摘要： A wire forming apparatus comprises a first rack moveable relative to a second rack in a first direction, a plurality of first forming structures provided on the first rack, and a plurality of second forming structures provided on the second rack. Each of the plurality of first forming structures is configured to move in the first direction, is separated from an adjacent first forming structure, and is configured to move in a second direction closer to the adjacent first forming structure when the first rack moves relative to the second rack. Each of the plurality of second forming structures is configured to move in the first direction, is separated from an adjacent second forming structure, and is configured to move in the second direction closer to the adjacent second forming structure when the first rack moves relative to the second rack. The second direction is different from the first direction.

摘要： A casting device having a casting mold and a core for producing a helical casting is described. The may have an expendable core that can be dissolved after the casting process. Advantageous effects of the device and process can be achieved by virtue of the fact that the female mold for accommodating the helical casting during the casting process is formed completely within the outer contour of the core, the female mold being delimited by the core and, at the peripheral boundary surfaces of the female mold, by the casting mold.

摘要： A stator has a stator core composed of teeth and slots. Segment coils are inserted into the corresponding slots. The segment coil projecting from the slot has an exposed conductor part and a covered conductor part covered with an electrical insulation film. The exposed conductor part is arranged at the distal end side from the covered conductor part of the segment coil. The segment coils are connected together through the exposed conductor parts thereof projecting from the slots. The exposed conductor part has a thickness T2 thinner than a thickness T1 of the covered conductor part. A step part is formed at a position of the stator core side, adjacent to the exposed conductor part of the segment coil. The step part and the covered conductor part are covered with the electrical insulation film continuously from the stator core side of the covered conductor part.

摘要： A conductor shaping apparatus includes a driving device that relatively rotates an upper die and a lower die and integrally rotates the two dies with respect to a shaping member. The driving device rotates one of the upper and lower dies in a direction from an edgewise bent portion to a distal end of a conductor. One of the upper and lower dies includes a supporting surface configured to support a side surface of an end portion of the conductor as the edgewise bent portion is formed in the end portion, and a guide surface that is formed to intersect the support surface. The guide surface extends away from the end portion of the conductor in a direction opposite to a bent direction of a flatwise bent portion closest to the edgewise bent portion as it extends away from the supporting surface on an opposite side of a rotational axis.
