Energy storage flywheel systems are mechanical devices that typically utilize an electrical machine (motor/generator unit) to convert electrical energy in mechanical energy and vice versa. Energy is stored in a fast-rotating mass known as the flywheel rotor. The rotor is subject to high centripetal forces requiring careful design, analysis, and fabrication to
Ke = 753Nm. Therefore, mass moment of inertia as per eq.5 is. I = 753 / 0.02 (2π*1000/60)2. I = 3.43 Kg.m2. Hence, the flywheel sizing/design calculation for the above example shows that the required mass moment of inertia for this application should be = 3.43 Kg.m2. Gopinath K.
