Abstract
To counteract magnetic forces arising in the operation of a dynamo electric machine, and more particularly a vehicular, especially automotive three-phase alternator, causing, in operation, noise due to shifting of laminations under the influence of magnetic forces, the stator laminations are connected together at a circumferential edge, preferably the outer circumference, by a welding seam or track applied by laser welding. More than one seam or track may be provided, the welding seams or tracks extending in undulating or zig-zag form from one end face of the stack to the other in a criss-cross or mesh pattern.
