Anyone familiar with the Parker/Compumotor Dynaserv motors? I am trying to determine if I can drive this particular motor with another brand servo drive( Control Tecniques-Unidrive). I am really not sure if this a stepper motor or a servo motor or if there is actually a difference in the two. I always called it a stepper motor because I required a step+ and a step- signal to the drive.But in ome literature I was looking at they refered to it as a direct drive servo motor. Looking for some clarification.
