Then why do the two DD45 motors with the only difference being the Kv have the torque output lines on top of each other in this simulation?

In you graph, motor B is limited by phase current off the line. The faster wind needs more phase current to produce the same torque as the slower wind.

Torque will be the same in the range where the power curve is the same. So, increasing power, by either increasing voltage, current, or both, with increase torque.

If you move the sliders so both motors are at the same speed, battery power and motor power will be the same, but the phase current needed by the faster wind motor will be higher to produce the same torque.

Exactly...Thank You.

Just so no one misunderstands...it is the battery current/voltage that determine the "Power In" and the phase current is what your controller puts out AFTER it converts the battery current/voltage and the phase voltage/current is also pulsed by the controller at the correct time.
