There is no control circuit. It is simply a contactor. Look at the picture above it. See the Gigavac contactors? That's all there is. That grey control box only holds a primary on/off switch and two momentary pushbuttons, each directly connected to a contactor. There is no controller, no "reference" current level to oscillate around. The current simply peaks then decays. That second peak is simply me letting go of the contactors' "on" buttons, probably because the thing jumps to full speed and it's difficult to hold onto the the control box, two buttons and not fall out. The two peaks don't exist in any of my other tests because I learned to drive.
