When speaking about other energy storage devices, flywheels can be viable alternatives due to the low degradation process during the entire operating life, and its numerous energy discharge rates. In this paper, the problem of the flywheel shape, present in the KERS system, is approached analytically. The analysis was performed on three series of rotors and the results were validated using a CAD program. The linear relationship between the mass of the flywheel mass and its rotation axis was emphasized by Pappus-Guldin theorem. Based on the results it was shown that the value of kinetic energy is higher when the mass of the flywheel is concentrated closer to the axis of rotation.
