Technical FAQs 4

How does a flywheel energy storage system work?

Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to produce electricity.

How does a flywheel generator work?

The operating principle of a flywheel generator is simple and yet strong. When the system is supplied with energy, the flywheel speeds up, storing the energy as kinetic motion. When there is a demand for power, the stored energy is converted back into electrical energy, which provides a smooth supply of power.

Are flywheel generators a game-changer?

Flywheel technology is increasingly emerging as a game-changer in current energy solutions. With industries moving towards efficient and sustainable energy patterns, flywheel generators present a cleaner option that reduces energy loss while maximizing up-time.

What industries use flywheel generators?

Flywheel generators are all-around and can be used across multiple industries, including: Telecom Industry is to provide an uninterrupted power supply. Marine Industry for stable and dependable energy on boats. Off-Highway Machinery, where reliability and rapid energy discharge are essential.
