Abstract: A rotating electric machine includes a pair of electric conductors for forming a coil and a weld. Each of the electric conductors has an end portion with an end surface. The weld is formed between the end portions of the electric conductors at the end surfaces of the end portions. Moreover, the end portions of the electric conductors are arranged so that parts of the end portions of the electric conductors adjoin each other. At least one of the end portions of the electric conductors has at least one slit formed therein to divide the end surface of the end portion into a plurality of sections. The weld is formed to cover, at least, the adjoining parts of the end portions of the electric conductors and the at least one slit.

Abstract: A bobbin has a winding core and multiple partitioning walls, so that multiple winding areas are formed in an axial direction. A groove is formed in each of the partitioning walls, so that a wire rod strides over the partitioning wall bypassing through the groove when a winding process for one of the winding areas is finished and a winding process for a neighboring winding area will be started. The groove has a first and a second guide wall surfaces, which are opposed to each other in a circumferential direction. Each of the first and the second guide wall surfaces is inclined in the axial direction such that each of the first and the second guide wall surfaces comes closer to a circumferential winding-end side in the axial direction to a stride-end side.

Abstract translation: 线轴具有卷绕芯和多个分隔壁，使得在轴向方向上形成多个绕组区域。 在每个分隔壁中形成有凹槽，使得当绕组区域中的一个的卷绕处理完成并且将开始相邻卷绕区域的卷绕处理时，线材跨过通过凹槽的分隔壁。 所述槽具有在圆周方向上彼此相对的第一和第二引导壁表面。 第一和第二导向壁表面中的每一个在轴向方向上倾斜，使得第一和第二引导壁表面中的每一个在轴向方向上更接近于沿着前端侧的轴向的周向卷绕端侧。
