Electric motor comprising an interconnection ring and a stator having stator windings and an end cap, wherein the interconnection ring comprises a receiving part (1, 31) made of plastics material, wherein grooves extending in a circular manner that are oriented coaxially with one another and in which busbars are received are arranged on the axially upper side of the interconnection ring, wherein end regions, in particular end portions, of each stator winding wire of the stator of the electric motor are connected to contact portions of the electrical lines of the interconnection ring, wherein the contact portions are arranged radially externally on the interconnection ring, wherein connection portions extend from radially externally, where the junction to the relevant contact portion is located, to radially internally as far as to the radial position of the relevant busbar to be contacted, wherein each contact portion has detent levers by which a respective end region can be caught and retained in a frictionally connected manner, in particular clamped between the detent levers, wherein the catching-region opening produced by the detent levers of each contact portion is oriented in the circumferential direction, wherein recesses that are regularly spaced apart from one another in the circumferential direction and are configured as radially directed depressions are arranged on the outer circumference of the receiving part (1, 31), wherein the end cap comprises integrally shaped retaining portions having heads or pins, which project radially inwards and are provided as portions for engaging in the depressions on the radial outer wall of the interconnection ring, wherein the depressions are of a similar configuration and have the same depth in the radial direction, wherein the depressions extend from the edge of the interconnection ring initially in the axial direction and then also in the circumferential direction such that, when the interconnection ring is connected to the end cap of the stator, the interconnection ring is to be shifted in the axial direction and then rotated relative to the end cap in the circumferential direction, wherein the end regions of the stator winding wire face in the axial direction, are oriented substantially in parallel, are arranged at the same radial distance from the rotor shaft axis and are regularly spaced apart from one another in the circumferential direction, wherein the contact portions are shaped in a V-shape, a U-shape or a C-shape in such a way that, when the interconnection ring is rotated relative to the end cap, the end regions are caught in the inner region spanned by the contact portion, wherein each end region is electrically connected to a or to the detent levers of the contact portion by means of contact welding. comprising an interconnection ring and a stator having stator windings and an end cap, wherein the interconnection ring comprises a receiving part (1, 31) made of
