My first unit to achieve 1 for 1 charging!

[Woody]

You do know battery voltage increase with heat? of 27mV per 12V (0.108 per degree C 48v) so if your battery was outside at 10 degrees C and your house was 20 C it would RISE up by .270 volts. All by itself! Just to let u know that's all. Nice neat machine.

Thanks for the data machinationus. I am aware of temperature effects on batteries. In this case, the battery is in a section of the house that is not connected to the heating ducts. It does get quite chilly in there during the night, so there was definitely NO ambient temperature rise. In fact, the temperature had dropped during the night, so the voltage rise cannot be attributed to heat.

I am noticing that the larger batteries produce some interesting results compared to the smaller batteries I have been working with. Now I see why J.B. says to use larger batteries! With 19 awg motor windings, and 6 motor coils, this unit is now better suited to larger batteries. What a hoot this is!

Ahh that is what I thought you have a different rotor, that is the latest rotor From RF. the other style rotor has round holes, not slots.

No problem! Here are some pics of the rotor, Tom. It is installed, so kinda tough to get a good angle sometimes but these should be good enough.

woody,

put up some pics of your rotor if you can.

WOW!! Hey y'all, I just converted my mini 6 pole unit to a superpole, and the difference is amazing! I found some rectangular SmCo magnets that will fit in the updated 6 magnet rotor that r-charge used to sell, so if you have that one this conversion is a piece o' cake! Those magnets can be found here: cPath_3 | products_id_249 | SmCo Magnets 1/2 in x 1/4 in x 1/8 in Samarium Cobalt Block Magnet - Applied Magnets & WindMax Wind Turbines

Ok, for those that have not been able to remove the old neos, or who just have not tried it yet here's how I did it. Get a wire mesh basket (I think it's called a strainer) and a pot of water to rest it in. Put enough water in the pot so that the water does not touch the basket when it's resting in the pot. Steam the rotor for about 30 min or so. The magnets should come out with a little help from another neo and maybe a few taps from a screwdriver.

So, ok now for the results I have from this conversion. First of all, when I had the regular small SmCo magnets in there, the unit really liked to run with only 4 coils. This was optimum for charging and gave me my first unit to have a 1 for 1 charge capability. A 5ah 12v motorcycle battery would take about 3h 20m to charge to 14.8v, leaving about 12.02v left on the primary at shutdown. The primary would recover to around 12.45v one hour later. A 9ah battery would take about 7h 19m to charge to 14.1v. The primary would be at 11.83v at shutdown, and would recover to 12.25v.

With my new superpole rotor, the unit likes to run with all six coils much better. I moved the coils a bit further away from the rotor for a distance now of 3/16". The 5ah battery charges to 14.8v in 1 hour!! Load testing gave me 2h 8m at c20 rate, so it's not surface charging. The 9ah battery took about 2h 30m to raise from 12.28v to 14.14v. Load test gave 3h 44m at c20 rate. I won't post any pics because the unit looks exactly the same. The only change is the addition of the superpole magnet equipped rotor. My new data shows 880ma draw on primary, and 470ma input to secondary. It runs at about 4300-4500 RPM, and I'm running 15.2 ohms resistance on the trigger. Also, the unit is now a 1 pulse per magnet machine, with spikes of about 340v.

Right now, just for fun I have it charging a sulphated 690cca battery with a 550cca battery I have rejuvenated. It is doing very well. After a total time of 2h 55m of charging, the bigger 690cca battery has been raised from 12.37v to 12.93v. The interesting thing is, I started charging it last night. The primary started at 12.71v and the bigger secondary started at 12.37v. I ran it for about 1h 45m and shut down the unit for bed with the primary at 12.45v and the secondary at 12.86v. After the initial drop on the primary at the beginning of the run from 12.71 to 12.39, for the next 50m the primary was INCREASING in voltage! At shutdown last night the primary was at 12.45v, and check this out. This morning when I went to start it up again, the primary was at 12.72v!! Higher than BEFORE I started the run last night, and after running for 1h 45m! The secondary was at 12.49 this morning when I started charging again. So both batteries were at higher voltages this morning than they were last night BEFORE I started running. Is that cool or WHAT!!

Anyway, I just wanted to give an update here! There is lots of fun to be had with this little unit. If you have one, you can learn alot with it.

Hi Woody, nice one for the schematic. Have you tried doing the timing using electronics, rather then the wheel? This part looks a bit unelegant to me. Btw, a quick progress report on my own efforts: I tried experimenting with different sweet spots after reading your original post at the top of this thread. I tuned it into its 3 pulse sweet spot yesterday, and got an outstanding COP (for me at least) of 2.21 on the battery, and .65 overall. I'm gonna try the 4 pulse sweet spot tomorrow, and see if I get the same kind of COP improvements as I did at three. Maybe unity isn't as far off for me as I thought ( .. he says optimistically).

Hey Rob,

The SSG part of the circuitry is just standard single trigger, multiple coil layout. Nothing special at all. Here is a cheesy hand drawn diagram of the cap pulser. Sorry it's kinda lame, but it should explain it.

[Rob_Esq]

Hi Woody, I thought that they were intended to do something like that. Thanks for the vid. Do you have a circuit diagram / schematic for this build by any chance? I'm getting a COP of around 1.75 on my chargeing batteries at the mo, but my overall system COP is a poor 25%, so I figure I need to start thinking about how to make it more efficient, and capture some of that wasted energy. R

[Woody]

Rob-

The generator coils produce A/C, and provide a means of loading the system mechanically which reduces the current draw on the primary while also extracting useable electrical energy. I have used the output of the generator coils by rectifying the A/C, and then sending it to a capacitor for dumping to the primary. This produces a nice increase in COP. I have some videos of the unit in action, but they were shot before my most recent rebuild with the 19 gauge coils. Here is a short video showing the gen coils and pulser in operation. In this video, I am running at 24v.

[Rob_Esq]

Hi Woody. Have you had the generator coils working at all? Please can you explain how they work a little bit. Thanks .. Rob

[Woody]

Teo- Here are some more pictures of the machine.





The yellow coils on the rear of the machine are not being used right now. They are generator coils, and I usually have a second rotor mounted on the shaft. I have that assembly in place to provide a third bearing which stabilizes the long shaft, reducing vibration.

@Branch- Thanks! I just ordered some rectangular SmCo magnets that I intend to arrange in the super pole configuration on the rotor. That will be my next modification. Also, from the initial tests at 24v, it appears that further enhancements manifest at the higher voltages, such as being able to activate the other 2 coils while actually lowering the current draw. I still need to do more work on this though.

@Rob- I have heard that the number of spikes that are optimum really varies from one build to another and
I can verify that maxim. My bike wheel likes 1 spike, but this 6 pole running at 12v with 4 coils activated really likes 2 spikes. When I reduced the trigger resistance down to the point that I had 1 pulse, the current draw on the primary was huge, the thing ran super fast, and components heated up. Yes, the spikes were huge too (800v) and the charging was obscene, but it crossed the line. The primary discharged too fast, and the charge to secondary was largely surface charging with traditional current. We want radiant and some traditional positive component together to obtain the best results. It has taken quite a bit of tweaking on this build, but I seem to have finally struck a good balance.

@Teo- I am away from the lab for a bit, but when I get back I'll take some more pics and post them.


A bit more detail- The coils are 212 turns of 19awg motor windings and 23awg trigger. Base resistors are 100 ohms, and the diodes are higher voltage. The smaller is the 1N4007, the bigger one is a 3a 1000v diode. also, I have 4.7k ohm resistors in series with the NE-2 neons.

@Woody,
Thank you for your reply.
can you show us more pictures, from different angles, please?
Wishing all the best,
Teo

[Rob_Esq]

Excellent news Woody .. nice one! I've been lead to believe that we should be aiming for one pulse per magnet, but I see that you are getting results from two. How does your machine perform with just one spike? Any thoughts on this? Rob
