Hi.

I need help for sizing my stepper motors for my project.

I am using lead screw 6mm pitch with mean diameter of 17mm.
The weight on z-axis is 15kg, on y-axis is 30kg and on x-axis 70kg.

I am using linear recirculating ball bearings on the y and x axis.

can anyone help on motor sizing. is there any formula i can use?

Thanks
