Abstract:
(EN)
[Problem] To provide a rotation angle detection sensor that is low cost and can achieve increased compactness. [Solution] This rotation angle detection sensor (1) is provided with: a detection coil (20) such that a magnetic pathway (25) is formed within the coiling of a wire, the magnetic pathway (25) forming a partial torus; a mobile core (10) that advances/retreats with respect to the magnetic pathway (25) and is supported around a center of reciprocation in a manner able to reciprocate within a predetermined angular region; and a reciprocation arm (13) that supports the mobile core (10) in a manner able to reciprocate. When the core main body (11) of the mobile core (10) advances/retreats within the magnetic pathway (25), the inductance (L) of the detection coil (20) changes, and so the rotational angle can be detected by measuring the inductance (L).
(FR)
[Problème] L'invention a pour objet de mettre en œuvre un capteur de détection d'angle de rotation qui soit de faible coût et qui puisse réaliser une plus grande compacité. [Solution] L'invention concerne un capteur de détection d'angle de rotation (1) comportant : une bobine de détection (20) de sorte qu'une voie magnétique (25) est formée dans l'enroulement d'un fil, la voie magnétique (25) formant un tore partiel ; un noyau mobile (10) qui avance/rentre par rapport à la voie magnétique (25) et qui est supporté autour d'un centre à mouvement de va-et-vient de manière à pouvoir décrire un mouvement de va-et-vient dans les limites d'une région angulaire prédéterminée ; et un bras à mouvement de va-et-vient (13) qui supporte le noyau mobile (10) de manière à pouvoir décrire un mouvement de va-et-vient. Quand le corps principal de noyau (11) du noyau mobile (10) avance/rentre par rapport à la voie magnétique (25), l'inductance (L) de la bobine de détection (20) change, et ainsi l'angle de rotation peut être détecté en mesurant l'inductance (L).

【課題】低コストでかつ小型化を実現できる回転角度検出センサを提供する。 【解決手段】電線が巻き回される内側に磁路25が形成され、磁路25が部分円環状をなす検出コイル20と、揺動中心の回りに所定角度の範囲で揺動可能に支持され、磁路25を進退する可動コア10と、可動コア10を揺動可能に支持する揺動アーム13と、を備える回転角度検出センサ1。可動コア10のコア本体11が磁路25の内部を進退すると、検出コイル20のインダクタンスLが変化するので、インダクタンスLを計測すれば、回転角度を検出できる。
