Abstract
A stator for an electric machine, having a winding including a plurality of interconnected conductors which are assigned to one or more phases, wherein: ends of at least some of the conductors project axially or radially beyond the winding. An interconnection ring having at least one support ring on which at least one bus bar is arranged is axially placed onto the winding, and the support ring is formed from a plastic and has concentrically extending annular grooves in each of which at least one bus bar is arranged. At least one end of a conductor is connected to a bus bar, at least one bus bar arranged in an annular groove is captively held in the annular groove by means of a bus bar securing element which overlaps at least portions of the annular groove in the radial direction, and the bus bar securing element as shaped by plastic deformation of a staking element which is formed integrally, in the axial direction from the support ring between two adjacent annular grooves, with the support ring.
