ideaI have been running into linear motors and wonder what they are and how do you control them? From what I hear they are great.
i would love to use them if possible. If they are what they are cracked up to be. So what is the skinny?HELP

Sorry about that, i do not know what i did. here is what i wanted to say.

I used them when I was an engineer at a fortune 100 company. The short answer is great, very fast, and super expensive. I used Compumotor, commands were exactly like their stepper motors.

You'd need a really large one to replace an inexpensive step or servo motor and ball screw; so much mechanical advantage here. Might be possible for router where speeds must be high and torque needs not as high,

do you use the same controller as a stepper. 4 or 6 wires ect? or is a special controller?

Man, I'm not positive here. It would depend on each vendor's offer. There's no reason they can't just be standard steppers, electrically. The compumotor unit I worked with had encoder feedback for fault condition only, you wouldn't use that feature on a hobby CNC
