摘要： A method of manufacturing a stator 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 by more than one turn into a spiral shape; (3) forming a stator coil by assembling the rolled electric wires through elastic deformation thereof; and (4) assembling the stator core and the stator coil to form the stator. Further, in the rolling step, each of the planar electric wires is rolled by plastically deforming the turn portions into circumferentially-extending sections each having a predetermined curvature. Furthermore, a curvature ratio of a radially outermost one of the circumferentially-extending sections is set to be greater than that of a radially innermost one of the same.

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.
