3 Battery Generating System

[wantomake]

2018 and beyond?

To All,

I do understand the frustrations of non participation of so many good minds to replicate here. Matthew and Dave have poured out all the details to get this system on your bench to start your own journey to freedom to whatever you want with it.

I'm a former teacher and missionary church builder for Japan. I've seen non participation up close and very personal. But I knew if one person would follow then that one could change five and five would change twenty five. That's the mission here to show/present to the audience and let that one person take it from there. I did get one and two to follow and left the building to them. In Japan I'm sure. We go every year or so to see what one has grown into. Amazing.

It's my last month on this thread. Either others will continue here or not.

I will be so busy with this 3BGS on a larger scale next year.

Matthew and Dave, I've found my five......

Shhhhhhhhhh

Don’t tell anybody this works. They might actually build it. THEN where will we be?

Balancing

Connected second booster today into the setup to see what happens.

The balancing involved was a pain but is doable. I've learned that there's a way to keep the primaries charged and maintain voltage in the #3 charging battery at same time. But, more than running the lights in my shop, it's a great learning system.

I appreciate the effort from Matthew and Dave to post all this information and leave it here for any to follow and replicate.

2nd boost converter

Got the 2nd boost converter yesterday and plan to install it today.

It takes time and understanding to balance this system to do work and loop back on itself. I care nothing for the COP of this unit or OU.

My plan and/or goal is to simply have a back up if the grid fails during storms, maintenance (transformers), etc.

At this point I'm studying to see which component bares the stress of this system. Which component actually will burn up first. Motor, generator, boosters, inverter, or the batteries. So far the booster has smoked twice now but they are only $12 each. Only two in last two years which is low count for me. But still that takes time to get new ones in. Overcharging the battery bank is largest failure thus far.

Balance as one correspondent has instructed my curious mind,

Generator

EVERY coil will speed up under load at the correct frequency. If yours does NOT, here are your options:
1. Turn rotor at higher rpm
2. More magnets on the rotor
3. Longer wires on coil to increase capacitance
4. Coils with many strands of wire wound in parallel and connected in series.

My 10 1/2 inch rotor with six 2” Neo Magnets on it needs to rotate at 2800 rpm to get my coils to speed up under load. The coils are made of three strands of # 23 each 800 feet long. Those were my “original” coils that sped up under load.

My current coils use 12 strands of #23 each 253 feet long. Strands are connected in series so I end up with only 3 wires coming off the coil. It speeds up at a much lower rpm. Matt says he has a formula that works for this. I don’t. I just know what works on my machine.

Mmm

I know that Matt's modified motor is in the heart of this system if you want to do serious work. But even without it the system is still profitable.
Dave used to say all batteries should be topped off. That was little difficult for me to sustain a good balance, (with my kind of batteries) and not have the 3rd battery overcharged. But when I first drained just a little the third battery(-ies), i was able to sustain long runs like 2, 3 hours without anything moving up or down. I mean 0,01 or 0,02volt doesn't mean much. And always, if prime lost ,01 or ,02, the third combo battery(-ies) would have gain that, the same amount. All measured at least 4 hours later. Used to use two boosters as in Matt's schematics for that.
As far as I remember Mathew never gave specs for generator in public, only for motor. I think Dave said Mat would do that only to some few people they trusted. Is this, that kind of Matt generator that you use, or is it Matt's modified motor put as a generator?

Liber63,
I'm only using Matt modified motor as generator. I don't have the finances or knowledge to build the monster Dave has built. He has a lenz free generator which I believe he gave instructions here and there to build it. I've learned if you increase generator size, you must increase prime mover size, battery size, booster size, etc. I'm not ready for all that. It's about balance.

But I've not seen Matt's generator details yet.

PS: Think about it. All they've freely given us already is enough to power anything you want. I'm not greedy so the system I have is enough to build larger and power more. Just balance. It's all documented here FOR FREE !!!

Main component

yes, my friend. I have replicated it with a 400watt inverter and small loads as i only used (a lot of)car batteries, and yes it worked as advertised! Definitely, am going to try Matt's modmotor with a flywheel and some sort of generator i haven't yet decide, but for now i'm putting together a small solar system with deep cycle batteries together with the system above, as Bobfrench did. Small system altogether but with great advantage. Don't have notes as I experimented almost a year ago. But its pretty straightforward for people like me if they only have the patience to tune it. I honor Matt and Dave.

Liber63,
Not literally "notes" but your experience and ideas with this build.

The "main" piece of this machine is the modified Matt motor. I have medium size as a generator. The prime mover is the smallest size razor motor. His motor with the 3BGS is the combination that works. Both motor/generator are wound to Matthews specs. My battery bank(marine batteries) for my solar system is connected in this setup. It's a small solar setup but powers my shop. I've a switch to charge the bank with solar until I start running test. Then switch off solar and run test.

It's simple setup for me but is good starting place to learn.

Snowed in today, early for the south, but will just drink coffee and study.

Schematics

@ wantomake.
Here are official schematics from 1Dave, 2Matt and 1Bobfrench, which is basic all the same way.

Liber63,
Thanks. I went with the first schematic. But will add more as parts arrive.

Are you replicating? There's nobody to discuss notes with that has a work in progress.

Matt or Dave,
Is this the schematic to connect the boost converter?

I have been powering the prime mover with the booster. Then charging High side with voltage from generator. Just got replacement and want to use it correctly and safely.

Possible boost circuit.pdf

[BroMikey]

If you want to keep your boosters try this.

The heat here gets to be about 110 degrees so anything over
2 watts warms up and the semiconductors start stalling right
away if you run a couple of amps without cooling.

I also bought 10X step down tiny's for a $1 each so i can feed my
meter perfect numbers. Don't forget to you need to move the adjusting
screw very little to peg the nettle.

The fan runs about 6v on a 12v source and at 14.5v about the same, if
you go up to a 26v source the voltage is somewhere around 10v
depending on your fan. The fan runs forever at 6v, the whole thing
takes about 65ma for the fan.

The switch puts the tiny amp gauge in and out of the circuit for
times of adjustment. This can also be used as a power supply that
is adjustable for a very low cost.

Bromikey,
I do understand it takes time for an "idea" to develop into a viable build for anyone. We all have short patience sometimes. In college it was often disheartening to hear the lack of education in the younger generation sitting around the room. In highschool I was a low GPA score. But mine was higher than the upcoming generation with a lack of good educational schools these days.

update

Just a update on the 3BGS build.

Did finish the (smallest my1016 razor) modified Matt motor rewind. Using 24 awg trifilar connected parallel 100 feet long. 40,30,30 turns on each side of rotor. Ohms across each coil was at .04.

Pulls 0.7 +- amps without load. With generator(larger size mod. Matt motor) attached with couplings, the amp draw is 2.25. Heat is low after extended runs.
The couplings acts as small decent flywheel. A Drok dc to dc converter powers the prime mover to 18~20 volts. Haven't recorded rpm's yet.

All this information to replicate is already posted here and other threads.

I smoked first Drok converter by overcharging #3 and inverter batteries.

Comment please if you are building.

I agree

Just want to say how much i appreciate the knowledge turion dave and and matt have shared. These special gentlemen should be thanked a lot more than they have .

Ron,
True. But there's hardly any true builders that I've seen. I'm still trying to get all the parts together for good long runs.

I had a power outage last week. A local transformer sounded like a bomb that woke up our sleepy country area. We ran lights and laptops until power was restored. But thats only a few watts for 2 hours only.

How is your setup doing?
