Hi Dave,

thanks for sharing the results of your hard work. I've been quietly working in the background on my version of a generator in trying to get similar results. Improving but not there yet.
I've been playing with the number of magnets (neos) and orientation, for instance all N on one rotor and S on the other, or N-S arrangements, from 2 to 8 magnets per rotor, gap, closed loop, open loop (rotors are magnetically conductive iron) and a bunch of other things. Attached is a picture. The housing is big compared to the rotor as I salvaged it from a muller type setup.

I was wondering if you could answer a few questions:

It seems to me you have magnets on one side of the coil only, correct?

Neos or ceramic?

NSNSNS arrangement?

What kind of open voltage do you get when the coil is unloaded?

thanks,
Mario

hi mario. nice work.have the air gaps been optimized. it looks like closer might be better.

cheers.

Hi Voltan, thanks. Have you ever played with a neo that close to a core? These neos are 2 cm in diameter and 1 cm thick. the closest I went is a 4 mm gap. The lock is so strong that the razor motor can't start and I have to help by hand!
Closer would probably be too heavy on the bearings and the whole structure I'm afraid.

Mario

point taken. i haven't played with neos that big yet. i have pulled down and rewound a small emax rc motor with small neos in the hub, and it takes a surprising amount of force to separate the motor,after the removal of a circlip on the shaft. powerful stuff.

cheers.

2 Battery Split Positive System

Hey guys,

It's been a while, but worth it. Below I have drawings of my original modified version of Dave's 3BGS with the Boost Module that I'm calling the 2BSPS (2 Battery Split Positive System, which I like because it has BS in the middle of it). Next, I have a drawing of a version that I will be trying this weekend (ran out of time last weekend) that is essentially a doubled system except the lower part gets the switching for free. If we set up more brush pairs on the commutator, they would get their switching for free, too.

My latest tests results are for my original 2BSPS which I had set up with the commutator. I made the commutator by simply cutting the wires off the commutator in another motor (but didn't remove anything) and soldering wires from one face on the commutator to the face opposite it, so all it does is chop the current for the lower system. What I found is that the rotor and winding, though not connected, do act as a small flywheel and increase performance. So, I will incorporate a flywheel from now on.

Results, all tests for 10 minutes with at least an hour rest afterwards before measuring.

Start B1- 12.30V B2- 12.24V
Test run 1 B1- 12.37V B2- 12.51V
Test run 2 B1- 12.38V B2- 12.57V
Test run 3 B1- 12.24V B2- 12.56V
Test run 4 B1- 12.20V B2- 12.53V
Test run 5 B1- 12.22V B2- 12.58V
Test run 6 B1- 12.29V B2- 12.59V

Tests runs 3 and 4 had bad results because I don't have the motor and commutator secured well and I have been doing these test while stopped in my truck (18 wheeler). So the vibration of traveling jars them out of alignment, causing excess drag. I ordered some motors with actual bearings on each end (instead of the bushings in these) and will set up a better test unit.

But the bad runs do demonstrate that even if you were to draw off some energy from the batteries, taking them to a lower level, the system will recover.

I'll keep you posted.

Bob

2BSPS, doubled pic

Here is a pic of my current test unit. Note that the wires coming out of the lower Boost Module are backwards. I later realized that I needed to run the Positive through the commutator.

Bob, you are hard-core. Doing tests out on the road.
I hope you have a cover for that unit when you get inspected by the DOT. LOL
Looks good.

Another setup

Well, here's the setup that I tried yesterday with fairly good results. I think it's better than the one motor setup, but am still testing. Nothing OU as is, but it works and I haven't attached a generator to it to utilize the mechanical which I also think would be increased if I added a flywheel.

Hi Bob, that's interesting. I've been trying to feed my internal generating coils directly back to supply , but everything heats up.
So have been feeding into a separate battery, and then charging my 2 drive batteries, by running a second little motor with the split positive set up, Charging a 20 volt battery , and running it split with the 2 primaries.
I still lose but , my runs are about 30per. longer.
Also I get ~50 volts dc off my attached generator ,but if I put too big of a load it'll just stall.
I don't think the windings can deliver the right amount of amps.
I'll try using the little motor on negative supply.
Thanks artv

Hell guys,

I've been waiting on parts and not had much to say lately, but...press on. I've tried a few things, but nothing to brag about.

Matt, are you saying to run the neg side motor twice as fast as the pos side motor, or half as fast? I just had them directly attached so far, although I did try setting them out of phase sort of. Because they are 5 pole motors I think there is always overlap in the power windings that are next to each other, so there really isn't an OFF time for the other motor to be ON by itself. Any suggestions for finding a gear setup? I have motors with .125" and 4mm diameter shafts and could get another size if necessary.

Matt, I have a Razor motor that I rewound according to your specifications. It has an 8mm dia. shaft and I have a 16" 8mm shaft, 8mm pillowblock bearings, 8mm couplers, six 3.5" coil spools with .75" cores, many .5" x .75" x .25" neos...everything except steel rotors to replicate Dave's generator. I'm waiting on Dave for more info on what core windings to use and now he's indisposed. I'd like to order magnet wire, but don't know what size or how much a coil will need. Any suggestions? Also, I'm thinking of using two rotors, with the coils in between, and bolts between the rotors that I can adjust to make them exactly parallel and straight. Looks like the rotors will be about 14" in dia. I was thinking of either 1/8" or 3/16" thick steel rotors.

Also, I'd like to find a small motor with an even number of poles (2,4,6,8...16,18,20), something smaller than the Razor motor, that would run on a lot less power for these other experiments using 12Ah motorcycle batteries.

Thanks, everybody, for your kind words and input. Stay tuned...

Bob

Twice as fast.

Of course, Matt,

Got it...then the second motor would pump out the higher voltage for the remainder of the citcuit, cycling into the front end, essentially looping it.

Thanks,

Bob

Single Battery Split Positive System (1BSPS)

Guys,

This works. I'm still trying different things with it. So far, it looses and I'm just using a very small conventional motor. Nothing really to report other than it runs.

Twice as fast.

Matt,

Until I find a gearing mechanism, I'm thinking of using the second motor as a generator, rectify it, and run a Boost Module off it back to the system...somewhere (?). Various possibilities here. Everything wants to see a higher voltage coming to it, so...

simple but interesting scheme bob.i guess both negatives on the booster are connected internally, or on a common rail.

cheers.

1BSPS w/Bedini

Hopefully some parts have come in when I return home tonight.

This week in the truck I tested the 1BSPS w/Bedini setup (attached below) with no great things to report. I didn't really expect anything, I was just surprised that it ran on the Split Positive. That shows me that transistors don't care that there's no "true" negative. We're just running on a difference in potential.

I am going to change it up some and try again with a separate trigger in the energizer and use the 2BSPS w/Bedini setup when I have "extra" time. lol

Stepper Motor SPS Charger

This seems to really work. Preliminary results look like 20 to 1. We'll see. I'm not in front of it at the moment, but I'll give the details of the parts that I used as a starting place. I don't think these parts are critical, but I always like to get something to start with myself.

I got the "Splitting the Positive" terminology from Bedini and Grey. I agree with you, Matt, but I haven't seen many people using a second Positive to "ground" to, so it helps me to explain to people how things can be engineered differently.

I have been using Chrome on this sight with pretty good results.

OK guys, let's get out there and stir up some dust.

Bob

Sorry I have something wrong ,I can't use this site or the OU site all others work, just keep getting warnings telling me to leave powered by LaSuperba
I keep accepting the risk and it keeps asking me if Im sure
There's a big red ad right now tellng me I'm at risk
Keeps wanting me to phone a # to report
It has something to do with the ads I won this I won that
now it won't show me the #

Hi shylo,

Hopefully you are not using windows OS? Too many hacks possible to misdirect, even anti virus companies in cahoots to censor sites now. If using firefox browser, go to tools, add ons and install ad blocker and get rid of pop ups saying you won something.

Best not to use window OS. I use small linux program called puppy linux, version slacko 5.5 here:
Tahrpup CE is Released - Releases - Puppy Linux News
Puppy linux runs in ram and is very fast. Don't even have to install, but run from usb stick on any computer. Works great on my 8 year old laptop. If you have newer laptop try this puppy linux:
Has easier interface and better media player. Tahrpup CE is Released - Releases - Puppy Linux News

Hope this helps,
Chris

Hey Matt go **** yourself if I need sex my wife is more than willing.
Maybe it's you sending this ****.
All I use this box for is to ask questions and maybe learn something.
Funny how it's only this site and OU that are being affected.

Chris Thanks I'm not sure about what system I have ,I do use firefox mozilla

Back to my last post...

The first time that I ran this setup, in 30 minutes the Primary dropped .01V and the Charge battery went up .19V. Then I had to leave, so I left it running. After 7 hours, I stopped it, set those batteries aside to rest till morning, and started another run with other batteries to run over night. Since that first 30 minutes, every other run has been loosing!

I've seen this too many times now and I don't get it. Maybe someone can illucidate.

Below are the two circuits. They run, they charge, but no OU so far.

Using the single battery setup from the above post, I've run numerous tests without much to report except...

Over a 30 minute test, the voltage would drop about .02v, the amps would drop from 450mA to 430mA, BUT the rpm goes up from around 1652 rpm to 1836 rpm! It's freaking me out. The input drops and the rpm goes up.

I tune the setup by running the motor fast, then adjust the pot to a "sweet spot" where the amps increase if I add or subtract resistance on the input. This is the lowest amp draw with the motor rpm high. (This motor seems to run in only one speed range, or it runs down and stops.)

The changes in voltage, mAs, and rpm all happen gradually and steadily over the time of the test.

Dave, In reading this I noticed that the parts list doesn't match the schematic. The list says 100 Ohm and 220 Uf and the drawing says 1000 ohm and 2200Uf.
Thanks
