Muller Dynamo

[bolt]

Just got home from work, going to play with my motor in the garage. Last night I was playing around with it and I am having issues with the 2 ohm drive coil pair, they want to much current. But on the flip side I have gained rpm from 2300 (old coils)to over 5000 rpm. I must admit that I get scared running it that fast with no protection from flung magnets.... But the bigger problem is that it is really heating up the transistor. My circuit is similar to what Romero used and his coils were low ohms (2?). Any ideas how to cool this puppy down without a micro controller? Also has it been determined that the bucking coils is the way to go? I have lots of testing to do, but first I must have a stable drive circuit, so that is what I will be working on first.
Peace

Depends how far you want to go with it. Ideal motor drive is pulse width adjustable trigger AND PWM drive the coils during the ON period. Then you have max effect of control on the drivers while minimal  losses. That said you don't get OU from the drivers they are only a means to provide rotation. This was stated by Romero back on about page 3.

In references made in this thread, a bucking coil arrangement as I understand to be is two DC charges bouncing off one another.


Has anyone ever tried bouncing an AC charge off a DC ?

And also maybe tossing in a intermittent  ground connection, just get more bang for the buck, so to speak.

Or wood that be too wacky to try ?

Star coil is from like 1960 nothing new,, very strange behavior but it has been done, Rodin coil is the same if not older.

In the beginning I asked for help in locating 3 wires that I could not find as well as 2 wires that were not anticipated..... no body followed up until wattsup started carrying on about one of the two wires, BOTH wires from wattsup I found and posted pictures of BEFORE, if wattsup did due diligence he would of found the same info I did, now back to the point.

3 Connections from R's coils are to small to see nicely,, too small on only 3,,, not to mention a few extra diodes that change between videos.

What I have found is that if you take and inject a higher voltage lower amperage signal within a coil connected in series the ball game changes.

P.S. soft metal makes a very good inductor if set up right.

Thank you for your posts and in particular confirming the 2 unanticipated wires. Since this thread is now 290 pages long, can you please tell us the reference to your previous posting of BOTH wires please? I think this will put to the end of the nonsense of Romero connecting the X and Y wires to a battery and maybe we will have a good clue of what Romero did with these extra wiring to make his device work although the design may not be reproducible easily. My appreciation.

Hi Webby,

Want to tell us more?

Give us something to exp with please?

Hi Webby,

Thanks for that.

I am sure that many of us looked at the deceptive simplicity of the dynamo and thougt, I can
build that. Well, I gotta tell ya -  It ain't what it seems.

Many of us would jump at the chance to build a device that could either selfrun or
display OU.

A new thread for a new device sounds appropriate to me.

LEAD THE WAY!

Kindest Regards, Penno
