A method for producing an electromagnetic component for an electric machine is provided. The method includes providing a metal sheet as a starting material; punching out a number of lamellae from the metal sheet; heat-treating the lamellae; and joining the heat-treated lamellae to form the component or a portion of the component. The electromagnetic component to be produced can be a laminated core, for example a stator core or a rotor core, and can be provided for use with the electric machine such as an electric motor.

Method for producing an electromagnetic component for an electric machine

The invention relates to a method for producing a lamination stack, e.g. a stator package or a rotor package. The method comprises the following steps: A) providing a metal sheet () with an adhesive coating; B) transporting the metal sheet in an in-line system comprising a cutting means (), a separating means () and an activation means (); C) cutting a molded part () with the cutting means (); D) activating the adhesive coating; E) separating the molded part (); F) placing the molded part (); G) repeating steps C) to F), wherein the adhesive coating of some molded parts () is provided with a treatment fluid by means of a treatment device () in order to allow for target breaking points for separating a molded part stack ('). In some cases a subsequent compaction can be carried out by a compaction station (). The invention also relates to a lamination stack and an electric machine.
