Abstract:
A laminated core (100) has a plurality of legs having an extension direction in a direction perpendicular to a lamination direction of electrical steel sheets and a plurality of yokes having an extension direction in a direction orthogonal to the lamination direction of the electrical steel sheets and the extension direction of the legs, and, in the same position of the electrical steel sheet in the lamination direction, at least a partial region of the legs and at least a partial region of the yokes are configured by the same electrical steel sheet. The electrical steel sheet is disposed such that a first direction of directions of easy magnetization of the electrical steel sheet is along the extension direction of the legs and a second direction of the directions of easy magnetization of the electrical steel sheet is along the extension direction of the yokes.
