Abstract
Methods for tuning properties of electric machines are disclosed. A method for reducing core loss in an electric machine includes punching a plurality of laminations from one or more electrical steel sheets that results in one or more cut edges. The method further includes assembling the laminations into a core such that an outer perimeter surface of the core is defined by the cut edges. The method further includes peening the outer perimeter surface to remove residual stresses.
