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

Laminated core and method for manufacturing the same

A apparatus for carrying spherical objects is adopted, which comprises: a housing 1; a cylindrical rotor 6 arranged in the housing, including a plurality of recess grooves 11 which are open to the outer circumferential surface, the plurality of recess grooves being arranged radially from the center of the rotor 6; a guide ring arranged in the housing, the guide ring 3 including an inner hole 5, the section of which is elliptical, in which the cylindrical rotor 6 is accommodated; a vane 12 slidably arranged in each recess groove 11; a first carrier atmosphere feeding pipe 16 connected with a converting section of the guide ring 3 in which the inner hole 5 is changed from a small diameter section to a large diameter section; a first carrier atmosphere discharging pipe 17 connected with a converting section of the guide ring 3 in which the inner hole 5 is changed from a large diameter section to a small diameter section; a second carrier atmosphere feeding pipe 18 connected with a converting section of the guide ring 3 in which the inner hole 5 is changed from a small diameter section to a large diameter section; and a second carrier atmosphere discharging pipe 19 connected with a converting section of the guide ring 3 in which the inner hole 5 is changed from a large diameter section to a small diameter section.
