power = current*pwmDuty.

But the problem is, 500 amps * 0.01v = 5 watts, and 0.01 amp * 500v = 5watt.

When the rpm is 0, the motor is almost a short circuit. So, to allow very very small pwm (very low power) still allows for big current. I don't see how throttle = power allows for control of current at near 0 rpm.
