Circuit setups for pulse motors

[Ren]

@ the toad. You are right of course. Conventional science says current IS everything. I have just been reading alot of interesting stuff lately that has steered me in the direction that current may not be all it is cracked up to be. Of course I have no legs to stand on, having no scientific proof of my own. Like you say prove me wrong! lol its a bit like the apprentice dueling the ninja master at this stage! By the way toad I am really thankful for all your input, I cannot seem to find your info on coils at the moment?


Paul, Im interested to hear your theories, and I also have some more schematic ideas for you that I will post up.

Perhaps try sticking to the original bedini setup? Heres one with two coils, well actually four coils, (single wind) two to trigger and two to fire.
Join this group here if your interested in studying the monopole motor and learning some simple efficiency tests. Schematic here is from this site.

Keep tickin

Greetings Ren. The Index page only had really minor changes so you are probably getting the old page cached,
try revisiting and then Refresh the page. If that doesn't work heres the new page 4 direct.
I hope you find it interesting. Ive actually added alittle bit more info since I posted it last night.

Cheers all!  From the Toad who Hops

Hey Hoptoad. Some great insight as usual. I suspect the configuration is more important than the alloy used in the wall anchor sheath. I will try a soft iron pipe with holes drilled at the center (bloch wall). Have you heard the Phil Woods theory of "4 poles"? Ok, if you wind a typical coil, and have a center core to strengthen the field at each end,,, when the coil is energized and lets say end "B" is a North pole, the "outer circumference" of the coil at the "same end" is a South pole. This is an opposite polarity and equal at the "A" end of the coil. YOU HAVE 4 POLES.
Not what I learned in science class!!!

Hi Tropes,

I hope all's well with you. I had heard of this theory back in the early 80's and have tried it out myself during my pulse motor experimentation era.
I don't recall who it was associated with, I just remember reading it somewhere.
Alas, what works in theory often has a strange way of  working but doing also something completely unexpected in reality. When used as a generator/motor coil in front of a single magnet pole, it yielded extremely poor results in my own experiments. The duel cores inductances are actually self cancelling. The reason will take a page of description and diagrams to explain. Whew ! more work!  But I must say that it is worth an explanation. I will try to come back to this subject after I've finished covering a little more ground on pulse motor design. I've still got a lot to say in that area - probably too much! (LOL)

P.S. - I can't overstate the positive aspects of the "Alloy" nature of the sheaths. When comparing like for like with ordinary soft iron which I did in later experiments, it became very obvious that the huge gain in voltage and current availability was due to the nature of the core material. (The shape still matters - see updates on my site) But dont stress over this, because I am sure that it is not some Exotic once only fluke alloy, but is widely available and at a cheap enough price even at retail, that you can save yourself the time and trouble of repeating all the experiments with soft iron tubing and just go out and buy them pre-made. Still, experimenting is a pathway to understanding!


Cheers from the Toad who Hops.

Awesome stuff mate. I love it. I was reading about the late Bill Muller recently and he noticed the benefits of amorphous metals in coil constructions. Have you seen the gemini motor by chance? It runs on a similar principal to what you explained at the bottom I believe. Check it out here.

As always mate, a pleasure to read and learn from you.

Gidday Ren, I hope I'm not leading you up the garden path, but I will eventually lead you somewhere?? 

It's good to see you asking comparative questions and making comparative statements.

Bill Muller had an inkling or two about magnetic dynamism. It is sad he has passed on. His designs utilising odd/even core to magnet ratio, highlights an important issue surround magnetic drag. That is the "cogging effect" which takes place in pulse motors with iron cores. This "cogging effect" can become so pronounced at high speeds, that a standing vibratory wave takes over, and threatens to shake everything out of its otherwise stable behaviour. At certain frequencies cogging is nasty! The trouble is that those frequencies vary with the diameter, number of magnets, and moment of inertia and speed of the rotor.
At speeds from 5000 rpm to speeds of 10000 rpm, a smoothly rotating rotor can quickly become a monster!

The Gemini Motor is a very well designed "Closed Magnetic System". It is a classic KISS and lets do it this way, its better!
And it is better than most motors on the market. So I wouldnt want to change it. It works very, very well!

Open systems are a "different kettle of fish". Not necessarily better one. But they exhibit a particular phenomenom not present in Closed Systems. This true of "ALL OPEN MAGNETIC CIRCUIT MOTOR SYSTEMS".  Will explain  ....    soon ...........
They are worth pursuing for the revelations they have to offer in their own merit.
