Abstract:
When the number of risers (5) is, for example, 20, ten through holes (3c) are made in the boss (3a) of an armature core, and have a size large enough to view the backs of two adjacent risers through each hole (3c). After a sub-electrode (6a) is inserted into each of the through holes, a first main electrode (7a) is installed in contact with the first riser (5)(1 - (1)) of the first riser pair, and a second electrode (7a), in contact with the second riser (5)(6 - (2)) of the sixth riser pair. These risers are welded to the respective electrodes, and then, every other electrode of the rest main electrodes is welded to the corresponding riser, thus all the risers being welded to the electrodes.
