Abstract
Rotors or stators of this kind are cut out from rolled sheet metal with a predominant magnetic direction and are stacked to form a rotor or stator lamination bundle. In order to largely compensate for a magnetic anisotropy of the rotor or stator lamination packet, when the sheet metal blanks are asymmetrical (A, B), they are cut out from the rolled sheet metal rotated in relation to one another with regard to the predominant magnetic direction. The process according to the invention can be used for electric machine rotors or stators comprised of sheet metal blanks.
