Have you priced linear motors lately? They do sell them by the foot, because either the windings or the magnets have to run the full length of the travel. You also need a position feedback device (encoder) that long, and that will also be quite expensive.
Also, just because the motor itself, is non-contact, doesn't mean the entire AXIS is non-contact. There still has to be some kind of guideway with rollers of some sort to keep the motor armature from slamming into the magnets.
