Calculating Reflected Inertia for Linear Systems
This effectively is the linear load inertia converted to rotary load inertia that the motor shaft sees. We know that our load weighs 200 pounds and that we have a 5 pitch screw. Plug and chug again: J load = (200/5 2)*0.0253 = 0.2 lb-in2. The total reflected inertia to the motor shaft is the sum of the two inertias:
