    Torque Margin for a Lead Screw

    Ok there's some great advice in there, thank you. I'm starting to think maybe just using a margin on the leadscrew force is enough, and then determining torque from there based on geometry, friction, etc. This will be a brushless motor with plenty of feedback control, but I can also see if...

    Torque Margin for a Lead Screw

    Thanks drawoh. I think this really boils down to a question of conventions and the appropriately way to determine torque margin. My ultimate purpose is to select an actuator (specifically the output planetary gearhead, since speed and power are not important here, only torque). I need the...

    Torque Margin for a Lead Screw

    Hi and thanks for taking a look at my question. I'm designing a lead screw mechanism and I'm seeking to show that I have sufficient torque margin (I know this is vague, but that's the crux of my question as you will soon see). I'm using splines on the lead nut to keep the nut fixed...
