I need to acquire the motor shaft (Jm) and drive screw (Jd) inertia to calculate the equivalent moment of inertia reflected on the motor (Je = Jm + Jd). Also, I need to acquire the axis motor's current (i) and the motor torque constant (K). This way, the Motor Torque can be calculated as Tm=Ki. How can I acquire them?

To acquire the motor shaft inertia (Jm) and drive screw inertia (Jd), you would typically need to refer to the motor and drive specifications provided by the manufacturer. The motor torque constant (K) and axis motor's current (i) can also be found in the motor's datasheet or through testing with a torque sensor and current measurement device. Once you have these values, you can calculate the equivalent moment of inertia (Je) and motor torque (Tm) using the formulas mentioned in your question.
