本発明は、原コイルに絶縁テープを巻回した」二で、亀
甲形に成形する亀甲形コイルの製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a method of manufacturing a hexagonal-shaped coil in which an original coil is wound with an insulating tape and then formed into a hexagonal shape.

縁テープ３を巻回する必要があり、面倒であった。(Prior art) In the conventional hexagonal coil, the original coil was formed into the final shape, that is, the hexagonal shape, and then the insulating tape was wound around the hexagonal coil. When automating the winding work, a part of the tape winding device 4 may interfere with the coil end 2 when winding the insulating tape 3 around the coil end 2 of the hexagonal coil 1 as shown in FIG. This was unavoidable, and as a result, it was necessary to manually wrap the insulating tape 3 around the end 2 portions of the coil, which was troublesome.

下は避けられない。As a remedy for such defects, for example,
A manufacturing method as shown in Japanese Patent No. 5159 has been considered. According to this, after the original coil 5 is wound and formed into a hexagonal shape as shown in FIG. 5, the original coil 6.
The insulating tape 3 is wound spirally around the entire part except for between 6 and 6, and then formed into a hexagonal shape. In this case, since the portion 5a of the original coil 5 that becomes the coil end of the hexagonal coil has a relatively simple shape, it is also possible to automate the tape winding operation of this portion 5a. However, when forming the original coil 5 into a hexagonal shape after winding the tape, a corner portion 5c at the boundary between the portion 5a that will become the coil end and the portion 5b that will become the coil side after forming is After bending it back in the direction and making it into a straight line, it bends in the direction of arrow B, so the bending angle of the corner part 5c becomes large. There is a risk that the tape may shift and the insulating material such as mica on the surface of the insulating tape 3 may be damaged, and a significant decrease in the insulation properties of the corner portion 5c is unavoidable.

招いていた。(Problems to be Solved by the Invention) As mentioned above, in order to automate the tape winding work, an original coil is wound into a hexagonal shape and an insulating tape is wound around this original coil. Because the angle of bending back when forming into a tortoiseshell shape increases, the degree of displacement and damage to the insulating tape at that part is too large, resulting in a significant drop in insulation properties.

To provide a method for manufacturing a hexagonal coil that can maintain good insulation at a corner portion.

に巻回成形することを特徴とするものである。[Structure of the Invention] (Means for Solving the Problems) The manufacturing method of the present invention involves winding a strand of wire to form an original coil, wrapping an insulating tape around the original coil, and then winding the original coil into a hexagonal shape. In the method of manufacturing a hexagonal coil by molding, the original coil is wound and molded into a shape in which a portion that becomes a coil end of the hexagonal coil is connected in an arc shape from a linear portion that becomes a coil side portion. It is characterized by:

縁テープのずれが抑えられる。(Function) The shape of the original coil is such that the part that becomes the coil end of the hexagonal coil is connected in an arc shape from the straight part that becomes the coil side, so the part that becomes the coil end and the coil side The radius of curvature of the corner portion at the boundary with the straight line portion becomes larger. Therefore, when forming into a hexagonal shape, the angle at which the corner portion is bent back into a straight line is smaller than that of a conventional hexagonal original coil, thereby suppressing displacement of the insulating tape at the corner portion.

旋状に巻回されている。(Example) An example of the present invention will be described below with reference to FIGS. 1 to 3. As shown in FIG. 2, the shape of the hexagonal coil 11 that is finally formed is a shape in which curved coil end portions 13 and 13 are connected from mutually parallel linear coil sides 12 and 12. An insulating tape 15 is spirally wound around the entire portion except for the portion between the sunrise wires 14 and 14 led out from the coil ends 13 on the - side.

している。A method of manufacturing such a hexagonal coil 11 will be described below. First, as shown in FIG. 1, the original coil 17 is formed by winding the wire 16 around a winding form (not shown) having a predetermined shape. In this case, the shape of the original coil 17 is such that the portion 18 that becomes the coil side portion 12 of the hexagonal coil 11 is formed in a straight line, and the portion 19 that becomes the coil end portion 13 is connected in an arc shape from the linear portion 18. As a result, the radius of curvature of the corner portion 20 at the boundary between the linear portion 18 and the arcuate portion 19 is increased.

Note that the insulating tape 15 used is, for example, a tape based on glass fiber or resin film with an insulating material such as mica attached to the surface thereof.

１５表面の絶縁層の傷付きも抑えられる。Finally, the original coil 17 is formed into a hexagonal shape. During this molding, the corner portion 20 is bent back in the direction of arrow A to form a straight line, and then bent in the direction of arrow B, as shown in FIG. In this case, the radius of curvature of the corner portion 20 is increased by forming the portion 19 that becomes the coil end portion 13 in an arc shape from the straight portion 18.
The angle at which the corner portion 20 is bent back in the direction of the arrow is significantly smaller than in the past. For this reason, the corner part 20
Displacement of the insulating tape 15 is suppressed, and damage to the insulating layer on the surface of the insulating tape 15 is also suppressed.

Because it is rolled and formed, it is possible to reduce the angle at which a corner is bent back into a straight line when forming into a tortoiseshell shape, which prevents the insulating tape from shifting or being damaged at the corner.
Therefore, an excellent effect is achieved in that the insulation properties of the corner portion can be maintained well.
