Method for producing a material layer and a material layer structure for a dynamoelectric rotary machine

A method for producing a shaped material layer having an outer perimeter and a centrally arranged substantially round material cut-out, without further machining, said method comprising:

• providing a template having an annular cutout complementary to the outer perimeter of the shaped material layer and to the centrally arranged substantially round material cut-out of the shaped material layer,
• applying, with a scraper, a suspension with a binding agent and solid particles through the template onto a base area for obtaining a green body having the outer perimeter and the centrally arranged substantially round material cut-out and a layer thickness between 0.5 and 500 μm,
• driving the binding agent out of the green body, in particular by debindering;
• and
• creating a permanent cohesion of the solid particles by at least one of heating, compaction, and sintering, thereby producing the material layer with the outer perimeter and the centrally arranged substantially round material cut-out and the layer thickness between 0.5 and 500 μm without further machining.
