Abstract
【課題】異方性ボンド磁石及び環流穴を備える回転子の機械強度を確保し、欠けや割れが回転子に生じることを防ぐ。
【解決手段】コイルを備えるステータ4と、永久磁石7及び羽根車8を備えて回転自在に支持されている回転子2とを有して、射出成形で形成された上記回転子2の永久磁石が異方性ボンド磁石からなる。内周が軸受9を介して回転自在に支持される上記回転子は軸方向に貫通する環流穴11を備え、該環流穴11は、回転子の射出成形の際に生じるウェルド部13と異方性ボンド磁石である永久磁石の磁極間15とに重ならない位置に設けられている。割れや欠けが応力のかかりやすい環流穴付近で生じてしまうことがない。
