Abstract

An electric machine includes an electrical steel rotor having openings defining magnet pockets and outer side pockets, and having spaced apart axial stripes of increased compressive residual stress layers around a perimeter thereof. The outer side pockets and the perimeter form top bridges therebetween. Each of the axial stripes is aligned with one of the top bridges to strengthen outer edges of the top bridges.
