Abstract

This elaboration presents a comprehensive approach to identify the parameters of the novel six-pole axial active magnetic bearing actuator with current-driven electromagnets. The developed actuator is devoted to compensate for the tilt motion of disc-type machines by suppressing lateral vibrations with three actively controlled force vectors. This research emphasizes the interdisciplinary identification of magnetic bearing parameters using various measurement methods. In particular, the impact of inaccuracy inspired by the imperfections of the real prototype was investigated. Furthermore, a chaotic motion of the disc was observed in the plane perpendicular to its levitation direction. The coil parameters were measured with a precise indication of the differences. The thermal reliability of the bearing was tested with an increase in current and weight load up to twice the nominal operational temperature. The study extends the crucial aspect of measuring and calculating the electromagnetic force through four methods with decent convergence between them. In general, the proposed mechatronic actuator is capable of increasing the stability range of rigid or flexible rotors and is characterized by favourable dynamic properties, which was demonstrated in the shaker test with external harmonic excitation. A complete description of the actuator with uncertainties in the parameters was obtained by accessible in situ identification. © 2023
