Ok, I will wait patiently.
I the meantime, I've been played with 3BGS with small 7 Amp Alum batts, load hooked to a booster (set to 36 volts), and then differential voltage (20 volt) to a REMF charger, charging the fourth battery. The results was somehow disappointing, which is normal, I think. The charge in third battery was inconsistent, not like the charge done before with the modified motor. This test failed big time, but I was aware of failure possibility.
Now I'm testing 3BGS using an inverter, wich give me some usable light at 800 mA current draw (inverter + 5 Watt led lamp). First cycle was very promising, BUT, I have to say now I'm using 40 Amp deep cycle batteries, and, it seems like resting time helps a lot charging the third batt.
Right now I'm running the second cycle, and the result looks, also, promising. Battery charged first time looks stable, and the charging process of the third battery seems to be effective.
After finishing all the cycles of the test, I will post results with diagrams.
By the way, light in the room is powered by inverter :-)


L.E. I updated this post with some Excel charts.

Short conclusions: main goal was achieved - third battery is charging for real with inverter.

Note 1: batteries was discharged only to 12 volt, though specs allow to be discharged down to 10,5 volt (FCD12-40AT batteries).
Note 2. all three batteries was not fully charged.
I manage to run batteries in 3BGS configuration for 35 hours, at 800 mA load, but this does not prove anything special, so far.
Anyway, in next test I'm just discharging the battery with inverter and led lamp, to see how long the load will last in real world.
I'm going to make a complete test using 3BGS configuration with fully charged batteries, down to 11 volts, only when my automatic switcher will be ready.

Best regards,
Teodor

Update

You guys should know that Matt has had some technical difficulties, which required a whole new operating system installed from scratch on his computer. And since it is now a Linux machine and he NEEDS to be able to run some specific kinds of programs, he now has to figure out how to run similar programs in Linux. So he is swamped with trying to get all this figured out just so he can climb back up to the baseline he was on before everything went to crap. He may not be responding for a while.

On another note. If you haven't built a MODIFIED MATT MOTOR and begun to learn how these systems work and WHY we believe they are so important, you really need to do that. One day you will be kicking yourself that you wouldn't pay attention when you had the chance. That day is fast approaching.

First New Year post

My first post of new year.

Sorry to hear about the meltdown Matt. Sure you'll be back real soon. My son-in-law wanted to switch me over to Linux but decided not to as I'm not the IT type. Plus my relentless calls would have made him crazy. LOL.

My modified Matt motor days are passed as I hope to move on to better days in the shop.

Will see what this year brings.

I finished winding another motor the other night, havenít compared running it yet to the before numbers, it does seem to run smoothly. I still have to check rpms and amps and temp.
I have been building the benitez switching as Peter demonstrated, hoping to have that finished soon, just don't get a lot of time in the shop.

I do IT. Working for a MIL contractor, I became a "real boy" started using PUIAS(Princeton LINUX - because it was closest to RHEL). I was able to do everything that I use to do in Windows, because I ran Windows 7 VBOX as a sub host. LINUX was just the protected wrapper, I could snapshot the WIN VM so If I felt any intrusion or anomaly I could roll back. The trick is to separate your data, and have network backups, while knowing what had to live where to function. Once you did that, you had a more powerful operating system without the direct access to kernel worries and praying zero day vulnerability would make you toast. ---jmtc

Sawt2,
Nice winding there. Just noticed you used single wire instead of bifilar winding. Don't know what difference it makes. I copied Matt's motor modification to exact as possible to get same results. He helped me very much answering my questions.

Not being negative in any way. Just my two cents of observation. Interesting to see your results.

Info

I did a little test today on two of my 12 volt batteries. Wired them in series and ran an 80 watt load for 3 hours and 10 minutes until battery voltage dropped to 12.5 volts. Don’t want to go lower than that. I also put the battery analyzer on them when they were fully charged and again when I was done.

Gonna run the same 80 watt load using the principles we have been sharing and see how long it lasts. Will run the battery analyzer tests on it also. Just for fun. Who knows HOW it will turn out. It all begins with understanding the principles, and THAT begins when you have a working circuit. Which requires a working modified Matt motor. Harp, harp, harp. That’s all I do.

lifetime of carbon brushes

Hi Turion,
According to your experience, to how many hours do you estimate the life of carbon brushes of the modified motor Mat MY?
Personally, I experimented with a ZY1016. When I bought it, I did not know that its collector had 20 poles instead of 16 as on the MY.
For good results, I found the solution that consisted in reducing a little the thickness of the carbon brushes, but the two that receive the collapse of the coils are now completely worn, after a hundred hours of operation only.
The other two carbon brushes are still good.

cordially
m12

Brushes

M12,
Unfortunately, that is a question I cannot answer. I never had a brush problem with the MY1016 when I was using them. But I never ran one that long either. I usually burnt them up. I soon moved to the MY1020 which is a bigger motor. No problem there either.

The My1016 stock or modified could not break the magnetic lock to start my generator and I burnt up lots of them. The MY1020 could start it about three times before it was also toast.

Once I solved the magnetic lock problem I put out enough energy that I didn’t NEED a modified motor and not having to wind them all the time was a great relief!! So I haven’t used a modified motor in quite some time. Just a stock motor with a 555 timer to get me the pulse I need. I can afford to waste energy in my circuits now because of what I get out of the generator.

On a small setup you just CAN’T afford to waste anything.

Battery analyzer

This is the battery analyzer I have been using. It is by no means an expensive one.

Can you be more specific, please? What is the capacity of each battery?
If the load was 3 Amp, and each battery was drained to only 12,5 volt in 3 hours, I think they are at least 200 Amp/hour...
Best regards,
Teodor

Batteries

These are the little lawn and garden batteries I am using for this experimenting. Generally I use them when testing a circuit so I don’t RUIN my good batteries. I have 10 of them, 2 that are Alum, and ten 6 volt deep cycle golf cart batteries.

When I get done running several charge and recharge cycles to get solid baseline data I can post all the info on the batteries and what my little Harbor Freight analyzer had to say about them. Matt has a tiny bit better battery analyzer that I’m pretty sure cost him about $3,000.00. So when he says he has analyzed a battery and knows what is going on with it, I would listen to him. (I actually thought it cost more than that, but he told me today it was $3,000.00)

I’m just testing to see how long I can run the 80 watts directly off two batteries. Then I can compare to running it on a circuit. Not sharing those results here though. We’ve given away as much as we’re prepared to and only a few are building or experimenting anyway. I will just pop in to encourage people to build the circuits we have ALREADY shown with the correct parts. They prove this is for real. Then you are on your own to experiment and take it to the next level. We just want you to know it works and there REALLY IS a “next level.”

Thank you for your reply. I've finished my first test, discharging normally my batt down to 10,5 volt, and the results are:
- run time 26 hours 36 min, at 0,8 Amp load (one led bulb) and 14 hours 33 min, at 1,42 Amp load (two led bulbs)
I consider irrelevant, however, my first results. The test with one led lamp was wayyyy to long, so i tried to add a second light, to see what happens.
I am now discharging again my battery, but this time at 2,07 Amp, to fit C20 rate, and this time I will go down to only 11 volts. Because in this test I am using 3 led bulbs as my main light in dining room, during the night, it will take some time to complete the test. So far are 11 hours already gone, and I think it will last only 14-15 hours.
So my hope is that 3BGS would last for more than 30 hours, in inverter configuration with 2 batteries fully charged, and the third discharged to 11 volts.
I will repeat later test with modified motor, but the noise is a big problem in my small place, I don't think my wife and kids will be happy... I have to find a way to cancel or to attenuate the noise...

L.E. OK, so here are the results of second test:
40 Amp Deep Cycle Battery, discharged normally at 2,07 Amp/h down to 11,00 volt - RUN TIME: 18 Hours, 39 MIN, REST TIME: 32 Hours, 19 min Battery was used for lighting one room during night, with 3 led bulbs hooked to an inverter, so this is why it takes 4 days. In attachment, you have all the data.
It is time to start tests in 3BGS configuration + inverter, with 2 Batteries fully charged, and this depleted batt. I hope in this configuration it would last for more than 36 hours...
I'll be back with more results.

Best regards,
Teodor

Amazing!

Just amazed by the numbers.

ABB has just booked the first thyristor orders for a 10-gigawatt HVDC line in China Ė that is, 10,000,000,000 watts of power in a single installation, with a conversion efficiency beyond 99.6%. This is substantially more than the total energy consumption of Switzerland. Each device has the capacity to conduct 6,250 amperes, and will have blocking capability of 7,200 volts. Under normal operating conditions, a single component will switch more than 20 MW of power.

Revolution Green.

Interesting advance.

Called HyMag, the invention can benefit virtually any technology that draws power from electric motors or generates power from generators. The former includes battery-powered equipment and devices, such as power tools, wheelchairs, golf carts and electric and hybrid vehicles. The latter includes standby power for business and offshore wind turbines.
When designed properly, the gain in the magnetís usable flux density ranges from 10 to 30 percent, depending on the application and working temperatures, said HyMagís inventors, Argonneís Kaizhong Gao and Yuepeng Zhang.
ďThis additional efficiency will translate into either more energy produced or you will have less loss,Ē said Gao, group leader of Nanomaterials, Devices, and Systems at Argonne.
HyMag could especially benefit a weight-sensitive application, such as wind turbines, because the technologyís higher efficiency could lead to downsized structures. Stronger magnets would, for example, make it possible to reduce the amount of weight-bearing and support materials of the outer casings that sit atop direct-drive wind turbines. The outer casings account for more than half the weight of a 100Ė to 130-ton wind tower. Smaller casings could be designed into taller towers, allowing the turbines to access stronger winds.

Tesla motor.

Efficiency.

One of those things has to do with the motor design. According to Munro, the Model 3ís motivator takes advantage of Halbach arrays, which produces a stronger-than-normal field on one side of the magnet while reducing the other side to near zero. Itís pretty technical, but the final result is, compared with motors in competitors such as the Chevy Bolt and BMW i3 (vehicles Munro has also completed teardowns of), the unit is smaller, lighter, more powerful, and more efficient. To boot, itís also cheaper.

Honda.

Iíve just been looking at a cut-away pic of a Honda hybrid motor.
It looks to me as if they are using oblong section wire for the windings.
I presume this is to produce a really compact winding which would give
a more concentrated field and an overall smaller motor.

What do your last several posts have to do with this 3 Battery discussion?

Ignore.

Aaron, either read and learn or ignore.
Down on the farm we use SLAís to maintain blood samples whilst in
transit. Each battery is logged and recharged. Maximum number of
uses is 5, then they are scrapped. If theyíre allowed to go below 11.8v
theyíre also out.
Iíve been interested in this topic for more than 10 years now and am
asking-has there been any progress?
Thyristors are brilliant bits of kit and enable the designer to do what
was once almost unimaginable.
Auto makers are using cutting edge technology in motor design and
smaller,cheaper and more efficient magnets are an important part.
Auto makers and phone makers are all up there when it comes to
battery management systems. I picked up an old phone my son had
ceased using,at least 5 years ago-and its still on that original batttery.
As far as my own switching system goes I soon found out that normal
relays were robbing my battery, SSRís did heat under higher loads as
theyíre never100% switched on and the Arduino was far too greedy.
I ended up deciding that 30amp bistable EMRís were the solution,they
just need a tickle and thatís all, no more wasted juice or heating.
I find it rather sad that quite a few guys are getting egged on to spend
their hard earned,and time, building inefficient,inappropriate systems
and ruining batteries to boot.

Results from 3BGS Inverter test

Finally, i can present my results from 3BGS inverter test...
But first, let me remind you my setup: 3 x 40 Amp Deep Cycle bats , a HQ 300 watt inverter (low voltage limit = 9,6 volt, idle current draw - 200 mA), and the load - 3 Led Bulbs, with a 2,070 Amp current draw. The load was used only at night, for a real day-by-day use.
Total Run was 37 Hours, 07 min, Rest time was 87 hours.

2 times 18h39m = 37h18m. Very close to 37h07m in the second test.

According to those numbers, my 3BGS inverter setup was nothing special, so using the batteries in 3BGS configuration or just hooking all batteries in parallel, would have the same result.
Resting time helped batteries to recover some energy, that is for sure.
It was a long test, because all reading was manually made, but I enjoy it.
Anyway, I wanted to share my result with you all.
It is time to test something different, this one was a bit disappointing...

L.E.
@Bi, I see your post now. I didn't manage to make a single post, because I can't upload all pictures together.
Yes, The results are very similar, so short say: no gain, nothing special using only the inverter, at least for my setup. Maybe somebody with bigger Trojan batteries can tell us more...

Best Regards.

3BGS inverter tests

Hi axxelxavier,
What was your circuit setup and did you rotate the batteries?
Thanks,

But first, let me remind you my setup: 3 x 40 Amp Deep Cycle bats , a HQ 300 watt inverter (low voltage limit = 9,6 volt, idle current draw - 200 mA), and the load - 3 Led Bulbs, with a 2,070 Amp current draw. The load was used only at night, for a real day-by-day use.
Total Run was 37 Hours, 07 min, Rest time was 87 hours.
@Alex, above are my setup info. I did not use a booster, I wasn't necessary, because my inverter have a very low voltage limit and also because the booster add some loses in system.
Yes, batteries was rotated. If you look at the pictures, number of the batteries (upper left of the image) differ from image to image.
In fact, each images represent the stage of battery rotations.
All data was inserted in excel for precis calculation, and, of course, for the graphic representations.
First battery setup was the longest one - 13 hour 47 min, followed by the third rotation - 7 Hours, 44 min.
In the end, because the cycle time was so short (@ 30 min), I decided to drain conventionally the power left in battery 1 and 2. It was @ 30 min for each battery.
Best regards,
Teodor

Boost Module

I keep saying the same things over and over, and nobody listens. I have done the EXACT experiment you just tried dozens of times.

The boost module has a PURPOSE. It raises the voltage coming out of the inverter to 2.5 volts OR MORE over the standing voltage of the 3rd battery. This is NECESSARY for proper charging. Without it, you will never see success. Never. Not ever. None. Zip. Zilch. Nada. As I have said dozens of times before.

As a matter of interest: Bob French lived in a small house with a solar system and ran a 3 Battery/ Inverter (solar) system for MONTHS (before he moved to Mexico) as his ONLY source if power. He could give you a real long term evaluation of the PRACTICAL uses and APPLICATION of such a system. Bob ran an inverter BETWEEN the output of the solar system and his batteries as they were charging, and then another inverter off the batteries themselves once charged. It nearly DOUBLED the amount of power (in terms of hours of actual USE) he got out of the system in a day. Previous to setting it up that way he would run out of power. After setting it up that way he never did. At least not as long as there was SUN. How do you get the output from your solar charger to be high enough to both run the inverter AND charge the batteries? You use a BOOST module to up the output voltage to give you the potential difference necessary to run the inverter, just like the 3 battery system. Which is why I brought this up in the first place.

Boost module.

Running an inverter between the positives you are hitting battery 3 with 12 volts to begin with, which is your potential difference, but as the primary batteries go down and battery 3 charges, your potential difference drops below the standing voltage of battery 3. That's an incredibly costly way to try and charge battery 3, and your results will reflect that. The purpose of the boost module is to maintain the input voltage hitting battery 3 at 14.5 volts or HIGHER so that it is ALWAYS getting hit with a higher voltage than its standing voltage. Your results will reflect THAT as well.

Problem is that differential voltage is @14,5 volt in the beginning, and it's dropping to almost 9 volt in the end, so I don't think a normal booster would work for my 12 volt load.
It should be easier if my load voltage is on 24 volts, but my inverter is working on 12 volts... I will try later the modified motor setup on 24 volts, but after I will find a way to cut the big noise.
So, any suggestion? I want to try again with the inverter and booster, but what setup to choose? 3BGS with booster (I am not quite sure, though, if it will work, because of the big voltage in the beginning, or the setup with 2 batteries, who need booster to work?
Which should be the most efficient?
Best regards,
Teodor

Not sure what kind of inverter you have, most of the ones I have used over the years can handle up 15-16 volts then automatically shuts off around 10-10.5 volts. Most of the boost modules allow you to adjust the voltage, so you could adjust it so ithe initial differential doesn't exceed your inverter's upper limit.
