Investigation of resonance characteristics of a idle inflexible rotor under conditions of axial electromagnetic suspension at a plane motion

Service conditions of workable in OKBM turbomachine with a vertical shaft are such that active electromagnetic bearings have to be used there. One of main problems of a control system electromagnetic a bearing is to ensure of stability of the system (rotor - control system). In given work conditions of occurrence and limiting of fluctuations of a rotor (a pendulum-type) in a nonlinear formulation are analysed. At the given stage of studies the problem is limited by frameworks of idle, inflexible rotor assuming absence of energy dissipation.
