FIELD: electrical engineering.
SUBSTANCE: strip core has a main portion obtained by laminating a plurality of polygonal annular anisotropic electrical steel sheets in a side view, wherein the anisotropic electrical steel sheet has flat portions and curved portions that alternate continuously in the longitudinal direction, wherein at least one curved portion has a crystalline grain size Dpx in the anisotropic electrical steel sheet of 2W or less, where W is the width of the curved portion in the side view (mm).
EFFECT: minimized deterioration in efficiency due to the combination of the shape of the metal core in the steel sheet used.
