You have not been very forthcoming in your information, so it has been very difficult for people to help you.

We understand, you need a motor with variable RPM. Yes, this is super simple - it could be as simple as a Radio Control Car Speed controller and brushless motor, or as complicated as an industrial 6-axis CNC...

I am looking at your picture and it appears you are using a 12V fan as the motor/rotation source. Is this motor sufficient power? if so just buy a Fan control unit for a PC, very cheap.

Is the motor not strong enough? How fast does it need to go?How much torque or force does it require?

People here want to help you but you are being very secretive about it, which makes helping you very difficult. It's not a matter of people not wanting to help you because you are inexperienced, it's that they just don't know what you need - and you won't tell them.
The 12v fan isnt much strong... i need a bit stronger.

I really need the thing from this link, that would be perfect... but i must know what exact to look for, so i can see if its available here, or to look it up on ebay and buy the cheapest i can... I dont need cheapest per se just dont want to make mistake and throw my money when u can help me find exactly what i need

I need it to spin like around 1: 53... slow but variable about that speed... it doesnt really need much force it will only spin and not carry much weight maybe few grams.

I have this motor and its spinning fast... now it would be perfect if i could connect it to controller like in first post...
