Title (EN) PIEZO ACTUATOR HAVING AN ELECTRODE STRUCTURE FOR A TORSIONAL VIBRATION MODE, AND ROTATION-TYPE ULTRASONIC MOTOR INCLUDING SAME
(FR) ACTIONNEUR PIÉZOÉLECTRIQUE À STRUCTURE D'ÉLECTRODES POUR MODE DE VIBRATION DE TORSION ET MOTEUR À ULTRASONS DU TYPE ROTATIF LE COMPRENANT
(KO) 비틀림진동모드가 가능한 전극구조를 갖는 압전진동체 및 이를 포함하는 회전형 초음파 모터
Abstract: front page image
(EN)The present invention relates to a piezo actuator having an electrode structure for a torsional vibration mode, and to a rotation-type ultrasonic motor containing the same. In the piezo actuator having the electrode structure, electrodes may have different lengths from the center point of the piezo actuator in order to form an electrode structure having a pinwheel shape by means of which a torsional vibration mode is enabled. Thus, since the electrodes of the piezo actuator for generating torsional vibrations has a simple pinwheel wing structure, a rotor coupled along a groove formed in the side surface of the piezo actuator may be rotated using the torsional directional vibrations due to the electrode structure.
(FR)La présente invention porte sur un actionneur piézoélectrique, ayant une structure d'électrodes pour un mode de vibration de torsion, et sur un moteur à ultrasons du type rotatif le contenant. Dans l'actionneur piézoélectrique ayant la structure d'électrodes, des électrodes peuvent avoir des longueurs différentes, à partir du point central de l'actionneur piézoélectrique, de manière à former une structure d'électrodes en forme de moulinet au moyen de laquelle un mode de vibration de torsion est obtenu. Ainsi, étant donné que les électrodes de l'actionneur piézoélectrique servant à générer des vibrations de torsion possèdent une structure en ailes de moulinet simple, un rotor couplé le long d'une gorge formée dans la surface latérale de l'actionneur piézoélectrique peut être amené à tourner à l'aide des vibrations de torsion dues à la structure d'électrodes.
(KO)본 발명은 압전진동체의 중심점으로부터 전극 길이가 다르게 형성 되도록 하여, 비틀림진동모드가 가능한 바람개비 형태의 전극구조를 갖는 압전진동체 및 이를 포함하는 회전형 초음파 모터에 관한 것으로, 비틀림진동을 발생하는 압전진동체 전극구조로서 바람개비 날개 형태를 갖는 단순구조를 제공하고, 이와 같은 전극구조에서 얻어지는 비틀림방향 진동을 이용함으로써, 상기 압전진동체의 옆면의 홈을 따라 체결된 회전자가 회전할 수 있는 회전형 초음파 모터를 제공하는 발명에 관한 것이다.
