Patent ID: 8683675

Claim:
A method for fabricating a molded stator of a rotary electric machine, in which: a coil is wound on a divided laminated core composed of a plurality of core pieces that are laminated; a plurality of the divided laminated cores are circularly joined; and the outer circumferential surfaces of the plurality of divided laminated cores are molded and fixed, the method comprising: a lamination step of preparing a plurality of core sheets in which core pieces used in the same lamination layer of the divided laminated cores are connected to a joining portion via bridge portions respectively connected to middle portions of the outer circumferences of back yoke portions of the core pieces, and laminating the core sheets to form a divided-laminated-core group structure; a winding step of winding the coil on a teeth portion of each divided laminated core of the divided-laminated-core group structure; a cutting step of cutting the bridge portions of the divided laminated cores wound with the coils, thereby separating the divided laminated cores from the divided-laminated-core group structure; a temporary fixing step of forming a stator by circularly arranging the divided laminated cores that have been cut, and temporarily fixing the outer circumferential portion of the stator; and a molding step of inserting an axial rod having a diameter equal to the inner diameter of the stator, into the stator along the inner circumferential surface of the stator, placing the stator into which the axial rod has been inserted, in a mold, and molding an outer circumferential surface of the stator with resin.
