Claims (3)
- 코일이 권선되는 고정자 코어와, 상기 고정자 코어의 상부에 소정 간극으로 유지되고 저면에 영구자석이 부착되는 회전자 코어를 포함하는 액츄에이터에 있어서,
상기 회전자 코어는 상면에 스토퍼 마그넷이 부착되고,
상기 액츄에이터는 상기 스토퍼 마그넷의 상부에 배치되어 스토퍼 코일이 권선되는 스토퍼 코어와; 상기 스토퍼 코어를 상기 회전자 코어의 상면으로 가압하는 탄성가압수단을 더 포함하며,
상기 회전자 코어의 정지 시, 상기 스토퍼 코일에는 전류 인가가 해제되어 상기 스토퍼 코어가 상기 탄성가압수단의 가압으로 인해 이동하여 상기 회전자 코어 상면의 스토퍼 마그넷에 부착되고,
상기 회전자 코어의 회전 구동시, 상기 스토퍼 코일에는 전류가 인가되어 상기 스토퍼 코어가 상기 탄성가압수단의 가압력을 극복하고 상기 회전자 코어 상면의 스토퍼 마그넷으로부터 이탈되는 것을 특징으로 하는 액츄에이터. - 제1항에 있어서,
상기 스토퍼 마그넷은 고리 모양의 원판으로서 N극 원판과 S극 원판이 적층 구비된 것임을 특징으로 하는 액츄에이터. - 제1항 또는 제2항에 있어서,
상기 스토퍼 코어는 상기 스토퍼 마그넷에 대응되는 저면이 원판 형상인 것을 특징으로 하는 액츄에이터.
