Abstract

　この発明は、永久磁石の保持の信頼性を高め、組立工数が減らし、永久磁石の熱減磁を回避し、無負荷無励磁の誘起電圧を抑制できる回転電機を得る。 　この発明による回転電機では、第１及び第２磁石台座部が、第２及び第１爪状磁極部の各先端側の内周面に対向する第１及び第２継鉄部の部位に突設され、磁石収納部が、巻枠の一対のフランジ部の外周部から一体に軸方向外方に延設されて、第１及び第２爪状磁極部の各先端側の内周面に対向する第１及び第２継鉄部側に延在し、かつ第１及び第２磁石台座部に保持されている。そして、第１及び第２永久磁石が、第１及び第２磁石収納部に収納、保持されて、第２及び第１爪状磁極部の各先端側の内周面に対向して配置され、第１及び第２永久磁石のそれぞれは、界磁コイルの作る磁界の向きと逆向きに着磁配向されている。
