摘要： A cylindrical laminated body is prepared by winding into a helical shape a continuous first sheet formed by press-punching from a thin first magnetic steel sheet material. A second sheet having a predetermined length is prepared by press-punching from a thicker second magnetic steel sheet material. Next, chamfered portions are formed on edge portions of second recess portions by chamfering the second sheet. Then, the second sheet is bent into an annular shape and the second sheets bent into the annular shape are stacked on both axial ends of the laminated body and integrated by laser welding.

摘要： The stator core is configured into a cylindrical shape by abutting a laminated core that is obtained by bending and forming a rectangular parallelepiped lamination and integrating the stator core by welding. The lamination is configured by laminating a predetermined number of thin strip-shaped magnetic plates that are formed so as to have a flat rectangular shape, and in addition at least two thin sheet coupling weld portions that integrate the predetermined number of thin strip-shaped magnetic plates by welding are formed so as to extend from a first end to a second end in a direction of lamination on an outer wall surface of the lamination and so as to have a predetermined spacing in a longitudinal direction of the lamination. The stator core is formed such that an axial length A at the thin sheet coupling weld portions and a maximum axial length B between the thin sheet coupling weld portions satisfy an expression: 0.0 mm≦B·A≦0.2 mm.
