A wiring component is provided with a plurality of electric wires, and a holding portion that batch holds respective portions of the plurality of electric wires. The holding portion includes a holder that supports the plurality of electric wires in a predetermined positional relationship, and a resin mold portion composed of resin molded to cover the holder and the respective portions of the plurality of electric wires. The holder includes a substrate portion and a plurality of wire-holding portions formed protruding from the substrate portion. The plurality of electric wires are supported by the plurality of wire-holding portions, respectively. A notch or a through-hole is formed in the substrate portion corresponding to a portion into which molten resin is injected when forming the resin mold portion.

In a motor stator, terminal wires of a coil are led out respectively from a feed-side and a neutral-side coil end. With three circumferentially adjacent first-, second-, and third-phase coils as one set, the leading end portion and intermediate portion of one of three terminal wires led out from the neutral side are connected to each of the remaining terminal wires. A structure wherein the first- and second-phase terminal wires are connected together in one position, and the second- and third-phase terminal wires are connected together in a different position from the one position, is adopted, thus compacting the size of one wire connection portion.

A stator that includes an annular stator core having a plurality of slots and a plurality of coils attached to the stator core, the plurality of coils each including a main body that is inserted in the plurality of slots and includes two slot housed portions and coil end portions including oblique portions extending obliquely with respect to the axial direction, a radially first side end portion formed from one of the slot housed portions, and a radially second side end portion formed from the other one of the slot housed portions.

A device for positioning electrically conductive segments of a winding of a stator of a rotary electrical machine, including at least one rotative ring with at least one cam arranged around a revolution axis, the rotative ring being arranged to set in a radial motion at least two series of fingers to ensure the position of the conductive segments, wherein the two series of fingers are set in motion in opposite directions one to the other, such that a finger of a first series of fingers and a finger of a second series of fingers are configured to press two conductive segments of a pair of segments against each other.

The cold pressure welding apparatus includes a first holding part capable of sandwiching a first flat conductor, a second holding part disposed opposite to the first holding part and capable of sandwiching a second flat conductor, and a drive part for moving the first holding part and the second holding part. The drive part can move the first holding part and the second holding part between a first direction separated position and a close position along a first direction. The drive part can move the first holding part and the second holding part between a second direction separated position and a sandwiching position along a second direction.

In this stator armature, a first leg portion has a first surface side part that has a thickness in a radial direction smaller than a thickness of a first leg portion body portion in the radial direction, a second leg portion has a second surface side part that has a thickness in the radial direction smaller than a thickness of a second leg portion body portion in the radial direction, and in the radial direction, a thickness of a joint portion is equal to or more than a thickness of a part other than the joint portion.

A motor includes a rotor and a stator, a substrate electrically connected to the stator, a sheet-metal cover accommodating the stator and the substrate, and a wiring electrically connected to the substrate. The cover includes a through-hole open to a wall of the cover and communicating an outside and an inside of the cover. The wiring includes cables extending from the inside to the outside of the cover through the through-hole, and a bush with a tubular shape into which the cables are inserted, the bush being attached to the through-hole and elastically deformable. The cover includes a first cup body accommodating the stator and a second cup body accommodating the substrate. The bush is located radially between the second cup body and the substrate.

The present invention relates to an automatic motor lead wire cutting and twisting assembly which may include a rack, a turntable mechanism and a power control box which are both provided on the rack. On the rack surrounding the turntable mechanism are in turn provided a wire collating mechanism, a wire teasing mechanism, a wide cutting mechanism, a single cutting mechanism and a wire twisting mechanism. A wire teasing and securing mechanism is provided on the rack above the wire twisting mechanism. A reject tank is provided on the rack below the wide cutting mechanism and the single cutting mechanism. All of the drive components of the above mechanisms are electrically connected to the power control box. Cooperating with motor production equipment, an automated production line is formed, which mainly comprises turntable mechanism, wire collating mechanism, wire cutting part, and twisting part etc., with delicate structural design, high automation level, and time and human resource saving compared to manual operation, and conduces to improve production efficiency of motor production lines.

An insulation film peeling method which radiates laser light onto a front end portion of an insulation film-coated conducting wire including a conducting wire and an insulation film in a longitudinal direction, and which peels a part of the insulation film up to a peeling boundary of a predetermined regulated peeling length, includes performing a rectilinear scan of a first region, in which a radiation position of the laser light moves from one side toward the other side and then moves from the other side toward the one side upon reaching the other side, and performing a unidirectional scan of a second region, in which the radiation of the laser light is performed from one side toward the other side and then the radiation position returns to the one side in a state in which the radiation of the laser light stops upon reaching the other side.

An apparatus used in terminating and winding coils of a core of a dynamo electric machine. The coils being formed from at least an electric wire and the core having a longitudinal axis. The coils are wound by relatively moving a wire dispenser with respect to a core with relative motions of translation and rotation; at least a stretch of wire extends from the coil; and the stretch of wire is provided with a portion for a termination connection to a termination structure of the core, such as a tang. The method avoids waste cut wire in the apparatus. The core is provided with a groove at an end to receive at least a wire in the path of the wire for the termination of the coils. The apparatus comprises a wire deflector positioned adjacent the end of the core, where the groove is located, in order to intercept and align the wire with the groove. The apparatus can comprise a device for applying torques in two directions on a pulley wheel for feeding wire as a function of the position of the dispenser in the translation and the position of the core in the rotations.
