good stuff
i don't see the diode blocking pulse in your waveform like i see in mine, also one of your phase pulses looks bigger than the other two, why would that be?
i calculated from one of my waveforms that the alternator and cell would resonant at around 13 kHz but I have not pulsed the rotor yet to try that
the way to calculate it is after the diode blocking pulse the coils ring, like it's striking a bell, this ringing frequency is the natural res freq of the system
