    • A method of manufacturing a coil assembly of a rotary electric machine is disclosed wherein first and second coil wire segments are located on an axis direction in opposition to each other to allow first turn portions of the first and second coil wire segments to intersect with each other (in locating step). Engaging movement, composed of a forward transferring movement, a rotating movement and a translating movement, is conducted on the second coil wire segment with respect to the first coil wire segment to allow the first turn portion of the second coil wire segment to engage a second turn portion of the first coil wire segment (first engaging step). Conducting the engaging movement allows to engage a third turn portion of the first coil wire segment (second engaging step).
    • 公开了一种制造旋转电机的线圈组件的方法,其中第一和第二线圈线段相对于轴线方向定位,以允许第一和第二线圈线段的第一匝部分彼此相交 (在定位步骤)。 在第二线圈线段上相对于第一线圈线段进行接合运动,由正向转移运动,旋转运动和平移运动组成,以允许第二线圈线段的第一转弯部分接合第二线圈线段 第一线圈线段的转弯部分(第一接合步骤)。 进行接合运动允许接合第一线圈线段的第三转弯部分(第二接合步骤)。

    • Provided is a method of manufacturing a sequential segment joining type stator coil for use in an electric rotating machine, capable of achieving satisfactory electrical and thermal contact between end tip portion pairs of segments and basal electrodes and of realizing suitable welding even in the alignment of a large number of end tip portion pairs. For the arc welding of the end tip portion pairs of a sequential segment joining type stator coil, a large number of end tip portion pairs adjoining each other in a radial direction are held and pressed between basal electrode blocks. At this time, a circular-arc-like auxiliary electrode is put in a radial spacing between the end tip portion pairs. This not only enables the feeding to the end tip portion pairs lying at an intermediate position in the radial direction but also stabilizes the positions of the end tip portion pairs, and even reduces the heat radiation to an insulating coat of end skewing portions extending from the proximal portions of each end tip portion pair.
    • 提供了一种制造用于旋转电机的顺序段接合型定子线圈的方法,其能够在端部尖端部分对与基极之间实现令人满意的电和热接触,并且即使在对准 大量端头部分对。 对于顺序段接合型定子线圈的末端部分对的电弧焊,在径向方向上彼此邻接的大量端部尖端部对被保持并在基极电极块之间被按压。 此时,圆弧状辅助电极被放置在末端部对之间的径向间隔。 这不仅使得能够向位于径向中间位置的端部末端部分进给,而且还使得端部末端部对的位置稳定,并且甚至将热辐射降低到从顶端部对延伸的端部偏斜部分的绝缘涂层 每个末端部分对的近端部分。
