    Abstract: Thin sheets of magnetic material are subjected to a pressing process to stamp many sheets of core pieces, and caulking projections defined in the core pieces are caused to go into connecting through holes defined in the core pieces for connecting and laminating to produce a laminated core. In lower layer of the core pieces having the caulking projections arranged in different positions seeing in plan, at least two sheets of core pieces and other core pieces having the connecting through holes are provided. The caulking projections defined in the core pieces have projecting length of at least twice of thickness of the core pieces, and are fitted in the connecting through holes, so that upper and lower laminated core pieces are unified.

    Abstract: A method of producing a laminated core of a stator of an electric motor, includes at least one laminated core of a stator formed by stacked sheet-metal laminates, which have mechanical individual poles and of poles connected in the circumferential direction of the stator, at least one pole shank and at least one pole shoe facing a rotor. The sheet-metal laminates are configured with indentations and protrusions and, as a result, the sheet-metal laminates form the laminated core of the stator by interengagement of the indentations and protrusions. The mechanical poles of the laminated core of the stator have windings, and webs are provided between the poles to connect the connected mechanical poles in the circumferential direction. The axial set-up of the sheet-metal laminates of the laminated core of the stator has a predeterminable alternating succession of poles with a connecting web and poles without a connecting web.

    Abstract: A laminated rotor for an induction motor has a plurality of ferro-magnetic laminations mounted axially on a rotor shaft. Each of the plurality of laminations has a central aperture in the shape of a polygon with sides of equal length. The laminations are alternatingly rotated 180° from one another so that the straight sides of the polygon shaped apertures are misaligned. As a circular rotor shaft is press fit into a stack of laminations, the point of maximum interference occurs at the midpoints of the sides of the polygon (i.e., at the smallest radius of the central apertures of the laminations). Because the laminates are alternatingly rotated, the laminate material at the points of maximum interference yields relatively easily into the vertices (i.e., the greatest radius of the central aperture) of the polygonal central aperture of the next lamination as the shaft is inserted into the stack of laminations. Because of this yielding process, the amount of force required to insert the shaft is reduced, and a tighter fit is achieved.

    Abstract translation: 用于感应电动机的层压转子具有轴向安装在转子轴上的多个铁磁性叠片。 多个叠片中的每一个具有呈多边形形状的具有相等长度的边的中心孔。 叠片交替地彼此旋转180°，使得多边形孔的直边不对准。 由于圆形转子轴被压配合成叠片，所以最大干涉点出现在多边形侧面的中点（即在叠片的中心孔的最小半径处）。 由于层叠体交替旋转，所以当最大干涉点处的层压材料插入到堆叠中时，相对容易地进入下一叠层的多边形中心孔的顶点（即，中心孔的最大半径） 的叠片。 由于这种屈服过程，减少了插入轴所需的力的量，并且实现了更紧密的配合。
