Abstract
The flywheel device includes a sealed housing section; a rotor located in the sealed housing section where the rotor is held in a vertical position by a magnetic system; a controller coupled to the magnetic system; and a braking annular ring mounted to the sealed housing section below the rotor, where the rotor contacts the braking annular ring when the rotor is lowered or otherwise dropped from the vertical position. The controller performs operations to provide control signals to provide first power to the magnetic system to hold the rotor in the vertical position and provide second control signals to provide second power to the magnetic system to lower the rotor.
