Construction, Modeling and Evaluation of a Low Loss Motor
... Equation (2.1) shows that the energy stored in a flywheel is proportional to the polar mass moment of inertia (i.e. the mass, if equal shapes for different materials are assumed) and to the square of the angular speed. Thus, stored energy can be increased either by choosing a material with higher ma ...
