How does a flywheel work?

The flywheel works based on Newton's first law of motion applied to rotating systems, wherein the flywheel keeps rotating even after removal of the source transferring rotational energy. This rotation of the flywheel after the removal of the source is then utilized to harness energy when required by the system interconnected to it.

How a flywheel is conditioned?

The power from the source is conditioned accordingly based on the motor rating using a power-conditioning unit (PCU). In this stage, electrical energy is converted to mechanical energy. The motor generates higher torque, which drives the flywheel at a higher rota-tional speed.

Why does a flywheel store energy kinetically?

The motor generates higher torque, which drives the flywheel at a higher rota-tional speed. Hence, the flywheel stores the energy kinetically, which is proportional to the square of its rotational speed and its moment of inertia (M.I). This energy can be used to operate an electric generator.

How do you drive a flywheel?

To drive the flywheel, a BLDC motor and a separately excited alternator are used. The excitation can be provided through another converter from the PV source or through suitable self-excitation methods with suitable converters for real-life implementation.
