Abstract
The flywheel is a classic mechanical device that is often used to enhance the rotational motion of engines. Electrical machines often face fluctuations in speed that hamper speed stability and cause extra power consumption. Recently, a few publications have analyzed the impact of the flywheel to reduce fluctuation and energy consumption in electric motors. This study proposes the use of a flywheel with a changeable moment of inertia, which can be manipulated to boost both speed stability and energy efficiency. The objective is to improve the speed stability of industrial motors in the presence of the loading effect. This study introduces a magneto-rheological variable inertia flywheel (MRVIF) to control rotational speed and reduce power usage. The purpose of analytical development is to assess the influence of rotational speed and excitation current on the MR damper's moment of inertia for control purposes. The investigation focuses on the analysis of power usage and stability across different power inputs and rotating speeds. The effectiveness of the suggested MRVIF was evaluated via the development of a prototype. Experiments were undertaken to validate the effectiveness and stability of the system. The findings illustrate the potential use of MRVIF in reducing energy consumption and enhancing speed stability
