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.
