PURPOSE:To reduce an intertap circulation current and to facilitate leading out of taps by a construction wherein 4 parallel conductors are divided into 2 groups each comprising 2 lines, these 4 conductors of 2 groups each with 2 lines are wound at the same time from the outer side to the inner side to form one set of disc-like coil section and from the inner side to the outer side to form another set of disc-like coil section, and these coils sections are disposed alternately in a continuous fashion. CONSTITUTION:In the figure, a0(#1)-a12(#8) conductors, a12(#1)-a24(#8) conductors, b0(#2)-b12(#4) conductors and b12(#2)-b24(#4) conductors are wound in parallel to form twin disc coils doubled in the axial direction of the coil disc. The a12(#1) and a12(#8) conductors and the b12(#2) and b12(#4) conductors are connected to each other, respectively, to serially connect the entire coil. The a24(#8) and b24(#4) conductors are directly led out to the fifth and sixth sections, respectively. In the fifth and sixth sections, one conductor is added to each of a24 and b24 conductors and 4-line parallel winding process which has been made in the first to fourth sections is repeated. |
