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.
