RE: I'll bet...

As I stated earlier, I really don't know much about electric motors, but from what little knowledge I've gleaned recently, it seems that brushless DC motors are actually AC motors in the sense that without brushes and a commutator, the motor controller must switch polarity to the motor coils in order to make it run. Therefore, the motor controller is essentially providing AC power to the motor instead of DC power. Usually, the AC power takes the form of a square wave or trapezoidal waveform, but in this particular case the stationary coils are receiving true 3-phase sinusoidal power in order to eliminate cogging. In other words, the motor coils are connected in either a Y-configuration or a delta configuration. Therefore, the Condor motor controller converts DC to AC instead of the reverse as you suggest because the Condor is powered by a 24-volt DC wall-wart power supply and must generate 3-phase AC power to send to the motor.
