Our friend Fred from BST Automation has 1kw servo motor + drive for 332euro +shipping which will cost you in total~400$ for the combo when you buy 4.


I am not sure you need exactly 1kw if you go with rotating ball nut. But as prices are similar. I think you will need 0.75kw geared like mine 20t:30t and that will give you speed of 20000mm/min on the long axis/ball screw with rotating nut/.
