Hi Bistander,
You have right with over charge lithium chemistry.
After I started to read that thread, I think it's not for me. This is why I insist to build a generator based on Ufopolitics asymmetric style.

Hi vastdragon, and Ufo,
Be careful with 3BGS and Lithium batteries. Lithium batteries require sophisticated cell management (BMS). If run without BMS and on a system where overcharge is possible (maybe unavoidable), disaster is likely. All the 3BGS use lead-acid of which I am aware. Lead-acid is pretty forgiving about charge.
Regards,
bi

My basic rule when I find a new thread is to read first the whole thread before to ask. I don't like people who ask first before reading.
What is your opinion about building a generator base on that drawing? Also, I want to wound coils in bifilar Tesla style.
Best wishes!
Vastdragan

Where I can find more info about "3 Battery Energetic System". I try on google, but no results.
My off-grid system is composed by: 3700Wp PV panels, 5kVA inverter and 24kWh lithium battery from a salvage Nissan Leaf.
Also, I find a picture on internet which I suppose is made by you. I can made this on radial flux or axial flux to use with a wind turbine. What do you think about this?
Kind regards,

I think I find here the thread:
http://www.energeticforum.com/renewa...ng-system.html
And yes, that's my drawing, it is an outrunner bldc that I built from scratch...works beautiful.
On the 3BGS THREAD, You will have to go over the whole thread FIRST!...Please DO NOT start asking questions before getting the MAIN WHOLE IDEA on its SPECIFICS.
Thanks and welcome!

Thank you in advance for answer.
P.S. What happened with your website? From Romania it appear to be expired.
Thanks for following my Asymmetric Machines.
My server at home plus my remote server where I got the site, have been attacked...and will take me a while to restore.
If you want a RELIABLE SYSTEM to self-sustain in winter time, please check the 3 Battery Energetic System...they are good and easy to build-install and run.
Kind regards

I am getting almost triple the performance from the OE motor!! Built around a 1.1ohm winding, I am sure the amperage consumption is better the the normal asym motor here, as for instance, Ufo's Imperial.
there is a Baldor office in the Philadelphia area near me. I would love to show this to someone there!
I remember how Ufo's Imperial motor did around 3400 rpm on 48v, but mine is only a dual brushset, while his is a quad.

Great to see ya around old friend...and kicking...

My old baldor
Well retired now and a little more time to do things. I have a Baldor industrial DC dual brush 20 pole motor I have been working on and now finished. The commutator design featured reusable spade connectors, whose photos I have posted previously on the thread. Boy did they come in handy as I had to rewire the motor several times. I could not fit enough wire by just lowering it a guage or two from the original 19ga size to get 1ohm of copper wire on it. I calculated the area of the pole gap and the area of the wire plus gaps between round wires, but ended up having to apply a 2.0 correction factor to double the amount of wasted space in a wound coil. I looked into first a quad filar, the a 5-filar 28ga wire to give me the same surface area of the original 19 gauge wire, hoping for more current carrying capacity. As I wound it it looked like it was not going to fill the rotor sufficiently by coil 6. I test wound 24 gauge wire hoping to do a bifilar, but I lost the results. Later I perfected a spread sheet to calculate how many strands of wire were going to be used. If I hadnt lost my test result I would have seen I couldn't get enough wire in again. I got to coil 10 and I could then see it wasn't gonna fit again. So tired of making multifilar wire, and having a better estimate of wasted space, I thought 23 gauge would fit, single strand. But again got to coil 10 and thought it wouldn't fit. So then I did the next 6 coils with my old 5-filar 28ga wire that I saved. At coil 16 it sitll didnt look good and changed to single strand 24 gauge and managed to finish. I always wound in pairs of coils, first coil 1 then coil 11 balancing it with the same wire and wire lay on the coils. Here is my coil winding work sheet and a picture of the rotor.
Assembled
I explored adding an additional brush set to try to tap the coil disconnect BEMF spark energy (red and green wires), but they did not work and just dragged some emf energy out of the system instead. I should probably play with the timing as it is assemble to run in the normal mode.
so pretty much as usual with Ufo Asym motors looks to perform astoundingly better than standard Edison style motors. I have a standard Baldor motor of the same type and hooked them all up and tested both and here is my first results:
Using 24 volts
Standard Baldor rpm 400
Asym Baldor rpm 1400
Now my Baldor I built it to have a 1.1 ohm resistance per coil, instead of the standard 1.0 recommended by Ufo, as I was worried about how hot some of my motors were in the past. But I have checked on the motor magnets, and they seem to hold their magnetism until 400 deg Celsius, or around 700 deg F. So it seems standard magnets will hold and it is no big deal for motors to run at hot to the touch temps, with good wiring and bearings.Last edited by sampojo; 03-12-2018, 05:56 AM.

Commutator R&I

There are several posts on this thread dedicated to comm removal and re-installation.
Basically the main issue here is that you can NOT push commutator outwards by pressing on any of its outer elements base area (bottom)...If you do it so, it will create an uneven force and will definitively brake it.
You must reach its center bottom ring right next to shaft to make an even push out of armature, and so depending on the size, you could use one of the "Y" type crow bars.
Normally this type of Y Crow bars are used in automotive to remove plastic clips off door panels or any other fastener which have a flat head...so, again, depending on your comm-shaft diameter size, you will need that specific size tool.
And so, you will need TWO of them, one just to be used as the base and the other to eject commutator from bottom ring base, resting on the first one.
It is -even this way- a very careful operation, since commutators are made of bakelite which is very brittle.
Sometimes you must remove (cut off) the windings in order to allow full access to the bottom comm ring.
Regards and good luck.

How to mount commutators
Hello UFO,

Yes i remember that entry but never equated it to the machines
as shown in this post. The "WITCH" video meant little to me at the time
but now that I had time to see and read the entire video, I am realizing
more.
I am just starting to grasp the UFO message after doing the Matt Jones
motor and seeing success. I needed a simple task to help me get my foot
in the door. It is becoming so clear. This UFO video is a must, take the time
to read and go over the material in it. Otherwise you missed the starting
gun firing and you will not understand much of the other video's.
I see now that these concepts are all over the standard COP of .25 so
it should be easy to go OU.
The magic spell of lies, deceit and malice are melting away like butter.
UFO is willing to take it on the chin I see

That is, once I figure out what to hook it to.
Lot's of testing first though.
What an interesting project!! Thank you Mr. UFOPolitics!
GlenWV
My pleasure Glen, looking forward to see that beautiful monster running...
Make sure to check continuity-resistance in each coil (or coils groups, if that's the case) contact between comm elements plus alignment.
Also check your stator's magnet polarity orientation (N-S-N-S), related to your desired rotation sense versus the feeding (Input) brushes positioning to fire each coil group.
An All North Wound Machine of that kind is unique on its class -at least on this Forum-...and it should run superb, when synchronized-tuned with high precision, thing I know you would do an excellent job on...!

Please don't worry about my accent...I know it is terrible!, and believe me...I can make it even worst...so that was kind of "refined"...
Originally posted by Dwane View PostI picked up this Baldor armature for another project - now shelved - a couple of years ago. I have no stator for it. It was rescued from a burnt out motor. It has 28 windings and 56 commutator sections, so I am pleased to see the wiring for this configuration has been demonstrated. It is a heavy cow! It might originally been 3HP.at 90 volts or180 volts. I got it from my local motor winders who were given it as a repair job that did not proceed.
I believe if you had the model number or serial number of motor it would make the part (comm) search much easier.
Originally posted by Dwane View PostWhat has really taken my fancy is your fibre glass stator. Do you think that I would be able to run this armature as you have shown in your videos with a fibre glass stator. I am hoping to utilise it similarly to your combination drive generator page 96.
Originally posted by Dwane View PostAlso, when rewinding this as asymetric, would I use the same guage of wire that is already on the armature?
Many thanks
Dwane
A heavy gauge wire (lesser turns per Coil) would have low resistance, therefore, amps would be higher, with lower voltage application, (like Automotive Motors) torque would be higher, since magnetic field would be very strong.
A fine wire (many turns per coil) would require higher voltage with lesser amps to build the required field to perform properly with such heavy armature.
