Title (EN) ANGLE DETECTING DEVICE AND METHOD FOR MANUFACTURING THE SAME
(FR) DÉTECTEUR D'ANGLE ET PROCÉDÉ DE FABRICATION CORRESPONDANT
(JA) 角度検出装置及びその製造方法
Abstract: front page image
(EN)An angle detecting device includes a stator (200) provided with a plurality of salient-pole sections, which are formed as a flat board composed of a magnetic material and raised by bending process, and a wire winding member for excitation and a wire winding member for detection, with each salient-pole section as a wire winding magnetic core.  The angle detecting device also includes a rotor (300), which is composed of a magnetic material, and is rotatably arranged on the stator so that gap permeance between the salient-pole sections and the rotor changes by rotation in the rotating direction of the rotating axis. The angle detecting device has a largely reduced number of part items, reduced cost and improved reliability, without deteriorating detection accuracy.
(FR)La présente invention concerne un détecteur d'angle comportant un stator (200) équipé d'une pluralité d'éléments polaires saillants constitués d'une plaquette plate en matériau magnétique redressée par pliage, d'un enroulement excitateur et d'un enroulement détecteur, chaque élément polaire saillant constituant un noyau magnétique d'enroulement. Le dispositif de détection d'angle comprend également un rotor (300) constitué d'un matériau magnétique et monté rotatif sur le stator de façon que la rotation selon le sens de rotation de l'axe de rotation modifie la perméance d'entrefer entre les éléments polaires saillants et le rotor. Ce détecteur d'angle au nombre fortement réduit de pièces, s'avère moins cher et plus fiable, sans diminuer la précision de détection.
(JA) 本発明の角度検出装置は、磁性材料からなる平板に形成され折り曲げ加工により起こされた複数の突極部を有し、各突極部を巻線磁芯として励磁用の巻線部材及び検出用の巻線部材が設けられたステータ200と、磁性材料からなり、回転軸回りの回転により前記各突極部との間のギャップパーミアンスが変化するように前記ステータに対して回転可能に設けられたロータ300とを含む。  本発明の角度検出装置によれば、検出精度を低下させることなく、部品点数を大幅に削減し、低コスト化及び信頼性を向上させる角度検出装置を提供できるようになる。
