<p>PROBLEM TO BE SOLVED: To provide a stator manufacturing method able to reduce the circularity of a core inner peripheral surface in the case where a plurality of core pieces are arranged in an annular form to compose a stator core.SOLUTION: A stator manufacturing method comprises an arranging process, pressing process, holding process, and attaching process. The arranging process uses an inner support member 30 composed such that a cylindrical support face F can be reduced in diameter while a cylindrical support face F follows a complete circle as viewed in an axial direction L. In the arranging process, a plurality of core pieces 20 are arranged in a cylindrical form such that the respective inner peripheral surfaces 20a of the core pieces 20 follow the support face F. In the pressing process, after the arranging process, the support face F is reduced in diameter by applying pressing force directed inside in a radial direction R, with respect to all the core pieces 20. In the holding process, the positions of the core pieces 20 are held while the pressing state by the pressing process is maintained. In the attaching process, a regulating member 90 is attached to the core pieces 20 while the positions of the core pieces 20 are held by the holding process.</p> |
