  • Publication number: 20230327528
    Abstract: In a method for producing a stator for an electric rotating machine, first material layers of a first metal material are produced from a green body by a sintering process. The first material layers of the first metal material are stacked to form a toothed arrangement comprised of a plurality of radially oriented teeth and an inner ring to connect the teeth. Each of the first material layers has a first thickness in a range of 10 ?m to 250 ?m, in particular in a range of 10 ?m to 100 ?m. Second material layers of a second metal material are stacked to form a yoke, with the first metal material having a saturation induction which is higher than a saturation induction of the second metal material. The yoke is joined to the toothed arrangement to form a material layer structure, and the inner ring is removed.
