PROBLEM TO BE SOLVED: To provide a method and an apparatus for manufacturing a stator wherein it is possible to annularly arrange split cores with accuracy and facilitate maintenance. SOLUTION: Split cores 11 are annularly arranged on the outer circumference side of core metal 23 and an annular jig 22 is placed on the outer circumference side of the split cores 11 so that the entire split cores 11 are covered therewith. The outer tapered surface 25a of a shaft 25 and the inner tapered surfaces 24a of pressure tabs 24 are slid against each other by moving the shaft 25 upward in the axial direction. As a result, each pressure tab 24 is pressed outward in the radial direction and each split core 11 is moved outward in the radial direction by each pressure tab 24. Each split core 11, moved outward in the radial direction, is brought into contact with the inner circumferential surface 22d of the annular jig 22 and its outward movement in the radial direction is thereby arrested. At the same time, each split core is sandwiched between the inner circumferential surface 22d of the annular jig 22 and the outer circumferential surface 24d of each pressure tab 24. As a result, the split cores 11 are evenly pressed along the circumferential direction and annularly arranged with accuracy. COPYRIGHT: (C)2010,JPO&INPIT
