Different types of flywheel energy storage systems have been studied in this work. A flywheel energy storage system can be thought of as a mechanical battery that stores energy kinetic energy. The objective is to maximize the energy density of the system. However, the parameters that we change to increase the energy stored in the system might cause the system to collapse if we exceed the maximum allowable stress (the yield strength of the flywheel’s rotor material), hence, a stress analysis study for flywheel rotors is essential in order for us to find out if a rotor is capable of withstanding the given conditions in order to avoid failure. The challenge is to reduce the stress on the rotor in order for us to be able to have a greater angular speed. The results show that having a very large or very low number of spokes will cause failure to occur faster. A large number of spokes caused the failure to occur on the spokes, whereas a small number of spokes caused failure to occur on the rim of the rotor.
