During energy storage, electrical energy is transformed by the power converter to drive the motor, which in turn drives the flywheel to accelerate and store energy in the form of kinetic energy in the high-speed rotating flywheel [72]. The motor then maintains a
Energy storage in flywheels. A flywheel stores energy in a rotating mass. Depending on the inertia and speed of the rotating mass, a given amount of kinetic energy is stored as rotational energy. The flywheel is placed inside a vacuum containment to eliminate friction-loss from the air and suspended by bearings for a stabile operation.
Moment of inertia depends on the flywheel mass and geometry [1] as follows: (2) I = ∫ r 2 d m where r is the distance of each differential mass element dm to the spinning axis.The bi-directional power converter transforms electrical energy at the machine frequency ...
