Abstract

An active part of an electric machine includes electrical conductors which are additively printed in layers, and intermediate bodies respectively disposed between the electrical conductors and being additively printed in layers, wherein the electrical conductors are printed in a radially increasing manner, alternating with the intermediate bodies. A contact layer <=300 μm of a third material is applied between at least one of the electrical conductors and at least one of the printed intermediate bodies, with a diffusion zone being embodied by the contact layer and a heat treatment.
