Armature for an electric machine and method for producing the same
First Claim
1. An armature for an electrical machine in the form of an electrical starter, comprising:
- a ferromagnetic main body, wherein at least one axially extending groove is situated in the ferromagnetic main body, wherein in said groove, at least one electrical conductor is accommodated in a longitudinal groove length, further comprising at least one groove edge region element (8) formed and/or displaced by means of mechanical deformation of the main body (2) and acting upon the electrical conductor (4) for the purpose of defined positioning and/or fixation, wherein the groove edge region element (8) designed in the shape of a bridge comprises, before deformation, at least one notch (16).

Abstract
The invention concerns an armature for an electrical machine, in particular for an electrical starter, having a ferromagnetic main body in which at least one axially extending groove is arranged, in which said groove at least one electrical conductor is accommodated in the longitudinal groove length.
It is provided that the armature (1) comprises at least one groove edge region element (8) formed and/or displaced by means of mechanical deformation of the main body (2) and acting upon the electrical conductor (4) for the purpose of defined positioning and/or fixation.
The invention further concerns a method for producing an armature for an electrical machine.
