Abstract
A laminated core segmentinto which a stator core is split has a core main bodythat extends in an arc shape. On one end section of the core main bodythere is formed a connecting section, and on the other end section there is formed a connecting section. The connecting sectionis able to connect with the connecting sectionof another laminated segment. In the connecting sectionthere is provided a protruding protrusion section, and the protrusion sectioninterferes with an interference sectionon the connecting sectionside when the stator coreis forced towards the direction in which the stator core is split. As a result, an assembly operation of the stator core becomes easier, and a magnetically excellent connecting structure can be obtained.
