Method for producing a multilayered magnet

A method for producing a multilayered magnet with a plurality of first layers and a plurality of second insulating layers which follow one another alternately, the method comprising:

• applying material having magnetic material and a binder by injection molding to a base plate to form a first layer of a green body at a thickness of at least 1.5 mm and at most 4 mm;
• applying further material by injection molding to form a second insulating layer of the green body adjacent to the first layer at a thickness of at least 0.01 mm and at most 0.1 mm, with the further material being an electrically poorly conducting material with an electrical conductivity which is between 1·10−8 and 1·10−14 S/m;
• and/or forming the second insulating layer by oxidizing a surface of the first layer through application of an oxidizing agent;
• and/or forming the second insulating layer by applying the binder by injection molding.

A magnet comprising:

• a plurality of first layers having a thickness of at least 1.5 mm and at most 4 mm;
• and
• a plurality of second insulating layers having a thickness of at least 0.01 mm and at most 0.1 mm, with the plurality of first layers and the plurality of second insulating layers following one another alternately,
• wherein the first layer of a green body is formed by applying material by injection molding to a base plate, with the material having magnetic material and a binder, and
• wherein the second insulating layer of the green body is formed by applying further material by injection molding adjacent to the first layer, with the further material being an electrically poorly conducting material with an electrical conductivity which is between 1·10−8 and 1·10−14 S/m and/or wherein the second insulating layer is formed by oxidizing a surface of the first layer, with the surface of the first layer being oxidized by applying an oxidizing agent and/or wherein the second insulating layer is formed by applying the binder by injection molding.
