LAMINATED POLE FOR AN ELECTRICAL MACHINE WITH WELL-DEFINED POLES

摘要

A laminated pole for an electrical machine with salient poles is disclosed. The laminated pole includes a pole body having a plurality of first laminae, and a pole end plate having a plurality of second laminae. The first laminae are layered and pressed one against another. The second laminae 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 first and second laminae 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.
