Similarly, in each of the first outer winding 71 to the fourth outer winding 74, a plurality of outer coil portions (two in this embodiment) are continuous between the one end side connection portion and the other end side connection portion. Is formed. Therefore, compared with the case where both ends of the inner coil portion and the outer coil portion are connected to the segment, the number of cuts and the number of turns of the conductive wire can be reduced. As a result, the processing time is shortened, and the cost can be reduced.

  In addition, since the number of conductors connected per 16 segments is one, fusing in the next process can be stabilized.

  Moreover, since the unnecessary part of a conducting wire is cut | disconnected after finishing winding of all the inner side coil parts (C1-C8) and an outer side coil part (C9-C16), the unnecessary part of a conducting wire is cut | disconnected during a winding winding process. Compared to cutting, the processing time can be shortened and the cost can be further reduced.

  The first and second embodiments of the present invention have been described above. However, the present invention is not limited to the above, and various modifications can be made without departing from the spirit of the present invention. Of course there is.

After connecting one end of the first conducting wire supplied from the one flyer to the 14th segment, the first conducting wire is concentratedly wound around the shaft portion of the sixth tooth to form the sixth coil portion. Then, the first conductive wire is concentratedly wound around the shaft portion of the fourth tooth to form the fourth coil portion, and the other end side of the first conductive wire is connected to the fifth segment. 3 Form the inner winding,
After connecting one end side of the second conducting wire supplied from the other flyer to the fourth segment, the second conducting wire is concentratedly wound around the shaft portion of the first tooth to form the first coil portion. Then, the first conductor is concentratedly wound around the shaft portion of the seventh tooth to form the seventh coil portion, and the other end of the second conductor is connected to the eleventh segment. A second inner winding winding step for forming four inner windings;
After connecting one end side of the first conducting wire supplied from the one flyer to the thirteenth segment, the first conducting wire is connected to the second branch portion of the sixth tooth and the first branch portion of the fifth tooth. The first coil is distributedly wound over the second branch portion of the eighth tooth and the first branch portion of the seventh tooth to form the thirteenth coil portion. After forming the 15 coil portion, the other end side of the first conducting wire is connected to the twelfth segment to form the first outer winding,
After connecting one end side of the second conducting wire supplied from the other flyer to the third segment, the second conducting wire is connected to the second branch portion of the first tooth and the first branch portion of the eighth tooth. The sixteenth coil portion is formed by distributed winding, and then the second conductor is distributedly wound across the second branch portion of the third tooth and the first branch portion of the second tooth to A first outer winding winding step of forming the second outer winding by connecting the other end of the second conducting wire to the tenth segment after forming 10 coil portions;
After connecting one end of the first conducting wire supplied from the one flyer to the ninth segment, the first conducting wire is connected to the first branch portion of the third tooth and the second branch portion of the fourth tooth. The eleventh coil portion is formed by distributed winding, and then the first conductive wire is distributedly wound across the first branching portion of the first tooth and the second branching portion of the second tooth. After forming the 9 coil portion, the other end side of the first conducting wire is connected to the 16th segment to form the third outer winding,
After connecting one end side of the second conducting wire supplied from the other flyer to the fifteenth segment, the second conducting wire is connected to the first branching portion of the sixth tooth and the second branching portion of the seventh tooth. The fourteenth coil portion is formed by winding over the second coil, and then the second conductive wire is distributed over the first branching portion of the fourth tooth and the second branching portion of the fifth tooth. A second outer winding winding step of forming the fourth outer winding by connecting the other end of the second conducting wire to the sixth segment after forming 12 coil portions;
A method of manufacturing an armature comprising: After the second outer winding winding step, a portion between the second segment and the fourteenth segment in the first conductor, a portion between the eighth segment and the fourth segment in the second conductor, A portion between the fifth segment and the thirteenth segment in the first conductor, a portion between the eleventh segment and the third segment in the second conductor, the twelfth segment and the first in the first conductor. A cutting step of cutting a portion between the nine segments and a portion between the tenth segment and the fifteenth segment in the second conducting wire;
The armature manufacturing method according to claim 7 .
