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： An alternator can reduce the size of welding equipment and shorten the time of welding operation while ensuring high performance and high quality with the generation of electromagnetic noise being suppressed. The alternator includes a rotor having N poles and S poles alternately formed along a circumferential direction thereof, a stator core arranged so as to surround the rotor and having a plurality of axially extending slots formed at a predetermined pitch in the circumferential direction thereof, and a stator having a stator winding fitted into the slots. The stator core is formed by deforming by bending a hexahedral element iron core composed of iron core blocks with their adjacent ends being in abutment with each other and fusion bonded by welding. The weld portions of the blocks have a depth fusion extending at least up to a tensile region where a tensile stress of the stator core is generated.

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.
