Abstract: Stator core of motor stator is equipped with a segmented core connecting body which connects in an annular shape a segmented core having a structure whereby laminated core plates are connected and held in place in a laminated state. To connect and fix core laminated plates by clamping, first and second dowels formed in each core laminated plate are used to connect and fix common rings by pressure-fitting them to the first and second end faces at either side of the segmented core connecting body, thus integrating the segmented core connecting body. The segmented core connecting body can be integrated with a simple operation, thus significantly reducing the assembly time for the stator core.
