with several winding wire ends which are passed out at a front end of the stator winding, wherein the stator comprises a stator winding interconnection with several ring conductors which are arranged at the front end of the stator winding coaxially to same and are axially spaced apart from each other, wherein the ring conductors serve the electrical contacting of the winding wire ends, and wherein an electrically insulating distance ring is respectively provided between axially successive ring conductors, and wherein the ring conductors and the distance rings are alternately stacked,wherein the stator comprises a winding support ring, wherein the winding support ring is arranged between the stator winding and the stacked ring conductors and includes several bores through which the winding wire ends are passed,wherein the stator winding is supported in the radial direction by a supporting sleeve arranged inside the stator winding, the supporting sleeve being inserted into an accommodating recess of the winding support ring,wherein the winding support ring is directly adjacent, in an axial direction, to a front end of the stator winding on a first side of the winding support ring, andwherein the stator winding interconnection is surrounded by a ring sleeve, and the ring sleeve is joined to the winding support ring on a second side of the winding support ring, opposite the first side.
