What does a flywheel do and how does it work?
In: Engineering
A flywheel is a heavy wheel attached to a shaft to help maintain momentum. Basically the more weight you can get moving (and the further that weight is from the axis) the harder it is to get it to stop spinning.
This is good in applications where you want smooth and continuous rotation, so motors and engines. You’ll see them on generators, cars, conveyors, etc.
