Description
図1に本実施例のリアクトル装置を示す。このリアクトル装置は、トロイダル形状をなし、コア1と、コア1の外周に巻回された一対のコイル2と、から構成されている。このリアクトル装置は、ハイブリッド車のモータに配置され、コイル2への通電時に生じる磁束は図1に示す矢印方向となる。
ロールによる塑性加工を行わなかったこと以外は実施例と同様にして、円弧コア10及び直方体コア11を形成し、実施例と同様にしてリアクトル装置を製造した。このリアクトル装置では、粉末どうしが冶金的に結合された部分が無いので、渦電流の発生は未然に防止されている。しかし直方体コア11の辺(a)と辺(b)とにバリ11a が残り、円弧コア10の辺(d)にもバリがそのまま残っているため、コイル2の絶縁皮膜が損傷する恐れがあり、またバリから脱落したFe−Si粒子によってギャップ長が変化したり治具などが損傷する恐れもある。
直方体コア11の成形において、辺(a)と辺(c)とで囲まれた平面がプレス表面となるようにしたこと以外は実施例と同様にして、円弧コア10及び直方体コア11を形成し、実施例と同様にしてリアクトル装置を製造した。このリアクトル装置では、直方体コア11の辺(a)と辺(c)とで囲まれた平面の全周にバリが生じ、その全周で塑性加工によってFe−Si粒子どうしが冶金的に結合されている。また磁束は、直方体コア11の辺(a)と辺(c)とで囲まれた平面を透過する。したがって直方体コア11の辺(a)と辺(c)とで囲まれた平面には渦電流が発生し、リアクトル損失が大きくなってしまう。
本実施例のリアクトル装置の特性を確認するため、上記した3つの例のリアクトル装置についてリアクトル損失を測定した。結果を図5に示す。なお、リアクトル動作時の入力電力と出力電力との差分をリアクトル損失とした。

Claims (2)
- 圧粉磁心よりなるリアクトルコアと、該リアクトルコアの外周に巻回されたコイルと、よりなるリアクトル装置であって、
