Abstract
A stator core capable of improving stator core segments in assemblability, positioning accuracy and rigidity is provided. A stator core includes a plurality of stator core segments, and a yoke part of each stator core segment has a first junction and a second junction joined to other adjacent stator core segments. A protrusion is formed at the first junction, and a recess capable of receiving the protrusion is formed at the second junction. The opening area of the recess increases from a deepest section of the recess to an opening of the recess. In the yoke part, a first caulking site where the stator core segment is caulked in an axial direction is formed on an arc passing through the central part of a radial length of the protrusion and extending in a circumferential direction.
