Thanks for posting this video link.
It inspired me to try to rewire my single bifilar pickup coil to simulate it seeing a "South".
In the configuration that i have it now, i see for the first time a significant speed-up under load when i attach a neo magnet at the end of the coil.
Also the rotor starts up to speed much faster, which indicates an aid in push.
I believe that this is mainly a magnetic effect to reduce the Lenz effect.
Remarkable is, that i see pretty much the exact same waveform that Romero posted. Maybe the waveform combined with the magnet is doing the trick.

Great xenomorphlabs,

now you are corroborating some of my findings. The bias magnets do make a huge difference.

Also last night I changed which driving coils I am using and I have a huge surprise on the outcome. I was using two opposing coils (one pair - one on top stator and the other on bottom stator) being driven by one transistor. Than I decided to change the driving coils so that I use one coil on top of the stator and the opposite coil on the other side of the same stator (cross the stator) for the second coil. So both coils are on the same top stator. The difference in speed was dramatic.

I can run this motor for less input power an amazing 1350rpm with the load generating 7v on the cap and 60ma on the lamp. I did not even use another transistor. So one transistor driving two coils of opposing positions (180 degres apart) and still the acceleration was amazing.

Fausto.

I do not wish to be offensive but you waveform is not like Romero's.

Please see this pic (left waveform is from http://jnaudin.free.fr/html/mromexp.htm ):

Well, take a closer look at the current waveform. Might change your mind.

Irrelevant now what is the i/p ration .99. I see you drove the questions so that the conclusion is obvious, no OU, YET!!!

I need help here. With your skills I would love to "know" why I have those spikes. Do you? There is nothing special on the circuit or the output circuit. Just magnets passing by a coil with bias magnets behind. One should NEVER have those spikes there, correct?

Now it would be a great moment for us to speculate what could be the reason behind those spikes and ways to test the hypothesis speculated. I still have the motor so good timing now.

Fausto.

ps: .99 forgot to say, thank you for your comments and your inquisitiveness

Sorry if this has been covered already. I am catching up and am still a few pages back from the newest posts.

Could the spikes be when our "virtual switch" of the FWBR voltage drop and Dump Cap voltage does it's switching? Basically the coils do not see the load until their voltage gets higher than the FWBR V drop plus the V level in the Dump Cap each cycle. But at the moment the coil o/p V becomes greater than the sum of those two V drops, it immediately "sees" the load and tries to send current. It is the same reaction as flipping a light switch. And may result in spikes?

Your "Romero's picture" IS NOT Romero's picture. I am confused about your statement. That picture you showed is nothing to do with Romero's.

Fausto.
