FAQ: How do I calculate the inertia of a servodriven system?
Sep 29, 2016 · J D = inertia of drive (ball screw, belt, rack & pinion) J E = inertia of external (moved) load. J C = inertia of coupling. Manufacturers typically provide the inertia value (or a simple equation to calculate the inertia value) of drive systems, such as ball screws. But if the inertia value isn’t provided, it must be calculated manually.
