Abstract

In a method for producing an electric metal sheet for an electric machine, an individual sheet is punched out from a magnetizable sheet blank. A plurality of cut-outs are formed in the individual sheet; and a web is applied in each of the cut-outs by a 3-D printing process from a non-magnetizable material, such that the webs are arranged either in parallel relation to a first q-axis at a pre-determined spacing from the first g-axis, or a first plurality of the webs is arranged exclusively on a first circular segment defined by a first radius and a second plurality of the webs is arranged exclusively on a second circular segment defined by a second radius which is different in relation to the first radius.
