点があった。The above-mentioned Japanese Patent Application No. 51-78066 has a conductive part d near the folded part of the coil wire corresponding to the tap of the cylindrical coil C, and a segment g of the coil holding plate A, as shown in the first figure.
The gist is to configure a tapless rotor by soldering the end of the cylindrical coil to the conductive part a, and in order to form the conductive part d, as shown in the second figure, a cylindrical coil is fed out from the coil bobbin 1 in the middle of winding. The tapped portion 3 of the coil wire 2 coated with urethane and adhesive is dipped in a solder bath 5 in which solder 4 is melted at about 400°C.
The heat of the solder melts and peels off the insulation double coating (urethane and adhesive) on the surface of the wire, and the solder covers the surface of the exposed conductor, and the conductive part coated with solder takes shape when taken out from the solder bath 5. Since the distance l to solder is long, the strands stretch and the part corresponding to the tap tends to shift, and the state of solder rising tends to vary, and the part corresponding to the soldered tap (conductive part) and the segment When connecting the edges, point contact is made as shown in the third diagram,
There is a drawback that the solder 6 becomes rounded due to surface tension, making the connection unstable.

うにしたものである。In view of these points, the present invention provides a tap-equivalent portion of the coil wire 2 coated with urethane and adhesive, which is sent out from the coil bobbin 1 during the winding of the cylindrical coil C, as shown in FIGS. 4 to 8. 3 is held between a hot rolling mill consisting of a diamond having a heater h and a punch 8, and the heat melts and peels off the insulation coating on the surface of the wire to expose the conductor, and the exposed conductor is rolled to form a flat conductive part d. The planar conductive portion and the end of the segment g are connected by solder 6 to integrate the cylindrical coil C and the coil holding plate A to form a rotor.
本発明によれば、タップ相当部が平担であるためセグメ

管理が容易となり、巻線途中でハンダ上げする必要がな
く製造工程が簡略化される効果がある。According to the present invention, since the tap-equivalent portion is flat, the connection point with the end of the segment makes surface contact, which stabilizes the joint connection, and since the flat conductive portion can be formed near the coil bobbin, misalignment of the tap-equivalent portion can be prevented. It can be made smaller, making it easier to manage the width of the portion corresponding to the tap, and eliminating the need for soldering in the middle of winding, which has the effect of simplifying the manufacturing process.
