Hello all,
I am Stefano. I visit your site a long time ago but this is my first time i post in your forum.
I have a motor that has a long screw on it's rotor. This screw rotates and moves a nut. on the nut, i have the load of about 14,5-15 kilos. I do not know how this assembly is called but i hope you understand what i mean.
The step of the screw is 8mm per rotation and the diameter is 22mm. I took it from an old machine that does not work any more

I want to lift this weight about 3 meters. Can anybody suggest me what kind of motor should i use and what speed can it run? I do not want it to be very slow.
Thanks a lot people!
