Abstract

The invention relates to a stator (IO) in an electric machine (I) with a laminated core (II) formed in an annular fashion about a central axis (A), on which core stator coils (16) with coil ends (16a, b) are arranged by means of formers (12a, 12b). The stator (IO) comprises wiring device (20), on which a plurality of mutually isolated connecting conductors (22-26) with coil connection areas (22a-26a) are present for connecting the stator coils (16). The wiring device (20) is joined on the stator in an axial joining direction to the stator coils (16) and is secured by axial connection means (30a, b) to the formers (12a), thus forming a plurality of axial connections (32a, b). According to the invention, to increase the stiffness of the stator (IO), radial supporting means (40, 41) are additionally formed on the wiring device (20) to interact with the formers (12a), said means being designed to be functionally independent of the axial connection means (30a, b).
