I have a dynamometer to determine HP and Tq of cars and im trying to setup my software and i need the inertia of my rollers to determine Tq but i have a big flywheel that will turn 1,580 revolution per each roller revolution so its very difficult to determine inertia by calculating the mass of the rollers + mass of the flywheel + gearing multiplier etc...(adsbygoogle = window.adsbygoogle || []).push({});

Someone told me that i should be able to determine inertia by turning my roller to 2000rpm and calculate the time it decelerate from 1500rpm - 500rpm

Do anybody can give me this formula or the right way to determine inertia by doing that

Thanks
