摘要： An electrical machine circuit element (1) comprises a flat metal sheet (2) provided with a plurality of slots (3) for an electric and/or cooling circuit. The elements (1) presents a plurality of clips (5) which project from the flat metal sheet (2) and a plurality of seats (7) to receive and retain clips (5) of other elements (1), in such a manner as to connect several elements together. Each clip (5) projects from one face of the metal sheet (2) and defines a seat (7) on the opposite face. The clips (5) present an edge (11) facing into the slots (3).

摘要： The laminar article (1) for electrical use comprises a plurality of superposed first metal laminations (2) fixed together. Each of the first laminations (2) is provided with at least one fastener (3, 3a, 3b) projecting from a first surface (4) thereof and defining a recess (5, 5b) in its opposite side. Each fastener (3, 3a, 3b) of one lamination (2) is arranged to fit into a recess (5, 5b) of an adjacent lamination. The article presents second laminations (9) interposed between at least two adjacent first laminations (2) fixed together. The second laminations (9) are provided with through apertures (10) which are traversed by the fasteners (3, 3a, 3b) which fix the adjacent first laminations together. The method consists of die-cutting a plurality of laminations from a metal sheet, rotating the die-cut laminations and superposing them, to then fix them together in predetermined manner. The laminations can be die-cut with a reference axis thereof rotated through a predetermined angle about a reference axis of the metal sheet, to limit the rotations to be imposed on the laminations during their mutual fixing.
摘要翻译：用于电用的层流制品（1）包括固定在一起的多个重叠的第一金属叠片（2）。每个第一叠片（2）设置有从其第一表面（4）突出并在其相对侧限定凹部（5,5b）的至少一个紧固件（3,3a，3b）。一个层压体（2）的每个紧固件（3,3a，3b）被布置成装配到相邻层压体的凹部（5,5b）中。本文介绍了介于固定在一起的至少两个相邻的第一叠片（2）之间的第二叠片（9）。第二叠片（9）设置有贯穿孔（10），所述通孔通过将相邻的第一叠片固定在一起的紧固件（3,3a，3b）横穿。该方法包括从金属片上切割多个叠片，旋转冲切叠片并叠加它们，然后以预定的方式将它们固定在一起。叠片可以被模切，其参考轴线围绕金属板的参考轴线旋转预定角度，以限制在相互固定期间施加在叠片上的旋转。

摘要： The laminar article (1) for electrical use comprises a plurality of superposed first metal laminations (2) fixed together. Each of the first laminations (2) is provided with at least one fastener (3, 3a, 3b) projecting from a first surface (4) thereof and defining a recess (5, 5b) in its opposite side. Each fastener (3, 3a, 3b) of one lamination (2) is arranged to fit into a recess (5, 5b) of an adjacent lamination. The article presents second laminations (9) interposed between at least two adjacent first laminations (2) fixed together. The second laminations (9) are provided with through apertures (10) which are traversed by the fasteners (3, 3a, 3b) which fix the adjacent first laminations together. The method consists of die-cutting a plurality of laminations from a metal sheet, rotating the die-cut laminations and superposing them, to then fix them together in predetermined manner. The laminations can be die-cut with a reference axis thereof rotated through a predetermined angle about a reference axis of the metal sheet, to limit the rotations to be imposed on the laminations during their mutual fixing.
