Energy Storage Flywheel Rotors—Mechanical Design
Energy storage flywheel systems are mechanical devices that typically utilize an electrical machine (motor/generator unit) to convert electrical energy in mechanical energy and vice versa. Energy is stored in a fast-rotating mass known as the flywheel rotor. The rotor is subject to high centripetal forces requiring careful design, analysis, and fabrication to …

How the Flywheel Works. The flywheel energy storage system works like a dynamic battery that stores energy by spinning a mass around an axis. Electrical input spins the flywheel hub up to a high speed and a standby charge keeps the unit spinning until its called upon to release . its energy. The energy is proportional to its mass and speed …

DIY Flywheel Energy Storage on a small scale? : r/AskEngineers
Generator flywheel and diesel were on one axis with a coupling towards the diesel. The flywheel was constructed as an engine around that axis, so the stator is the axis at 1500 rpm and the flywheel turns around at max. 4400 rpm. If energy needs to be provided, the outer rotor is slowed down by a brake in that axis, so the energy is transferred
