Investigation of the energy saving capability of a Variable Inertia Magneto-Rheological (MR) Flywheel

Abstract— This research focuses on a theoretical and experimental analysis of a variable inertia magneto rheological flywheel (VIMRF). The objectives of the present study were to design and fabricate the prototype of a VIMRF and perform characteristics of energy saving capability of it. The moment of inertia has been calculated under different angular speeds and excitation currents. The prototype was designed and manufactured to verify the effectiveness of the proposed VIMRF. Simulations are primarily done to find variable characteristics of the moment of inertia of the VIMRF under certain conditions. The primary simulation shows that the moment of inertia of the VIMRF can semi-actively be tuned
