Abstract
본 발명은 자기물질의 전기자(7)가 내부의 2개의 안정위치사이에서 축방향 이동가능하게 되어 있는 자기물질로 된 하우징(1)을 갖는 쌍안정성 자기작동기에 관한 것으로서, 이 하우징의 말단은 극편(4)(5)에 의해 폐쇄되고, 상기 전기자는 상기 극편 중 하나 또는 양쪽을 통해 축방향으로 미끄럼가능하게 안내되는 푸쉬로드(push rod) (9)를 구비하며, 상기 하우징은 대체로 일 극편으로부터 나머지 극편까지 상기 하우징의 내측으로 연장되어 있는 자기 코일(3)을 수용하고, 상기 전기자의 축방향 치수는 상기 전기자가 그것의 안정위치들 중 어느 한 위치에 있을때 상기 전기자의 말단은 상기 극핀 중 대응하는 것과 밀접한 위치에서 그것과 접촉하고 상기 전기자의 다른 말단과 상기 극편 중 다른 것 사이에는 축방향 간극(14)이 존재할 수 있도록 설정되며, 상기 코일의 활성화없이도 전기자를 자기적으로 보유하여 2개의 안정위치중 어느 한 위치에 위치시킬수 있도록 상기 전기자와 극편들에 작용하는 영구자석(12)(13)이 제공되고, 적절히 배향된 전류에 의해서 상기 코일을 활성화시키면 상기 간극과 인접해 있는 상기 전기자의 말단에서 자속 밀도가 증가하고 상기 전기자의 타단에서는 자속이 감소하도록 됨으로써, 상기 전기자가 다른 안정위치로 이동되어 상기 코일의 비활성화후 안정하게 유지될 수 있게 된다.The present invention relates to a bistable magnetic actuator having a housing (1) made of magnetic material in which the armature (7) of the magnetic material is axially movable between two stable positions therein, the end of which is the pole piece. (4) (5) closed and the armature has a push rod 9 slidably axially guided through one or both of the pole pieces, the housing being generally from one pole piece A magnetic coil 3 extending inwardly of the housing to the other pole piece, the axial dimension of the armature being the end of the armature corresponding to one of the pole pins when the armature is in one of its stable positions In contact with it at a position close to that of the arm and set such that there is an axial gap 14 between the other end of the armature and the other of the pole pieces, Permanent magnets 12 and 13 acting on the armature and the pole pieces are provided to magnetically retain the armature without activating the coil and to be positioned at any one of the two stable positions, and by means of a properly oriented current Activating the coil increases the magnetic flux density at the end of the armature adjacent to the gap and decreases the magnetic flux at the other end of the armature, whereby the armature can be moved to another stable position to remain stable after deactivation of the coil. Will be.
