How does a flywheel energy storage system work?
Flywheel energy storage uses electric motors to drive the flywheel to rotate at a high speed so that the electrical power is transformed into mechanical power and stored, and when necessary, flywheels drive generators to generate power. The flywheel system operates in the high vacuum environment.
What is the function of a flywheel?
The basic function of the flywheel is to convert the mechanical energy for the end-use application, which is electrical energy. For this conversion, an electromechanical machine is required which could be a motor/generator set. Generator and motor: When the kinetic energy is being stored, the motor is used to drive the flywheel.
Are flywheel energy storage systems feasible?

What is the operational mechanism of a flywheel?
The operational mechanism of a flywheel has two states: energy storage and energy release. Energy is stored in a flywheel when torque is applied to it. The torque increases the rotational speed of the flywheel; as a result, energy is stored. Conversely, the energy is released in the form of torque to the connected mechanical device .
