What are some tips for designing a consistent and fast flywheel? I know it will eventually come down to copious amounts of iterative testing, but I want to just get a general idea of where to start.
Some questions, some of them probably need testing with physical foam disks to be answered:
Flywheel material? More ridged traction wheels or more compliant flex wheels?
Does more disc contact with the flywheel matter or mostly just compression with the flywheel?
How much weight would be a good balance between spin up time and inertia for 1 motor? 2 motors?
