As shown in Figure 4, coils traditionally used to generate magnetic fields are made by winding a hollow conductor with a hole inside the copper wire into a coil, and water can be passed through the hole to directly cool the conductor. It has a structure. Coils using this material have a higher cooling effect than coils using other conductors. Therefore, the amount of current that can be passed through this conductor can be made larger than that of other conductors, and the cooling efficiency improves as the number of channels in the coil is divided and increased, and a large current can be passed even with the same cross-sectional area of the conductor. can.

あつた。 Generally, the number of channels in a coil is the largest, and it is divided by the number of layers in the coil. However, Fig. 3 a, b
As shown in the figure, if the coil (one pancake) of one channel is made into four layers with 6 turns per layer and a total of 24 turns, the ends of each conductor are wound at the beginning of 7, 8, 9, and 9 for each layer of the coil. and 10, the end of winding is 77,
Since the windings 88, 89, and 101 are located on both sides of the coil, such windings are not preferable if there are spatial constraints on the processing of the coil terminals. Therefore, as shown in Figure 2 a and b, a two-layer, 12-turn, one-channel coil (W pancake) is stacked in two layers so that all the terminals are gathered on one side. . In this case, the winding starts of the two coils are indicated by 5 and 6, respectively, and the winding ends are indicated by 55 and 66, respectively. However, in the W pancake structure, the conductor length is twice that of a single pancake coil, so the friction of flowing water inside the hollow conductor is doubled.
Since the water flow is reduced, the cooling effect is correspondingly poor, and when using the same capacity power source, the cross-sectional area of the conductor in the W pancake needs to be larger than that of the one pancake, and the hollow part needs to be thicker, so the overall coil The drawbacks were that the pancakes were larger and the cost was higher.

In order to eliminate these drawbacks, the present invention allows all the coil terminals to be brought out to one side of the coil, thereby saving space for processing the terminals.Moreover, the coil can be cooled with a cooling efficiency equal to or higher than that of a coil wound in a single pancake. It is an object of the present invention to provide a method of winding a coil which is small in size and advantageous in cost, and which can reduce the cross-sectional area.

Examples of the present invention will be described below. In other words, in Figure 1 a and b, the inner W pancake is wound in two layers using two hollow conductors constituting the coil at the same time, and the W pancake is further wound in the same way on the outside. This shows a coil equivalent to 4 layers stacked with 6 turns per coil for a total of 24 turns. In reality, the number of turns per conductor is two W pancakes stacked in parallel in two layers with three turns per layer, and four six-turn coils are stacked to form the whole. This is the conventional coil winding method shown in Figure 2 a, b and Figure 3 a, b.
First, as shown in Figure 1 a and b, the ends of each coil are numbered 1, 2, 3, and 4 at the beginning of the first coil, and 11, 22, and 33 at the end of the coil. , and 44, all gathered to one side, which is the same as in FIGS. 2a and b, and the length of each coil is half this, which is the same as in FIGS. 3a and b.

面積は一段と小さいものの使用が可能となる。 Therefore, each coil terminal is gathered on one side of the coil, which is advantageous in terms of terminal processing space, and the frictional resistance of the water flow is half that of the coils shown in Fig. 2 a and b, which can be processed with the same terminal processing, improving the cooling effect and improving the cooling effect of the coil. It becomes possible to use a material with a much smaller cross-sectional area.

It becomes possible to provide an efficient and cost-effective winding method. Generally, the same effect can be obtained by using multiple hollow conductors and winding them into an even number of layers. For example, for n hollow conductors, one 1/n
If the coil is wound in multiple layers, its ends will always gather on one side of the coil. Electrically, by connecting the end and beginning of a coil divided into n pieces, a single connected coil can be obtained.
