3 Pole Kit from Rennaissance Meeting

[redeagle]

The "classic kit" that i just received was shipped with MJL21194 transistors. I have had no problems with them so far. I Would make sure that your collectors are isolated from each other. That would affect the reading of your transistors. i have observed with mine though only briefly that if the charge battery is disconnected that the master coil does not light up the neon even though the coil is firing. if your collectors aren't isolated that could be impacting your scope reading. Once you ensure that the collectors are isolated i would check to make sure that they are all working.

On a side note I would hope to see additions to the kit to include adjustable hall switching and attaching additional rotors, coils, etc for further experimentation on this entry level platform. currently a timing gear is the only thing available. Hall switching offers benefits over the trigger circuit for both tuning and charging.

My collectors are all isolated per the schematic with only one side of one diode and one side of one coil connected. They are all firing, I checked each collector with a scope.

As a side note, at first I had all the coils (trigger and energizers) with the leads reversed and it ran exactly the same at 5000 RPM only when the bottom trigger coil was to the far left or right and had the same COP of .3.

Hey guys,

I've had my 3 pole kit now for over a year. I have come up with a different circuit similiar to the half bipolar circuit, but even simpler. I'm using the 3 power coils but I am not using the trigger coil wire on the bifiliar coil. So you could just use 3 single wire coils. I am putting the spike back into the input battery so I use only 1 battery. My best tuned set up runs on 12 volts 40ma and the rotor turns a little over 3300 rpm's.

I was wondering if anyone has their 3 pole running at higher rpm's for 40ma@12 volts input or over 3000 rpm's with less than 40ma @12 volts input?

I'm just trying to figure out If I have a good circuit here.

Thanks, Mark

Hey Mark, can you post your schematic so I can replicate.

[Mark]

Parts you'll need:

21194 transistor
21193 transistor
1N4007 diode
33 ohm resistor
550 ohm resistor

I hope the diagram shows up never posted one here before.

Mark

p.s. upload failed. How do you upload a 1 page scanned page?

Hey Mark, can you post your schematic so I can replicate.

Ricardo,

I'm not able to upload my schematic the file is to big, my computer is too old and junkie, or I'm just not doing it right. If you PM me your email address I can email it to you.

Thought this might be of interest and is topical.

This is 2 off topic posts between Chuck H & John Bedini on the: Bedini Ferris Wheel Regauging Motor. Post #487 & #488.

This is in regards to running the 3 pole kit using a hall switch in place of the trigger winding. There are many advantages to this including lower run amperages and more straight forward tuning.IMHO.

Has anyone here on this thread tried this?

Update on 3 pole kit. Now has hall switch. Still need to take readings on everything before next step. Does not self start yet. But I think I know why and will reconfigure it after I take some readings. Then will install cap. Starting to understand johns big wheel a little. Once this is done mabye i will try it on a larger scale... YouTube - bedini 3 pole with hall switch 12 12 2010 3 56 PM

Chuck,
Ok it running, now move the rotor to 1/2 the pole piece and adjust the timing and it will self start. First it will go backwards then it will start.

I plan on trying this in the near future.

Happy building.

Thanks!

I really liked the self starting part of John's post.
Haven't tried that yet.
Definitely have followed your (P&S) wonderful work over on BM2.
Thanks for the welcome. It was my first post on EF.

Hi Stephen,
lots of fun to be had all over the net eh
We can't get our little 3PM to self start yet - still trying. We've advanced retarded coils... adjusted timing wheel etc.. was there some simple sanity to the madness here? help...
we posted some tips on getting familiar w/ halls both in the monopole threads and here http://www.energeticforum.com/renewa...tml#post116913
lots of good helpful people all over the place these days, nice

I also would be very interested in your circuit, sounds like a good one! I am hoping to start playing around with the bipolar setup and see what that gives me for results. Then its time to play with halls! How does your charging work out?

I have been able to get the kit to run up to approx 3000RPM's with 40mA or so but only when I have my pot on the trigger cct turned up which is reducing the current gain on my drive circuit. For my setup that means smaller radiant spikes since the magnetic field is not allowed to fully establish before it gets shut off.

I am still a little confused as to the best ratio of input current to output radiant... only time and tests will tell.

Also what I found was interesting (if not necessarily usefull)
By putting some neo's south pole onto the back of the drive coil you can see the input current go way up and also the radiant spikes. My thought is that by doing so the core of the coil is getting saturated and there is a reduction in Lenz for the establishing magnetic field in the coil. This allows more current to flow in before the field sets up and also a bigger collapse when shut off as the field contains more energy. As an aside I intend to play with this idea a little further once I design my own setup and cutom wind coils since I am intrigued with the idea that I might be able to create a bigger collapse by the use of a permanent magnet's field...

Hello Kippered

I've done some side by side comparisons with the new circuit I used compared to the half bipolar circuit and although the newer circuit is simpler, uses less parts and doesn't use a separate trigger coil it doesn't appear to run more efficiently than the bipolar circuit. I was dumping the spikes directly back into the input battery so I haven't done any testing to check charging a secondary battery. If you PM me your email address I will email you a schematic. Everytime I try to post an attachment I get an error message. My computer is a dinosaur, lol.

I was more wondering if you see any charging effects on the input battery with your single battery setup, or longer runtime etc.

I pm'ed you re: e-mail if you want I could try and post the schematic for you.

thanks!

[Mark]

Hey Kippered

I emailed you the circuit. No over unity with the circuit or actual charging of the input just recirculates the spike back into the input battery. Feel free to post the circuit so others can play with it and possibly improve on it.

thanks Mark here it is (hopefully)
