Title:
軟磁性金属粉末を用いたコア製造用単位ブロック、及び、該単位ブロックを用いた大電流直流重畳特性を有するコアの製造方法
Document Type and Number:
Japanese Patent JP2007509497
Kind Code:
A
Abstract:
A unit block for a core using soft magnetic metal powder, a core having excellent high-current DC bias characteristics using the unit block, and a method of producing the core are disclosed. The unit block is used to produce cores applied to an active filter for PFC, a three-phase line reactor, or an inductor for automotive electronics. A method of producing the core comprises mixing sendust alloy, High Flux, MPP, or silicon steel powders, which have an average particle size of 175 gm or less, with a solid lubricant; compacting a mixture at a pressure of 10-18 tons per unit area; heat-treating the compacted mixture at 600-800° C. for 1-2 hours to form the unit blocks each having a length of 3-10 cm, a width of 1-5 cm, and a height of 1-5 cm; and attaching the unit blocks using a heat- and fire-resistant adhesive.
