PURPOSE:To reduce the number of man-hour on assembly, by being rugged and spiral form in a circumferential direction with band plate cores formed continuously phase by phase and by forming a space between each phase. CONSTITUTION:So far as a band-plate-formed armature 2 is concerned, one phase is organized by one piece core having end points 4, 6 and being continuouly formed. The armature 2 is of a laminated structure in rugged and spiral form as a whole in a circumferential direction from the end point 4 the inermost section and is organized so that one piece core may be shifted outside through a shifting section 10 by being wound every turn. Three phase armatures are formed to be provided with sufficient insulating spaces 14 so that armatures 2a-2c independent phase by phase cannot be mutually short-circuited. |
