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 |
