## Main Question or Discussion Point

Hello! I've got a problem that I haven't the faintest clue how to go about. I have a flywheel, spinning on a motor's shaft. I want to be able to calculate the time it will take the flywheel to spin up to the motor's max RPM, based off of the variables:

Motor's RPM

Motor's Toque

Flywheel's mass

Flywheel's shape (Solid disk, disk with outer ring, etc.)

Flywheel's diameter.

I have a fixed motor, with enough amperage that it will always be able to draw as much as it needs (from stall.) I'm varying the flywheel's mass and shape to find a good balance of low spin-up time to high stored energy. The flywheels are used to propel items, if it matters.

Thanks!
