PROBLEM TO BE SOLVED: To provide an iron core, a stator and a rotary electric machine which are small-sized, light-weighted and have good productivity.SOLUTION: An iron core 20 has: a plurality of split yoke parts 22: first teeth parts 24 extending inside in a radial direction from one end parts in a circumference direction of the respective split yoke parts 22; and second teeth parts 25 extending inside in the radial direction from the other end parts in the circumference direction. A tip part of the first teeth part 24 extending from one split yoke part 22 of two adjacent split yoke parts 22 is joined to a tip part of the second teeth part 25 extending from the other split yoke part 22 by a tip joining part 3K, so that the iron core 20 is integrally formed. By welding a welded part 6 provided on outer peripheral parts of the adjacent split yoke parts 22, the first teeth part 24 extending from the one split yoke part 22 of two adjacent split yoke parts 22 and the second teeth part 25 extending from the other split yoke part 22 constitute one teeth part 23.SELECTED DRAWING: Figure 6 |
