    • The present invention relates to a method that uses the so-called punching bundle-assembling technique for producing bundles of sheet iron having an iron core with a circular or oval cross-section. To this end, the laminates are punched from a strip while forming recesses on one side and protrusions on the other, wherein the protrusions are located opposite the recesses and conform to their shape. The protrusions are pressed into the recesses so as to form at least two circular warts when assembling each bundle. In each bundle, one laminate used as a separation laminate is formed with cylindrical holes instead of recesses for engaging the warts of adjacent laminates. The laminates punched from the strip exhibit different outer profiles and particularly different widths, and said laminates are attached together so as to form a bundle having an iron core with an at least partially circular cross-section. The bundle of sheet iron further exhibits stepped edges.
    • 利用本发明,提供了一种制造方法,这使得层叠铁心在提供所谓的Stanzpaketiertechnologie其具有圆形或椭圆形横截面的铁。 在这种情况下,可从一个条带翅片冲压出与所述凹部匹配的设置在一侧具有凹陷和在另一侧上和相对它们立面图,在至少两个圆形乳头形式的高程每个包的组装过程中被压入凹部。 在每个包装件作为分离层压薄片,圆柱孔被冲压,而不是凹槽,其中啮合在相邻的薄片的乳头。 这里被冲压出来的带材片,其具有不同的外部轮廓,特别是不同的宽度,并且连接在一起成至少部分地具有圆形铁横截面的包。 叠片铁芯具有锥形边缘。
