In-situ Runout Idientification in Active Magnetic Bearing System by Extended Influence Coefficient Method

확장된 영향계수법을 이용한 능동자기베어링의 운전상황에서 측정체 진원도 오차 규명

In this study, an efficient, yet easy to use, in-situ runout identification scheme by using extended influence coefficient method is presented for active magnetic bearing(AMB) systems. It is shown experimentally that the proposed scheme successfully identifies and eliminates the troublesome runout of the well balanced AMB system in the laboratory so that a high precision spindle system can be achieved, while it is in operation.
