Title:
ELECTRICAL STEEL SHEET AND LAMINATED CORE
Document Type and Number:
Japanese Patent JP2021197491
Kind Code:
A
Abstract:
To provide an electromagnetic steel sheet that has sufficient adhesive strength and higher magnetic properties by optimizing the balance between the size of each bonded portion and the separation interval between these bonded portions, and a laminated core configured by laminating the plurality of electrical steel sheets.SOLUTION: An electromagnetic steel plat includes a base steel plate 2 and an insulating coating 3 formed on one or both sides of the base steel plate 2 and having adhesive ability, and the insulating coating 3 includes an organic resin phase 3a including at least one of an epoxy resin, a phenol resin, and a urethane resin, and a curing agent 3b1 arranged in the organic resin phase 3a in the form of spots, and the average circle equivalent diameter of each dot 3b in the form of spots is 0.1 μm or more and 5.0 μm or less.SELECTED DRAWING: Figure 5
