Abstract
A laminated pole for an electrical machine with salient poles is disclosed. The laminated pole includes a pole body having a plurality of pole sheets, and a pole end plate having a plurality of individual sheets. The pole sheets are layered and pressed one against another. The individual sheets are welded one to another, and may also be welded to a connecting pin. The connecting pin protrudes from the pole end plate in an axial direction and is used as a bearing or support member for a pole coil of the electrical machine. The individual sheets and the pole sheets are made from the same sheet material, have the same outside contour, and are punched with the same punching tool. Laminated pole end plates according to the present invention are cheaper to manufacture and suffer less pulsation losses and eddy current losses than solid pole end plates.
