According to the winding method of single wire and single winding as shown in figure 1, the copper wire is wound from the inside to the outside after being scraped, and then wound around the second layer after six turns. At this time, it should be wound from the outside to the inside, and the position of each line in the second layer should be in the middle of the two lines in the first layer. After winding the second layer, wind the third layer from the inside out, as shown in the third layer diagram. After winding, hook the copper wire, then take it out, paint it with a utility knife, then hook it, and then wind it around the second pole, the roof of the world, in the same way. Remember to weld after winding.
The principle of double wire single winding is the same, except that the double wire is two parallel wires.
Figure 2 shows two lines, one is red and the other is blue. The winding method is the same as that of single wire.
