MAGNETIC CIRCUIT Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: magnetic circuit is composed of reeled band of magnetic alloy and hardened adhesive made fast to it. Adhesive fulls partially interturn space of core, volumetric portion of core bonded with adhesive amounts to 0.01-0.9. Versions of invention present fillings by adhesive of inner turns, inner and outer turns, alternation of zones filled with hardened adhesive and free of it, impregnation of butt surfaces of core. Alloys based on iron and cobalt having not less than 80% of amorphous structure as well as alloy based on iron in which not less than 50% of crystalline grains have size 100 nμ are proposed for manufacture of band of magnetic alloy. EFFECT: enhanced stability of operational characteristics. 12 cl, 1 dwg
