PURPOSE:To eliminate the factor of an unbalance in a bell-shaped armature by simultaneously winding opposed coils to equally form the lengths of the opposed coils. CONSTITUTION:A coil 2 opposed to a coil 1 at an axis as a center are simultaneously wound, and a coil 4 opposed to a coil 3 are simultaneously wound thereon. Thereafter, coils up to 9, 10 are wound at equal angle while rotating to form the opposed coils of the same length.
