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).
Claims11
A method for producing a machine component (1) for an electrical machine, the method comprising
- forming the machine component (1) with a magnetically permeable material in which one or more magnetically impermeable separating regions (4) are provided,
- wherein the one or more separating regions (4) are formed by introducing a doping material (5) onto the magnetically permeable material, the doping material (5) having an austenite-forming material, wherein the doping material (5) is introduced during a melting process of the magnetically permeable material of the machine component (1), so that an austenitic structure is formed in the magnetically permeable material of the machine component (1);
- wherein the one or more separating regions (4) each includes opposite edges (36) of the machine component (1), the edges (36) spaced along a circumferential direction, wherein the edges (36) are connected to one another solely by the doping material (5).
