摘要： The present invention provides an automotive dynamoelectric stator that enables vibration resistance of a lead portion to be ensured and reductions in area of the lead portion and a coil end group that is exposed to a cooling airflow to be suppressed without increasing work or cost. In a dynamoelectric machine according to the present invention, first lead portions that connect a plurality of windings to configure phase windings are each led axially outward from a rear-end coil end group, and then disposed so as to extend parallel to an axially outer peripheral surface of the rear-end coil end group so as to cross at least one other first lead portion, and so as to be separated from the axially outer peripheral surface of the rear-end coil end group.

摘要： Respective divided segments of a collet are moved radially outward by moving an arbor axially. The respective divided segments thereby press an inner circumferential surface of a stator core of a stator from radially inside such that the stator is held coaxially by the collet. Next, shaping rollers are lowered so as to press an outer circumferential surface of the stator core. The stator is rotated by rotating the collet in that state. Thus, the inner circumferential surface of the stator core is compressed and plastically deformed so as to conform to the collet and the outer circumferential surface of the stator core is compressed and plastically deformed by the shaping rollers, correcting the inner circumferential surface and the outer circumferential surface of the stator core so as to be coaxial and so as to have a high degree of roundness.
摘要翻译：通过轴向移动心轴，夹头的相应分割段径向向外移动。相应的分割段从径向向内按压定子的定子芯的内圆周表面，使得定子由夹头同轴地保持。接下来，降低成形辊以按压定子芯的外周面。通过在该状态下旋转夹头来旋转定子。因此，定子铁芯的内周面被压缩并塑性变形，从而与夹头一致，并且定子铁芯的外周面被成型辊压缩并塑性变形，从而校正内周面和外周定子芯的表面以同轴的方式具有高度的圆度。

摘要： A cylindrical laminated body is prepared by winding into a helical shape a continuous first sheet formed by press-punching from a thin first magnetic steel sheet material. A second sheet having a predetermined length is prepared by press-punching from a thicker second magnetic steel sheet material. Next, chamfered portions are formed on edge portions of second recess portions by chamfering the second sheet. Then, the second sheet is bent into an annular shape and the second sheets bent into the annular shape are stacked on both axial ends of the laminated body and integrated by laser welding.

摘要： The stator core is configured into a cylindrical shape by abutting a laminated core that is obtained by bending and forming a rectangular parallelepiped lamination and integrating the stator core by welding. The lamination is configured by laminating a predetermined number of thin strip-shaped magnetic plates that are formed so as to have a flat rectangular shape, and in addition at least two thin sheet coupling weld portions that integrate the predetermined number of thin strip-shaped magnetic plates by welding are formed so as to extend from a first end to a second end in a direction of lamination on an outer wall surface of the lamination and so as to have a predetermined spacing in a longitudinal direction of the lamination. The stator core is formed such that an axial length A at the thin sheet coupling weld portions and a maximum axial length B between the thin sheet coupling weld portions satisfy an expression: 0.0 mm≦B·A≦0.2 mm.
