Stator of an electrical machine

Abstract

The present invention relates to a stator of an electric machine with a stator body having a stator axis, which stator body comprises stator grooves in which there runs an electric plug-in winding which is formed from multiple conductor elements (), conductor elements () being provided which each run with conductor branches through one or two of the stator grooves and protrude from the stator grooves on at least one end face of the stator by means of conductor ends () and form a winding head, the conductor ends () of the conductor elements () being arranged in the corresponding winding head in a plurality of groups () distributed in the circumferential direction in relation to the stator axis, each group () comprising a plurality of conductor ends () arranged in a radial direction in relation to the stator axis, in particular aligned in the radial direction, characterized in that at least one, in particular a plurality, of the conductor ends () of each group (), as viewed in the radial direction, has raised structures () arranged on both sides, in such a way that the raised structures () on a first side () of the conductor end (), when the entire group () of conductor ends () is clamped between two clamping jaws, permit the conductor end () adjacent to the first side () and the conductor end () having structures () to be approached towards one another elastically or plastically by the clamping jaws in order for the relevant conductor ends () to be welded, and, on an opposite, second side () maintain a distance between the conductor end () adjacent to the second side () and the conductor end () having structures () in order to prevent a welding of the relevant conductor ends ().
