Perry: Since it has a microprocessor-based regulator, my best guess is that it is a DC generator. Voltage control with an AC machine is not easily accomplished over a significant range.<p>If you can examine the voltage regulator and find its voltage sensing input which is probably some form of volta...

Shifting the phase angle 120 degrees forward and 120 degress behind is what has to occur. If you use passive components such as capacitors and inductors, you must still maintain rated voltage on the phantom phases within a few percent and the motor must rotate wihin about 5 percent of its synchronou...
