  • How to calculate motor drive torque for ball screws

    This article explains how to calculate the back driving torque. Aside from being necessary to move the load or execute the process as desired, the required motor torque also determines the amount of current needed from the servo amplifier. When current is applied to a motor, it encounters resistance and, as a result, heat is generated. This heat is commonly referred to as I 2 R losses (I
