Well, contractor made a mistake in given parameters. The duration of spinning flywheel is not 10 minutes, but 10 seconds. Now the mass and energy values are not so crazy.
Thank you all for your help!

Thank you both!
I have to use flywheel, because its "contractor's" request. It is a part of the bigger project. However.
The idea is to spin up the flywheel to f.e. 1500 rpm, let it produce energy to empower the generator for like 10 minutes and at some point (where as you mentioned the...

Hi guys! I have a real life physical problem. I need to calculate the mass and diameter of a flywheel made of steel to run generator with parameters: 123 kVA - 98 kWe; Frequency 50 Hz, 400 V, Class F M8 - 674 nM.
The better question is, how much (kinetic) energy do I have to input into the...
