The aim of this thesis is to design a test bench to study the dynamic behaviour of a rotor with passive magnetic bearings characterized by the minimisation of the energy dissipated due to friction. This rotor is connected to an actuation system consisting of a magnetic clutch and an electric motor in order to simulate its behaviour as a kinetic energy accumulator. The first part of the thesis describes the optimisation of the original rotor design, the layout of the support structure for measuring displacements and angular velocity, the project of the actuation system and the electrical wiring to control it. The second part concerns experimental analysis and consists of the collection and post-processing of displacement and speed data of another magnetic rotor in order to carry out preventive tests before studying the rotor designed in this thesis.
