Abstract: front page image
(EN)To reduce part count, thus cost, by forming a supporting member of an armature integrally with a stationary member, as well as to secure a sufficient magnetic attractive force by preventing a magnetic path via a supporting point from being generated, by making the supporting member in a cantilever structure. Variability in an amount of gap between the armature and the stationary member is reduced and the magnetic characteristic is stabilized by providing the supporting member on the stationary member.
(FR)Cette invention se rapporte à la réduction du nombre de pièces, et donc du coût, en formant d'une pièce un élément de support d'une armature avec un élément fixe, ainsi qu'à l'obtention d'une force d'attraction magnétique suffisante en empêchant la création d’un chemin magnétique par l'intermédiaire d'un point de support, en donnant à l'élément de support une structure en porte-à-faux. La variabilité de la quantité d'entrefer entre l'armature et l'élément fixe est réduite et la caractéristique magnétique est stabilisée en disposant l'élément de support sur l'élément fixe.
(JA)アーマチュアの支持部を固定子と一体に形成することで部品数を削減して安価にするとともに、上記支持部を片持ち構造として支点部を介した磁気経路が生じないようにすることで十分な磁気吸引力を確保する。支持部を固定子に設けることでアーマチュアと固定子とのギャップ量のばらつきが減少し、磁気特性が安定する。
