    摘要: A stator includes a stator core, a stator coil comprised of a plurality of electric wires, and at least one restraint. Each of the electric wires has a plurality of in-slot portions received in slots of the stator core and a plurality of turn portions that are located outside of the slots to connect the in-slot portions. The restraint is mounted to end parts of the turn portions belonging to a turn portion group of the electric wires to restrain relative radial movement between the turn portions of the turn portion group. All the turn portions of the turn portion group protrude from the same slot of the stator core. The end parts of the turn portions respectively adjoin the in-slot portions of the electric wires received in the same slot of the stator core and align with each other in a radial direction of the stator core.

    摘要: A method of manufacturing a stator coil for an electric rotating machine includes the steps of: (1) forming substantially planar electric wires each of which includes in-slot portions to be received in slots of a stator core and turn portions to be located outside the slots to connect adjacent pairs of the in-slot portions; (2) rolling each of the planar electric wires through plastic deformation into a spiral or circular-arc shape; and (3) assembling the rolled electric wires together to form the stator coil. Further, in the rolling step, each of the planar electric wires is rolled by deforming each of the turn portions of the electric wire while restricting movement of at least one of the in-slot portions of the electric wire which is located closer to a rolling start end of the electric wire than the turn portion is.

    摘要: A stator includes an annular stator core having a plurality of slots arranged in the circumferential direction at predetermined intervals and a stator coil formed of a plurality of electric conductor wires mounted on the stator core. Each of the electric conductor wires has a plurality of in-slot portions received in the slots of the stator core and a plurality of turn portions that connect, on the outside of the slots, adjacent pairs of the in-slot portions. The stator coil has first and second coil end parts and that respectively protrude axially outward from a pair of axial end faces of the stator core. At each of the coil end parts, the turn portions of the electric conductor wires are stacked in a radial direction of the stator core, and the axial heights h1 of the turn portions are set so as to gradually increase from the radially inside to the radially outside.

    摘要: A method of welding a plurality of conductors to form a winding extending through an annular stator core. The conductors are inserted into slots formed in the stator core to have coil ends extending outside an end surface of the stator core. A plurality of pairs of the coil ends are arranged in diagonal arrays extending diagonally with respect to a radial direction of the stator core. The method inserts a first electrode into a gap between adjacent two of the diagonal arrays and then brings a second electrode close to one of the adjacent two of the diagonal arrays to arc-weld, the pairs of the coil ends. This welding method enables the welding of the coil ends arrayed in the above layout efficiently while keeping the electrical insulation between the pairs of the coil ends.
