Abstract:
An iron core of a rotating-electric machine, comprising:laminated magnetic plate strips, each of said strips connected to each other to form a substantially hexahedral laminate and, after being formed into said iron core, said substantially hexahedral laminate having a cylindrical core proximal portion; a plurality of teeth projecting in a substantially radial direction from the proximal portion; and slots for accommodating a winding that are located between the teeth adjacent to each other, wherein both end portions of the substantially hexahedral laminate are joined and curved so that the cylindrical core proximal portion obtains a predetermined curvature, the entire substantially hexahedral laminate is formed into a cylindrical shape, and distal ends of the teeth project from the cylindrical core proximal portion, and wherein said both end portions of the cylindrical core proximal portion of the laminate are at least one of a size, shape, and dimension that is different from a remainder thereof such that said both end portions have a lower rigidity than that of the remainder thereof.
