- TL;DR Summary
- 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 -

The formula is: Jt = Jscrew + Jload.

This calculation relies on the fact that the load moves

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:

__.__**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

__a power screw - see the attached schema - in Scheme # 2.__**on**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?**
