Flywheel Systems for Utility Scale Energy Storage
The flywheel was brought to full speed (9,000 rotations per minute [rpm]) which is equivalent to the maximum energy storage capacity of 32kWh for the M32 flywheel. Using custom controls software, the speed was increased to 9,653 rpm which is a 15% overstress condition to the flywheel rotor.
