Well, it depends on how you define an ideal motor. I am having trouble grasping what it would mean if a DC motor had no internal resistance and still followed the traditional equations with Kv and Kt and the rest--does this mean that it would always spin at its free speed for a given voltage, no matter what the torque or current going through it?
