The paper is concerned with the problem of active stabilisation of a rotating slender shaft equipped with electromagnetic actuators. The actuators exert an attractive force on the shaft, which strongly affects the dynamical behaviour of the system. The aim of the paper is to show that the application of electromagnets may considerably enlarge the critical rotation speed at which the shaft exhibits self-excited vibration. This undesired effect can be shifted towards larger operational rotation speeds, which is confirmed in the following study for selected structural and material parameters of the entire system.
