Description
Claims (4)
- 양면에 서로 다른 전극이 형성되도록 처리된 돔 형상의 압전 세라믹;상기 압전 세라믹의 변위에 연동되도록 상기 압전 세라믹의 일면에 고정되는 진동축; 및상기 진동축에 접촉되어 있으면서 상기 진동축과의 마찰에 의해 선형으로 구동되는 이동체;를 포함하여 이루어지는 향상된 변위를 제공하는 선형 압전 모터.
- 제1항에 있어서,상기 압전 세라믹을 지지하는 동시에 상기 압전 세라믹의 가장자리 방향으로의 변위를 소정의 크기로 구속하기 위한 브라켓을 더 포함하는 향상된 변위를 제공하는 선형 압전 모터.
- 제1항에 있어서,상기 이동체와 진동축과의 접촉부위에는 소정의 가압부재를 통해 일정한 마찰력이 유지되는 것을 특징으로 하는 향상된 변위를 제공하는 선형 압전 모터.
- 제1항 내지 제3항 중 어느 일 항에 있어서, 상기 이동체는상기 진동축이 이동할 때 상기 이동체의 관성력이 상기 진동축과의 마찰력보 다 작은 경우에 상기 진동축의 이동방향에 따라 이동하는 것을 특징으로 하는 향상된 변위를 제공하는 선형 압전 모터.
