    摘要： A stator core is prepared into a cylindrical shape by abutting four arc-shaped laminated core divisions and welding an outer surface and an inner surface of the abutted portions. Each of the laminated core divisions is prepared by bending into an arc shape a rectangular parallelepiped laminated body formed by laminating thin magnetic plates. Second outer plate-joining weld portions are applied at positions dividing the outer surface of the laminated body into three sections, and first inner and outer plate-joining weld portions are applied to the inner surface and the outer surface in the vicinity of end portions of the laminated body.
