Reminds me of my stepper project.. Since the stepper's output is high frequency, I was able to reach resonance of a secondary of a transformer.. It resulted in speedup under load..
My evaluation is, when we reach resonance, the sinewave shifts by 90 degrees, thus negating Lenz. So it runs Lenz-free. This does not account for the speedup effect though.. IMO, when we neutralize Lenz, we also neutralize eddy currents as they act the same way as Lenz drag.
So when we spin the motor unloaded, we are still fighting eddy currents from the cores.. But when we harvest a load, both the Lenz from the coil + the drag from eddy currents get atleast partially neutralized..
This theory coincides with the observation that, Although we can get speedup effects, we can NOT make the rotor travel quicker than if there was no generator coils or cores.
I always wondered, if we reproduce this setup, then amplify the output with an amplifier, would it enhance the neutralization and allow the motor to spin even quicker.
