A conductor wire insulating film separating method disclosed includes: a preparing step involving preparing rectangular cross-section coil pieces each of which is a conductor wire coated with insulating film and used to provide a stator coil of rotary electric machine; a delivering-in step involving, after the preparing step, delivering coil pieces into a laser separator, with coil pieces aligned such that extremities thereof are adjacent to each other; an applying step involving, after the delivering-in step, continuously applying film removing laser to the extremities of the aligned coil pieces such that the laser is applied to one extremity and then to another extremity, thus removing at least portions of the insulating film from the extremities of the coil pieces; and a delivering-out step involving delivering the coil pieces, from which the at least portions of the insulating film have been removed by the applying step, out of the laser separator.

A cable such as a server cable may have a tapered termination portion that when connected to other information handling system components reduces the loss of signal between the cable and the information handling system component. A method of making a cable with a tapered termination portion comprising heating a wire having an end and a body portion, the body portion having a first diameter; pulling the end relative to the body portion, for example with a clamp coupled to the end under tension, to obtain a location between the end and the body portion having a second diameter smaller than the first diameter; and cutting the wire at the location.

A method for easy, safe and fast removal of a section of a cable film. An end section of a cable has a cable axis, wherein the cable includes a cable jacket and at least one electrically conductive conductor structure and which includes a cable film made from a plastic and applied into one of the conductor structures. A defined damaged region is generated by inductively heating at least that conductor structure on which the cable film is applied such that the cable film applied onto the heated conductor structure is at least partially thermally damaged in the damaged region. The cable film is moved relative to one of the conductor structures, wherein a crack is formed by the relative movement in the damaged region that separates the section of the cable film to be removed from a section of the cable film remaining on the cable.

An electrical conductor for a rotating electrical machine wound component includes a body formed of an electrically conductive material and a coating layer formed of an electrically insulating material, the coating layer partially covering the body. The conductor is formed of a first portion, referred to as the main portion, in which the body is covered by the coating layer, a second portion, referred to as the intermediate portion, in which the body is covered with residue of the coating layer, and a third portion, referred to as the stripped portion, in which the body is bare. The intermediate portion is arranged between the main portion and the stripped portion.

The method and apparatus comprise the following features: —forming coil members (21) by bending an electric conductor (20) externally coated with an outer insulation (20′); wherein the bending is made at predetermined lengths from a reference position (16′), and wherein each one of the coil members (21), when formed, comprises at least one head portion (21′) and leg portions (21″) extending from said at least one head portion (21′); —feeding the electric conductor (20) to accomplish the bending; —cutting the electric conductor (20) to detach a formed coil member (21) from said electric conductor (20); —inserting the leg portions (21″) of the coil members (21) into slots of the stator, so that parts of said leg portions (21″) extend from one end of the stator and the head portions (21′) extend from an opposite end of the stator; —arranging at least one laser beam (13′a, 13′b) to remove the insulation (20′) from predetermined areas (20a, 20b) of the electric conductor (20); —radiating the surface of the electric conductor (20) with said at least one laser beam (13′a, 13′b) situated at a predetermined position (IP, 2P) with respect to the reference position (16′) along the length of the electric conductor (20) being fed, and at a predetermined stage of the bending of a coil member (20).

An embedded wire removal tool is disclosed. The embedded wire removal tool can include a feed mechanism operable to cause movement of a cable. The cable can have a jacket about a core. The cable can also include a wire disposed about the core and at least partially embedded in the jacket. The embedded wire removal tool can also include a jacket cutter operable to receive the cable from the feed mechanism and remove at least a portion of the jacket. In addition, the embedded wire removal tool can include a wire excavator operable to separate the wire from the core.

Disclosed is an apparatus for peeling a coil of a motor, including a pallet on which the coil is mounted; a conveying part formed long in a lengthwise direction and configured to convey the pallet; a clamper located at the side surface of the conveying part and formed to be movable toward the conveying part and to fix the tip portion of the coil; and a laser irradiating part located at a side surface of the conveying part to radiate laser at a peeling work spot and to peel a coating layer of a tip portion of the coil. Therefore, a bonding force between the coil and the bus bar can be easily increased.

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 embedded wire removal tool is disclosed. The embedded wire removal tool can include a feed mechanism operable to cause movement of a cable. The cable can have a jacket about a core. The cable can also include a wire disposed about the core and at least partially embedded in the jacket. The embedded wire removal tool can also include a jacket cutter operable to receive the cable from the feed mechanism and remove at least a portion of the jacket. In addition, the embedded wire removal tool can include a wire excavator operable to separate the wire from the core.

One aspect pertains to a method for producing an ablated wire, including providing a coated wire having a circumference and a length. The coated wire has a core, an outermost coating layer, and an outer surface. The outermost coating layer at least partially surrounds the core. A plurality of laser beams are provided.
