Abstract:
(EN) This linear actuator 40 for an endoscope is provided with: a movable frame 42 formed from a magnetic body; a stationary frame 43 which has provided therein the movable frame 42 so that the movable frame 42 can move forward and backward, and which is formed from a non-magnetic body; two coils 44, 45 formed and wound on the outer surface of the stationary frame 43 and arranged side by side in a longitudinal axis direction; a permanent magnet 46 disposed in a stacked manner so as to overlap the two coils 44, 45; and two yokes 47, 48 arranged in front of and behind the permanent magnet 46 and the two coils 44, 45.
(FR) Cette invention concerne un actionneur linéaire 40 pour endoscope comprenant : un cadre mobile 42 constitué d'un corps magnétique ; un cadre fixe 43 qui contient le cadre mobile 42 de façon que le cadre mobile 42 puisse se déplacer vers l'avant et l'arrière, et qui est constitué d'un corps non magnétique ; deux bobines 44, 45 formées et enroulées sur la surface externe du cadre fixe 43 et agencées côte à côte dans le sens de l'axe longitudinal ; un aimant permanent 46 dans une relation empilée de manière à chevaucher les deux bobines 44, 45 ; et deux dispositifs d'accouplement 47, 48, devant et derrière l'aimant permanent 46 et les deux bobines 44, 45.
(JA) 内視鏡用リニアアクチュエータ40は、磁性体から形成された移動枠42と、移動枠42が進退自在に内部に設けられ、非磁性体から形成された固定枠43と、固定枠43の外表面に巻回形成され、長手軸方向に並設された2つのコイル44,45と、2つのコイル44,45に重畳するように積層配置された永久磁石46と、永久磁石46および2つのコイル44,45の前後に配設された2つのヨーク47,48と、を具備する。
