Title (EN) ROTARY DRIVE SOURCE FOR ELECTRIC ACTUATOR, AND ELECTRIC ACTUATOR
(FR) SOURCE D'ENTRAÎNEMENT ROTATIF POUR ACTIONNEUR ÉLECTRIQUE, ET ACTIONNEUR ÉLECTRIQUE
(JA) 電動アクチュエータ用回転駆動源および電動アクチュエータ
Abstract:
(EN) A position detection structure is provided with: a rotation side pulser ring having a magnetizing part for which N and S poles are arranged alternating along the circumference direction on the inner peripheral surface side; and a fixed side detection sensor that approaches and faces the magnetizing part of this pulser ring in the radial direction. The pulser ring of the position detection structure is overlapped in the axial direction at the inner diameter side of one of the axial direction end parts of the coil of the stator.
(FR) La présente invention concerne une structure de détection de position pourvue : d'une bague d'impulsion côté rotation ayant une partie de magnétisation pour laquelle des pôles N et S sont agencés en alternance le long de la direction de circonférence sur le côté de surface périphérique interne ; et d'un capteur de détection de côté fixe qui s'approche et fait face à la partie de magnétisation de cette bague d'impulsion dans la direction radiale. La bague d'impulsion de la structure de détection de position est chevauchée dans la direction axiale au niveau du côté de diamètre interne de l'une des parties d'extrémité de direction axiale de la bobine du stator.
(JA) 位置検出構造は、内周面側にN・S極が交互に周方向に沿って配設される着磁部を有する回転側のパルサーリングと、このパルサーリングの着磁部に径方向に近接対峙する固定側の検出用センサとを備える。位置検出構造のパルサーリングを、ステータのコイルの一方の軸方向端部の内径側において軸方向でオーバーラップさせた。
