PROBLEM TO BE SOLVED: To obtain an inexpensive, high efficiency armature of dynamo-electric machine having excellent insulation performance by suppressing occurrence of damage on the insulating coating of a conductor wire, due to rubbing of the armature core and armature winding, while suppressing increase in the number of components and thinning of a magnetic pole teeth, and to provide a manufacturing method therefor.SOLUTION: A stator 10 includes a stator core 11 consisting of an annular yoke, and a large number of magnetic pole teeth arranged in the circumferential direction while projecting radially inward from the yoke, respectively, and a stator winding 20 consisting of a plurality of winding bodies 22 attached to the stator core 11. The stator core 11 is composed of three short cores 112, where at least one region continuous in the circumferential direction has two magnetic pole teeth, and the circumferential section between the regions is composed of one long core 111 longer than the short core 112. |
