Artist in need of help

[dmhmaestro]

It is a NEMA stepper motor and to make it rotate you need some electronic circuits. These can be (but are not limited to) Raspberry Pi, PC Arduino and a miriad of other options that would be far too long to list.

What you choose to drive it with does depend on what you want to do with it but whatever you choose it will need programming in order to work.

im very suprised that it is that difficult to achieve... we see tons of motors and just this task to make it variable rpm becomes so hard... I really need this because im making something extraordinary ...

I need detailed guidance in how to make this motor... The motor will not have much friction in its purpose it will have contact with ferrofluid and thats it... So , i would need to buy stepper motor and what more? couldnt i just buy some know controller?

something like this?
