Inertia Calculators

Please note: Before you start, you need to know the dimensions of your parts, the material, and the speed they are running.

Please fill in the answers to the following questions to calculate your system inertia. Start at your last rotating piece and work back to the clutch or brake. The inertia of all the components running at the same rpm in your machine should be added together before moving back to the previous speed differential towards the clutch or brake.

RPM

What is the RPM for all of the component parts in this section of the machine?
(Please note:parts could be whole parts, such as shafts or solid pulleys, or they could be components such as large pulley broken up into its component parts)
