Thats interesting.  How many meters do you have? I imagine you would see an increase current draw on the battery when slowing the rotor due to the longer on period. I wound my coils a while ago but have not had a chance to do anything with them. Have you posted the circuit you are using? I can throw a pulse motor together pretty quickly so I’d like to see if I can replicate what you are seeing. Thanks for sharing

YES..  Increase on current draw and increase in both current and voltage inside the circuit when slowing the rotor.
I have a few other meters, but I don't trust those $4 harbor freight ones much.  But I do have some analog current meters I can put inline. 

The rotor and motor is not even needed..  All the rotor is doing is timing the polarity flip.  It works the exact same just skipping the rotor and flipping polarities on the quad pancake  between 20-60 Hz.   I haven't experimented much without the rotor yet, but within that frequency range is where I am seeing comparable gain results.  The gain seems to peak at about 25 Hz for me.

I am using E core electromagnets clamped together. I am not sure at the moment if the first e-core pair is repelling or attracting each other. And I am not sure if the last set of electromagnets is even needed.  But since it was working good like that, I haven't touched it.


(note- image is showing a regular tesla pancake, but I am using that crazy wound one that is not standard)
