Use this equation and calculator to determine the Inertia of a direct drive system. The calculations assume there is no linkages and the all friction is exclusively within the load. 


Direct Drive System

Equation:   

           

Where:

Jt =   System Inertia, lb-in.-sec2
Jl =   Load Inertia, lb-in.-sec2
Jm =  Drive Motor Inertia, lb-in.-sec2
