This study aims to analyze the effect of electrical voltage and flywheel mass on the kinetic energy produced by the starter motor, as well as to evaluate the geometric shape of the flywheel. The kinetic energy in the flywheel is influenced by the moment of inertia and angular velocity produced by the starter motor. The study was conducted exprerimentally using a quatitative approach, with variations in voltage (11V-14V) and flywheel mass (0.9-1.2 kg), and analyzed using a Two-Way ANOVA Faktorial test. The results show that both voltage and flywheel mass significantly affect kinetic energy, with increased voltage linearly increasing RPM and energy, and a larger mass increasing the moment of inertia. The interaction between the two is synergistic, with the combination of 1.2 kg and 14V voltage yielding the highest energy (4.0 Joules), and an R-squared value of 97.65 % indicating the model is highly accurate. These findings support the development of efficient mechanical energi storage system and optimal flywheel design.

Flywheel is an important element in the motor starter system due to its ability to store relase kinetic energy during the rotation process. This study aims to evaluate the effect of rotation speed variation and flywheel geometry shape on the kinetic energy produced, assuming the flywheel mass is fixed. The analysis is conducted through theoretical approach and numerical simulation using the rotational kinetic energy equation, with I as the moment of inertia that depends on the geometry shape,and as the angular velocity and shape of  the flywheel. The results show that the geometry shape greatly affects the moment of inertia, and at the same angular velocity, the flywheel with larger moment of inertia is able to store more kinetic energy. The conclusion of this study provides recommendations in the selection of the optimal flywheel design to improve the efficiency of the motor starter system.
