    Abstract: The concentrated winding coil is mounted onto a tooth such that a coil end portion is housed inside a concave space that is formed by the trunk portion and first and second guide portions at two axial ends of the tooth. Third cover portions of an insulating sheet that is disposed on two circumferential sides of the tooth are folded over so as to overlap with each other and extend so as to cover the coil end portion of the concentrated winding coil, and a second leader line that projects outward from a radially inner end portion of the concentrated winding coil is bent and led radially outward parallel to the coil end portion that is covered by the third cover portions.

    Abstract: The present invention provides a dynamoelectric machine that suppresses the occurrence of insulation failure that accompanies oxidation of a stator core without lowering output, and that also suppresses stator temperature increases by transferring heat that is generated in a stator coil efficiently to a frame.A stator core is configured by laminating and integrating thin magnetic plates, and has an outer circumferential surface that has a cylindrical surface, and receiving grooves are formed on inner circumferences of openings of frames. The receiving grooves are constituted by: an annular axial surface that is constituted by a flat surface that is perpendicular to a central axis of the stator core; and a radial surface that is constituted by a cylindrical surface that is centered around the central axis. Metal surfaces of the thin magnetic plates at two axial ends of the stator core are held between each of the axial surfaces of the pair of frames in a state of close contact around an entire circumference.

    Abstract: 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.

    Abstract: 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.
