Abstract
A laminated iron core includes laminated iron core pieces, in which coupling parts are formed so as to communicate in a lamination direction of the laminated iron core pieces, and the coupling parts are filled with resins. The laminated iron core satisfies the following formula: (T×S)/η>{(4×E×δ×w×t)/L}×n, where T is a strength (N/mm) of the resin; S is a cross-sectional area (mm) of the coupling part or the resin; E is a Young's modulus (N/mm) of the strip material; δ is a distortion amount (mm) of the iron core piece; w is a width (mm) of the iron core piece in a radial direction; t is a plate thickness (mm) of the iron core piece; n is the number of laminated iron core pieces; L is a distance (mm) between the coupling parts adjacent in the circumferential direction; and η is a safety factor.
