This paper describes the suppression of vibration which is generated on rotating machinery with an overhung rotor. We propose a rotor-shaft system supported by rubber springs which are installed on the pole surfaces of the electromagnets. This is a hybrid type equipment in which a bearing housing is supported elastically by rubber springs and controlled actively by electromagnetic actuators. These actuators are controlled by displacement sensors at the pedestal and/or the roller and can apply an electromagnetic force which suppresses any vibration of the roller. In the analysis, we calculate the controller gains which minimized the amplitude of vibration at the roller. In the experiment, the results correspond to the analytical results, and we confirm that the hybrid type equipment is a highly effective method for vibration suppression.
