Abstract
An electric machine includes a plurality of planar laminations stacked to form an electrical steel rotor having openings defining magnet pockets and adjacent inner side pockets. The adjacent inner side pockets define a center bridge therebetween and have blasted surface portions such that compressive stress layers are induced along edges of the center bridge to strengthen the center bridge.
