Abstract
자기 베어링 장치가 개시되어 있다. 이 자기 베어링 장치는 샤프트를 비접촉으로 축방향 지지하는 스러스트 자기 베어링과 반경 방향으로 지지하는 레이디얼 자기 베어링으로 이루어져 있고, 특히 회전자의 일측에 위치한 스러스트 자기 베어링이 복수개 구비되어 있고, 이 스러스트 자기 베어링에 연하여 복수개의 갭센서가 구비되어 상기 각각의 스러스트 자기 베어링과 갭센서가 독립적으로 작동된다. 따라서, 샤프트가 고속 회전시 그 회전력과 진동에 의하여 발생되는 휨을 감지하여 각각의 스러스트 자기 베어링에 인가 되는 전류 세기를 조절하여 휨을 방지할 수 있어서, 상기 샤프트가 안정적으로 회전 가능하게 하고 축방향의 지지를 통하여 산업용 로봇등의 5축 제어를 요하는 곳에도 이용될 수 있다.A magnetic bearing device is disclosed. This magnetic bearing device consists of a thrust magnetic bearing for supporting the shaft axially in a non-contact manner and a radial magnetic bearing for supporting in a radial direction. In particular, the thrust magnetic bearing is provided with a plurality of thrust magnetic bearings located on one side of the rotor. In addition, a plurality of gap sensors are provided so that each of the thrust magnetic bearings and the gap sensors is operated independently. Therefore, by detecting the bending caused by the rotational force and vibration when the shaft rotates at a high speed, it is possible to prevent the bending by adjusting the current strength applied to each thrust magnetic bearing, so that the shaft can be rotated stably and the axial support It can also be used in places requiring 5-axis control, such as industrial robots.
