Producing Rotationally Symmetric Magnetic Sheets

Abstract

Various embodiments of the teachings herein include a method for producing a rotationally symmetrical magnetic sheet having a plurality of radially running winding teeth for a laminated core of an electric machine. An example includes: producing a green body by applying a printing paste onto a substrate using a stencil printing method, wherein the printing paste comprises binders and iron particles having more than 95 wt. % of iron; producing a preform from the green body using a first thermal treatment wherein the binders are removed from the green body; producing the magnetic sheet from the preform using a second thermal treatment including a sintering process; and pressing the magnetic sheet with a pressure of more than 5 MPa in a uniaxial manner in the sheet plane thereof with a pressing ram. The pressing generates an anisotropic texture in the winding teeth.
