Abstract

The invention relates to a method for producing a machine component (1) for an electrical machine, wherein the machine component (1) is formed with a magnetically conductive material, in which one or more magnetically nonconductive separating regions (4) are provided, wherein the separating region (4) is formed by the introduction of austenite-forming material during a melting process of the magnetically conductive material of the machine component (1), such that an austenitic structure is formed in the magnetically conductive material of the machine component (1).
