Patent ID: 8390166

Claim:
A segmented core motor stator comprising: a segmented core connecting body constructed by connecting a plurality of segmented cores in an annular shape, and a first ring fixed to one annular first end face in the segmented core connecting body; wherein each of the segmented cores is constructed from a plurality of laminated plates that are laminated together; a first dowel formed by pressing the laminated plates at identical points in identical directions along a lamination direction of the plates is provided to each of the laminated plates of each of the segmented cores; the plurality of laminated plates are connected and fixed in a laminated state by clamping and fixing the first dowels of the adjoining laminated plates to each other in the lamination direction; the first dowel protrudes from an outside end face selected from the first laminated plate and a second laminated plate positioned on both sides of the lamination direction in each of the segmented cores; the first end face of the segmented core connecting body is defined by the outside end face of the first laminated plate; a first dowel hole into which each of the first dowels can be pressure-fitted is formed in the first ring at a location corresponding to the first dowel protruding from the outside end face of the first laminated plate in each of the segmented cores connected in an annular shape; and the first ring is connected and fixed to the segmented core connecting body by pressure-fitting and fixing the first dowels in the corresponding first dowel holes.
