- calculation of lead screw moment inertia with weight
In order to choose a DC motor according to the article titled: APPYING MOTORS IN LINEAR MOTION APPLICATION by PITTMAN -
step 4 : "determine the total reflected inertia (Jt) back from the load to lead screw shaft " .
The formula is: Jt = Jscrew + Jload.
This calculation relies on the fact that the load moves on a power screw - see the attached schema - in Scheme # 2.
My system is different and the number in the schema is # 1
The load is located at distance L, on both sides of the center of the screw.
My request: How do you calculate the load inertia in this situation?
