In this paper, an efficient, yet easy-to-use, in-situ runout identification scheme, based on the 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 a well-balanced AMB system in the laboratory, so that a high-precision spindle system can be achieved, while it is in operation.
