Abstract

영구자석을 구비하여 별도의 편향 전류 없이도 회전체를 부양시키면서 영구자석의 착자가 용이한 자기베어링 구조가 개시된다. 본 발명에 따른 자기베어링 구조는 회전축의 측면에 위치하여 착자가 상기 회전축의 회전축 방향과 평행하도록 이루어지는 고리형의 영구자석, 상기 영구자석의 일측에 구비된 코일, 그리고 상기 코일의 외측에 구비되어 자기장 경로의 형성에 관여하는 도체부를 포함한다. 이와 같은 구성에 의하면, 자기베어링에 구비된 코일에 별도의 편향 전류를 공급해 주지 않아도 영구자석에 의한 자기장에 의하여 회전체가 부양되면서, 상기 영구자석의 착자 방향이 회전축의 축방향과 평행하게 이루어지는바 착자가 용이하여 자기베어링의 생산성이 증대된다.
