れることなく分布部に巻くことができる。According to the present invention, a plurality of cores are wound in a separated form around the head-side and tail-side crossover portions, and a multi-core parallel conductor is wound around the coil distribution portion. When winding the winding from the crossover portion to the coil distribution portion, the winding guide can be wound around the distribution portion without deviating from the coil distribution portion without the need for the winding guide as in the proposed example.
【００３０】また、渡り線部には多芯平行導線の形態に
なっていない複数の単線を巻くので、線の浮き上がりが
なく、線の捩じれも解消される。Further, since a plurality of single wires which are not in the form of a multi-core parallel conductive wire are wound around the crossover wire portion, the wire does not rise and the twist of the wire is eliminated.
【００３１】さらに、提案例のような高価な専用の巻線
