A flywheel energy storage motor is a mechanical device that stores energy through rotational motion. It works by spinning a rotor (flywheel) at very high speeds, which allows it to store energy as rotational energy. When excess electricity is available, it accelerates the flywheel, and when energy is needed, the stored energy can be quickly converted back to electricity using an electric motor/generator24. This technology is efficient for managing power supply and demand, providing backup power, and supporting renewable energy sources5. [pdf]
