Abstract

　本発明に係るリアクトル磁心は、Ｕ字状磁心と磁心脚部とで構成される環状のリアクトル磁心で、端部（１１ａ、１２ａ）と２つの突出部（２１ａ、２３ａ：２２ａ、２４ａ）からなる磁心継部（５ａ、５ｂ）がＵ字状磁心であり、これら磁心継部（５ａ、５ｂ）の突出部間に、磁心ブロック（３１ａ、３２ａ）からなる複数（２つ）の磁心脚部６が、突出部とギャップを有するように配置されている。磁心継部の突出部（２１ａ、２３ａ：２２ａ、２４ａ）の長さＡと磁心脚部を構成する磁心ブロック（３１ａ、３２ａ）の磁路方向の平均長さＢとの比Ａ／Ｂが０．３以上８．０以下となるように適切化されて、ギャップ部の漏れ磁束による銅損の増大が抑制される。
