I am a little confused and need your help. I want to lift a robotic arm that would have to its end a 2kg load (20cm away from lead screw attachment point).
My initial calculations using T= leadforce/2pi suggest that this lead screw and stepper motor system is going to be sufficient. My projects power supply is a 12V dc. The graphs plot on the data sheet for the force vs speed are with 24Vdc.
If I connect it with a 12v battery on the H-bridge controller would I get half of that output torque? Any thoughts or suggestions?
Really appreciate your guidance.\
Thank you in advance
