ABSTRACT:
A laminated core formed by reliably and firmly connecting laminated core segments (10) in an annular form by first and second joining sections (19, 20) thereof, the first and second joining sections (19, 20) formed by alternately laminating sets of core segment sheets (21) and sets of core segment sheets (22), each set consisting of a predetermined number of sheets, the core segment sheets having brimmed concavities (24, 25) and brimmed convexities (23, 26) located at both ends of yoke-segment pieces (27, 36), wherein each laminated core segment (10) has round corners formed at both sides of a magnetic pole shaft section (12) and radially outward sides of a magnetic pole tooth section (13) at lower and upper laminated portions of the laminated core segment (10), thereby preventing damage to wires wound around the magnetic pole shaft section (12).
