Abstract: 기존 회전기의 자기 베어링 장치는 반경방향의 위치를 제어하는 반경방향(radial) 자기 베어링과 축방향의 위치를 제어하는 축방향(axial) 자기 베어링으로 구성되어 있다. 기존 회전기의 자기 베어링 장치는 반경방향 자기 베어링만 사용할 경우 반경 방향의 힘은 크나 안정된 축방향 힘이 적으므로 축방향 제어를 위한 축방향 자기 베어링이 추가로 필요하게 되어 총 3개의 베어링이 필요하였다. 본 발명의 반경방향 자기 베어링은 고정자와 회전자의 자극 중간에 각각 비자성체를 삽입함으로써, 안정되고 기존의 반경방향 자기 베어링 보다 큰 축방향 힘을 얻을 수 있다. 따라서 기존의 축방향에 대한 부수적인 축방향 자기 베어링 없이 반경방향 자기 베어링만으로 회전기의 자기 베어링 장치를 구성할 수 있다.

Therefore, along with reduction in capacity of controller, high-speed operation and highly efficient operation become possible, small size and lightweight can be obtained, and maintenance can be simpler.
