This paper investigates the possibility to control the radial displacements of the shaft of an electrical machine equipped with a multi-three-phase winding arrangement with the aim of reducing the related vibrations. A comprehensive dynamic modeling of all subsystems is first presented. Each part of the system is described in order to comprehend the developed model. Then the dynamic simulation of the full system is performed considering different rotating speeds. The results show the effectiveness of the proposed control strategy, highlighting the possibility of safely operating the motor around the critical speed and presenting the requirement for a control improvement at high-speed values.
