Abstract

PURPOSE: To devise an improvement of magnetic characteristics by adhering end surfaces of legs and yoke irons piled up with sheet irons by adhesives containing magnetic powders.
CONSTITUTION: End surfaces of legs 12aW12c piled up with sheet irons 12 respectively and yoke irons 13a, 13b piled up with sheet irons 13 respectively are butt jointed and these junction portions are adhered by adhesive 14 containing magnetic powders. Adhesives containing magnetic powders have a stability for a temperature rise of a junction portion and are used those having a desired permeability using such as epoxy-resin etc. of high adhering strength in which reduced iron powder of high purity, sprayed iron powder or magnetic powder such as of silicon containing iron are kneaded. In this manner magnetic reluctances are decreased than those of joints of sheet irons of legs and yoke irons simply butt jointed such as customary used general iron cores and together with improving characteristics, a noise due to a magnetic distortion is decreased as junction portions are adhered as one body.
