The present invention provides a winding having a structure in which a plurality of field windings are sequentially and continuously wound as shown in FIG. A detailed explanation will be given below based on FIG. 3. Here, the rectangular wire is defined as ``bending at a right angle in a non-plane of the rectangular wire'' to bend the flat part of the rectangular wire at a right angle, as shown in Fig. 3 (8 in the Pit diagram).

Further, as shown in 6 in FIG. 3(0), bending the rectangular wire at a right angle in the thickness direction l of the rectangular wire is hereinafter defined as "bending at a right angle within the plane of the rectangular wire."

In FIG. 3 (4), the starting end (■) of the flat wire is bent at a right angle within the plane of the flat wire (5). As is conventionally known, the first winding body (1) is wound in a predetermined number of layers by rotating the winding frame and feeding out the rectangular wire without pressing it against the winding frame of the winding machine. configured. The rolled state is shown in Figure 3 (B). Fix the wound first winding body with tape as shown in Figure 3 (C), remove it from the winding frame, and bend the middle part of the rectangular wire at right angles within the plane of the rectangular wire. 6), do not press this bending part 6 against the winding frame of the winding machine, but rotate the winding frame and feed out the flat wire (from 2), the second winding body (2) has a predetermined number of layered C two windings. The rolled state is shown in Figure 3 iD)C. Fix the wound wire body with tape and remove it from the winding frame.

As shown in Fig. 3 (E), the winding start part of the second winding body (2) is bent at a right angle within the non-plane of the flat wire (8) a then the middle part ■ t - Fig. 3 (F month = As shown, bend at right angle in the plane of the flat wire (9).Furthermore, the middle part ■ is shown in Figure 3 IG
