Abstract: Disclosed is a contactless mass measuring device for measuring current values consumed when the displacement of a levitation member is corrected depending on the load applied in a magnetic levitated contactless state and converting the current values to mass. The present invention comprises: the levitation member having a cross-shaped cross section; a pair of permanent magnets of which one is installed on the top of a vertical part and the other is separated therefrom so that the levitation member can be levitated; horizontal electromagnets for radially supplying suction force from the axial center of the vertical part to guide the levitation member; an axis sensor for detecting whether or not the center of the vertical part matches with the center of the horizontal electromagnets; and ring-shaped vertical electromagnets for supplying the suction force in the vertical direction of a horizontal part to control the vertical position of the levitation member; a height sensor for detecting whether or not the horizontal part is positioned at the center between the vertical electromagnets; a control part connected to the height sensor to output the current to the vertical electromagnets so that the horizontal part can be returned to the original position when not positioned at the center between the vertical electromagnets; and a calculation part for measuring the current values outputted from the control part through a current sensor and converting the current values to the mass of a sample.

Abstract: 회전축의 크기가 증가되더라도, 베어링코어의 크기가 과도하게 증가되지 않게한 자기베어링에 대한 것이다. 자기베어링에 포함된 베어링코어는, 회전축을 기준으로 원형 배열된 복수의 단위 코어부들을 포함한다. 이에 따라, 자기베어링 제작의 독립성이 보장될 뿐만 아니라, 종래의 자기베어링에서 야기되는 재료상의 한계점을 극복할 수 있다.
