Hi,

I am building a gantry robot and for the Y-axis I am using a 1610 ballscrew (16mm diameter, 10 pitch, 1300mm long). I estimated that the mass is 36Kg and for the speed I planned to have 1800mm/min.

Using these calculations I concluded that the total torque is 0.23Nm. From the Excel the estimated torque resulted to 0.67Nm.

Now I have the following questions:

1) Can I use there calculations for a ball-screw system?

2) What is the calculation to determine the estimated torque (0.67Nm) from the total torque (0.23Nm)?

3) Is 0.67Nm enough for such mass? I did some research for similar projects and they use a much higher torque stepper motor.

All kind of help will be appreciated and sorry for my bad English.

Thanks in advance.
