Abstract

PURPOSE: To minimize the dispersion of iron core characteristics and also to make the iron core inexpensive by constituting the electromagnetic iron core by laminating an insulating film-free electromagnetic steel plate and an insulating film-coated electromagnetic steel plate on the surface.
CONSTITUTION: The electromagnetic iron core is manufactured by laminating the low-grade electromagnetic steel plate 13 the surface of which is provided with no insulating film and the electromagnetic steel plate 11 the surface of which is provided with the insulating film 12. In this case, the low-grade electromagnetic steel plate 13 without the insulating film is arranged in such a way that they are not in contact with each other and also its arranging order is from the outermost side. The iron core has the following features. The insulating film-free electromagnetic steel plate is manufactured easily and at lower cost and also capable of being annealed at high temperaures. And, since the insulating film-free electromagnetic steel plate is used in combination, the space factor can be increased. The iron core loss and B-H characteristic can be regulated according to the number of the insulating film-free electromagnetic steel plates used. In addition, since the insulating film-free electromagnetic steel plate is arranged in the outermost side, the heat radiability is good.
