Abstract | [Problem] The purpose of the invention is to provide a high performance, highly reliable, and highly versatile magnetostrictive member which is a single crystal but can be obtained at lower cost compared to conventional methods of manufacturing single crystals, and can be used for vibration power generation as a power source for drawing electric energy from various vibrations. [Solution] A magnetostrictive member which is formed by being cut from an Fe-Ga alloy single crystal by electrical discharge machining, the orientation of the alloy crystal being aligned in a direction in which magnetostriction of magnetostrictive elements is required.
Le problème de l'invention concerne un élément magnétostrictif haute performance, hautement fiable et hautement polyvalent, qui est un monocristal, mais qui peut être obtenu à un coût plus faible par rapport à des procédés classiques de la fabrication de monocristaux et qui peut être utilisé pour la génération d'énergie vibratoire comme source d'alimentation pour retirer de l'énergie électrique de diverses vibrations. La solution de l'invention porte sur un élément magnétostrictif qui est formé par découpe à partir d'un monocristal d'un alliage de Fe-Ga par usinage par électroérosion, l'orientation du cristal d'alliage étant alignée dans une direction dans laquelle la magnétostriction des éléments magnétostrictifs est requise.
【課題】 単結晶でありながら従来の単結晶製造方法よりも安価であり、種々の振動から電気エネルギーを取り出す電源としての振動発電に用いられる高性能で高い信頼性を有する汎用性の高い磁歪部材を提供することを目的とする。 【解決手段】 Fe-Ga合金の単結晶から、磁歪素子の磁歪を必要とする方向に前記合金の結晶の<100>方位を揃えて放電加工によって切り出して形成した磁歪部材。 |
