摘要： An electric wire shaping apparatus is provided for shaping an electric wire for a stator coil of an electric rotating machine. The electric wire includes a plurality of straight portions and a plurality of turn portions. Each of the turn portions includes a specific part and all of the specific parts of the turn portions are identical to each other. The apparatus includes a clamping mechanism, first and second holders, and a shaping mechanism. The clamping mechanism clamps the specific part of one of the turn portions of the electric wire in a width-wise direction thereof. The first and second holders respectively hold two different sections of the specific part in a thickness-wise direction thereof. The shaping mechanism moves one of the first and second holders relative to the other in the thickness-wise direction of the specific part, thereby shaping the specific part to form a crank-shaped portion therein.

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 producing a coil assembly to be wound in a stator core with a plurality of slots. The method prepares a first and a second coil wire each of which is made up of in-slot portions and turned portions, arranges the first and second coil wires in parallel with the turned portions being offset from each other in a lengthwise direction thereof, moves the first coil wire to establish engagement of the turned portions of the first and second coil wires, turns the first coil wire about a pivot where the turned portions engage, crosses the first coil wire over the second coil wire around the pivot, and turns the first coil wire around the pivot so as to twist the turned portions of the first and second coil wires together. This sequence of steps is repeated to twist or braid the first and second coil wires without undesirable deformation thereof.

摘要： Disclosed is an apparatus for rolling a substantially planar electric wire by more than one turn into a spiral shape. The apparatus includes an inner pressing member having an outer surface, an intermediate pressing member having radially inner and outer surfaces, and an outer pressing member having an inner surface. The inner and intermediate pressing members together press a first part of the electric wire between the outer surface of the inner pressing member and the inner surface of the intermediate pressing member, thereby plastically deforming the first part to extend along the outer surface of the inner pressing member. The intermediate and outer pressing members together press a second part of the electric wire between the outer surface of the intermediate pressing member and the inner surface of the outer pressing member, thereby plastically deforming the second part to extend along the outer surface of the intermediate pressing member.

摘要： A method of manufacturing a coil assembly unit comprises steps of coil forming, weaving, compressing steps. In the forming step, each coil wire is formed which provides linear portions and turn potions each connecting linear portions, during which bent portions are formed at both ends of each linear portion, the bent portions being bent so that mutually adjacent linear portions are deviated from each other. In the weaving step, the coil wires are mutually woven in turn, in which the turn portions intersect in turn. All the coil wires are subjected to the weaving step in turn to produce a woven coil assembly. In the compressing step, the woven coil assembly is compressed by compressing the woven coil so that each bent portion is deformed to be linear to allow the mutually adjacent linear portions to come closer to each other, thus producing the coil assembly unit.
