Title (EN) ELECTRIC LINEAR ACTUATOR
(FR) ACTIONNEUR LINÉAIRE ÉLECTRIQUE
(JA) 電動式直動アクチュエータ
Abstract:
(EN) Provided is an electric linear actuator such that a reduction in installation space and a reduction in cost can be achieved. This electric linear actuator comprises an electric motor that is an axial gap motor which is provided with a stator (7) and a rotor which are arranged so that the direction of magnetic poles generating interlinkage magnetic flux contributing to torque becomes parallel to the rotation axis (L1) of the electric motor. Furthermore, a linear mechanism and the electric motor are arranged adjacent to each other on the same axis, which is the axis of the rotary input/output shaft of the linear mechanism. First and second coil terminals (53), (54) have extension portions (53a), (54b) extending towards the outer diameter in the radial direction of the rotation axis (L1), the extension portions (53a), (54a) being electrically connected to a control device through a wiring mechanism.
(FR) La présente invention concerne un actionneur linéaire électrique permettant d’obtenir une réduction de l’espace d’installation et une réduction du coût. Cet actionneur linéaire électrique comprend un moteur électrique qui est un moteur à entrefer axial pourvu d’un stator (7) et d’un rotor qui sont agencés de sorte que la direction des pôles magnétiques générant un flux magnétique d’interliaison contribuant au couple devienne parallèle à l’axe de rotation (L1) du moteur électrique. En outre, un mécanisme linéaire et le moteur électrique sont agencés de façon mutuellement adjacente sur le même axe, qui est l’axe de l’arbre d’entrée/de sortie rotatif du mécanisme linéaire. Des première et deuxième bornes de bobine (53), (54) comportent des parties d’extension (53a), (54b) s’étendant vers le diamètre externe dans la direction radiale de l’axe de rotation (L1), les parties d’extension (53a), (54a) étant électriquement connectées à un dispositif de commande par l’intermédiaire d’un mécanisme de câblage.
(JA) 搭載スペースの低減およびコスト低減を図ることができる電動式直動アクチュエータを提供する。この電動式直動アクチュエータの電動モータは、トルクに寄与する鎖交磁束を発生する磁極の向きが、電動モータにおける回転軸(L1)と平行になるように配置された固定子(7)および回転子を備えるアキシアルギャップモータである。さらに直動機構と電動モータとが、直動機構の回転入出力軸の軸心となる同一の軸心上に並んで配置されている。第1,第2コイル端子(53),(54)は、いずれも回転軸(L1)の径方向外径側に延長された延長部分(53a),(54a)を有し、延長部分(53a),(54a)は配線機構を介して制御装置に電気的に接続されている。
