    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,

    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
