Claims

[Scope of Claim for Utility Model Registration] (1) In a field core made of laminated thin iron core plates, the width of the body of the thin iron core plate is narrower than the width of the thin iron core plates laminated in the center. A circular arc surface is arranged on the outer circumferential side in the recesses at the four corners created by laminating several thin iron core plates laminated at both ends, the thin iron core plate at the center, and the thin iron core plates at both ends and the center. A field core for a rotating electric machine, comprising: a spacer having a cross section of approximately 1/4 circle, which is mounted as a spacer. (2) The field core for a rotating electric machine according to claim 1, wherein the spacer is made of either a metal material or an insulating molding material.
