Motor run as a circuit element?

    Can you convert simple current in a wire to mechanical energy with a motor? What type of equipment would this require.

    I'm not sure what you mean - that's what a motor is for.

    Sorry I was unclear. Is there a particular type of motor that converts current into mechanical energy without using magnetic materials?

    actually nevermind, let me think it through more thoroughly and decide exactly what i'm looking for.

    Most electric motors use some magnetic phenomenon to work. Remember that any current through a wire generates a magnetic field, so it's not something easily neglectable. There are motors out there with very good magnetic shielding, however.

    I think that Neal might be asking if it's possible to build a motor that doesn't include permanant magnets. If so, the answer is yes.

    Basically to put it more clearly, I want something that I can connect to a current carrying wire that will create traslational motion, like a move a small cart of wheels.

    Okay, then... I think that you are basically looking for a linear-induction motor. They don't just follow along a wire, though. There are magnets and polarity-switching involved.
