Flywheel energy storage
The usable energy will be 8 / 9 ths of the actual energy at maximum speed, E max, for ω min = 1 / 3 ω max, and ¾ E max for ω min = 1 / 2 ω max. Given the size and cost of the electric machine is roughly proportional to torque, choosing ω min = 1 / 3 ω max would lead to an electric machine that is 50% larger than if ω min = 1 / 2 ω max …
