Title (EN) BRUSHLESS MOTOR AND ELECTRICALLY POWERED TOOL
(FR) MOTEUR SANS BALAIS ET OUTIL ÉLECTRIQUE
(JA) ブラシレスモータおよび電動工具
Abstract:
(EN) A stator core 31 has an annular yoke 32 and a plurality of teeth 33 protruding from the inner peripheral surface of the yoke 32. An insulator 41 covers the yoke 32 and the teeth 33 to insulate the yoke 32 and the teeth 33 from a coil. A rotor 7 is disposed inside a stator core 31 with a predetermined gap provided between the rotor 7 and the front ends of the teeth 33. A protective member 20 is disposed between the yoke 32 and the rotor 7 and contains the rotor 7. The protective member 20 and the front ends of the teeth 33 form a closed space for containing the rotor 7.
(FR) Un noyau de stator 31 a une culasse annulaire 32 et une pluralité de dents 33 faisant saillie à partir de la surface périphérique interne de la culasse 32. Un isolant 41 recouvre la culasse 32 et les dents 33 pour isoler la culasse 32 et les dents 33 d'une bobine. Un rotor 7 est disposé à l'intérieur d'un noyau de stator 31, un espace prédéterminé étant prévu entre le rotor 7 et les extrémités avant des dents 33. Un élément de protection 20 est disposé entre la culasse 32 et le rotor 7 et contient le rotor 7. L'organe de protection 20 et les extrémités avant des dents 33 forment un espace fermé pour contenir le rotor 7.
(JA) ステータコア31は、環状のヨーク部32と、ヨーク部32の内周面から突出する複数のティース部33を有する。インシュレータ41は、ヨーク部32およびティース部33を覆って、コイル部から絶縁する。ロータ7は、ステータコア31の内側に、ティース部33の先端部と所定の間隔をあけて配置される。保護部材20は、ヨーク部32とロータ7との間に配置されて、ロータ7を収容する。ティース部33の先端部および保護部材20は、ロータ7を収容する閉空間を形成する。
