## Main Question or Discussion Point

Hello guys,

I am working on designing a flywheel to couple to a generator however i have a small problem and i have low knowledge in flywheels

I have a pinion rotating at w = 14.13 rad/sec and torque Tpinion = F*Rpinion = Mass of inertia *alpha pinion

All is known I can find Tpinion euqal around 0.0006 N.m (Rp = 2cm , alpha pinion = 88 rad/s^2 , m = 700g) Now the question :

After the pinion there is a gearbox of 1/20 coupled to a flywheel coupled to a generator

My generator gives 10 w with minimum RPM of 2500

My system gives me around 2700 RPM

So i need a certain amount of Torque = 0.035 N.m to get this power output.

Does the free wheel add torque ? and what the equation coupled with the gearbox be?

thank you for your time and I appreciate every help

Edit: I was considering the angular acceleration for the Flywheel to be alpha pinion *20 due to gearbox is it correct as well?
