Hi Konehead

Thank you for your latest pulsed-DC motor coil circuit.
The orbo's driving principle is taking too much power; 10 times more than a normal driving circuit. Tried lots of toroids and it is much less efficient.
You know when searching for the hat and find the shoes? Thats what happened today. Got the speed up effect with a ferrite bifilar coil.
Short one winding and at the other one put a load. In my case, connecting 50 leds  is not affecting the rpm. When connecting  12V/5W light bulb rpm goes up and the filament starts to glow

Hi Marius! I saw that on your vid: very well done! :-bd
Could you try same but with multistranded wire, twisted and then untwisted? like in the Bruce's TPU: looks untwisted multistranded is sucessful action bringing near no resistance in the wires at high frequencies
Cheer.

Hi konehead

I have abandoned the orbo principal; it is not efficient.
The speed up bifi coil is like you said: one half of the bifilar is "dead" shorted with its leads together, and other half is the load. It is the only one that gives this effect. The other bifi coils that i tested, have not twisted wire like this one. I'll start to twist more wire.

I don't understand "the bifilar is "dead" shorted with its leads together", could you make a draw, please Marius :/ even with the whole connection: gen-wiring + load-wiring?

Ok for twisted working better here. But looks to me you took single wire for one and single wire for the other, and you twisted them both together. But what about 5 strands for each, something like that? could be too big coil? :/

Hi Konehead and all you guys!

My rpm metter doesnt want to function tonight; have no ideea why.
When the rotor is spinning free with no shorted coil it takes 70mA.
When shorting one wound of the coil, rpm goes way down and the driving coil is taking now 250mA.
When shorting the second wound of the coil rpm goes up until the driving coil takes 150mA and rpm stays there.
So there are 80mA losts . That's why i said before that i dont see how we can use this effect since there are 80 mA lost.

On the other hand, if we can take that output and put it in another driving coil, this should rise the rpm reducing the 80mA lost. (i think).And the first wound of the coil can have a low resistance load, not necesary dead short.( i think)
I have tried this but the output is too small.
I forgot to say that i have build other bifi coils with twisted wires on sewing bobins and non of them had the speed-up.
Seems like if I want another , must replicate the existing one.

Hi marius,
    Good thinking, if you load the first coil with a bulb what would be the amp draw? does it still take 250ma? then load the second coil with a bulb, check again the amp draw? is it still 150ma? does it speed up? then try the coils in parallel is the effect still there? if you can make use of the power of the first coil not affecting the speed up then the lost 80ma is put into use... just thinking? thanks for sharing... keep it up!

Hi Mariu
Actually I wouldnt be discouraged since as you say it is an actual 'loss" of 80ma having the coil next to rotor, even if you get the speed up effect, since the simple solution is have an odd number of those twistedBIFIs with ferrite cores arranged around the rotor - with jsut one, sure it will cause some rpm loss, but with the right number of coils in an odd number of postions (usually one less or one more than the even muber of rotor magnets just like the 8 vs 9 romeoro machine)
then when you get to adding magnets behind those cores too, now you will get a speed up from  from that so when you add the speed up from the load like you have, now you got a looper...
I am finding out the magnet-postions behind the gernator cores is INDEPENDENT of the gernator-coil's cores positioning...in other words, place magnets around stator plates to get maximum speed up (Howard Johnson effect) then remember where the magnet sgo and theri strengths (how many in stack) then add the gernator coils with  their cores and rearrange abit to compensate for cores-reaciton too...have loads on coils when you adjsut the backign magnets like romeoro said to do....you have kind of skpped-over the backing magnets part of it - but have jumped on top of the speed-up effect under load to a coil! so maybe just make alot of them, place them in odd numnber of postions, then add magnets behind t hem all and you are there...

Hi Konehead and all

The long expected ''divine intervention" is here:

Hi marius,
more hints for you to try...

1- At certain speed the shorted coil will self oscillate... check here to get more info http://www.youtube.com/watch?v=iJsVSMQqCOM
2- A bifillar coil where one of the coils is not equal in lenght to the other one is another thing that you need to start to investigate now
3- A multifillar coil where each one of the coils is not equal in lenght to another one.
4- I have originally started exploring this in solid state version, with the help of the oscilloscope
5 - Difference of one cm in lenght can make a big difference  -  this is one of the reasons it took me very long time to get it right.
6 - The other things about the split core I told you before... make sure you can adjust the 2 split core pieces.
7- Distance between the magnets not less than 1.1% the magnet size but not more that 1.5%, you need to visualize the existance of the virtual pole in between the magnets.
8- This info can be used in other experiments, you can also have a look at Dave45 suggestions
9- Start the easy way, simple is better.
10- short at the peak of the wave without any aditional component, just the right lenght of a shorted coil

I hope this info will bring some light to some open mind people.

Best regards,
Romero

These are new things to try. I can not get more rpm's with only the magnets behind. Tried this for allmost a week changing magnets and rotors.
For now i cant replicate the speed up bifi coil on sewing bobin, so i must make other identical to the one that works (this will take time due to my new job that takes me all the free time).
What i want to try ( once i will replicate the bifi coil) is to make a bifi coil that gives at one side 12V with the other side shorted. This way i can loop back to the driving circuit or put all that power to another driving circuit.
