Abstract

This paper proposes a new method to identify concurrently unbalance and sensor runout on a rigid rotor supported by magnetic bearings. At first, the paper investigates the effectiveness of the incremental least square online method applying to identify unbalance and sensor runout by a numerical simulation. Secondly, the paper also presents results of the numerical simulation on identification accuracy at various speeds and effects of the rotor model error. Inconclusion, we are confirming that the new identification method is effective by comparing the simulation results on the various speed and influence of the motor model errors.
