They offer HUGE horsepower, but no indication they are designed for
servo use. The things they don't specify is cogging, torque ripple and
velocity ripple. If these things are high, you will get "lumpy" motion
at low speeds. Also, they mention "capacitors included". If these
capacitors are large, they will fry a Gecko or Rutex drive. Or, possibly,
the Gecko will fry the capacitors.
