The series coils arecomposed of forged copper conductors of rectangular armature core consists of punched disks of carefully an-nealed steel, held together between end plates. This core isbuilt upon an iron spider, which also carries the spider is pressed and keyed upon the extended shaftand may be drawn off without in any way interfering with the.
