Bedini SG

[ABCStore]

Two questions:

1. What is the recipe for finding sweet spot? I can't measure RPMs but I do have a good oscilloscope. To re-phrase, what should I look for on the scope and ammeter?

2. What are the maximum voltages tractor and car batteries should be charged to? What's the ballpark?

Thanks,
ABC

Make sure your meter is on the right setting and your probes are in the right plugs.

I made the mistake of not breaking the circuit to connect amp meter.

thanx ren. can u tell i'm newbie

Hi,

In the original SSG you can see that there is only one battery in the setup.
That allowed as you said the 9V battery to run for over 5 days, which extends the battery run time as you have found. The ideal is to have the setup be a self runner, for the way that Bedini / Rick have gone about that is the "School Boy" setup by Rick, or by Bedini using the Cole setup that triggers the transistor in very fine order. (PESwiki has the diagram of the "School Boy" setup by Rick, Bedini's setup using Cole trigger is found on his page. )

If you want a long lasting battery, then feeding the charge back to primary should not be a problem to extend the battery just a bit ( say you are wanting to run a small fan for a long duration ) .

If you were targeting a self runner then Both Bedini / Rick would steer you away from this, Rick would point you to his method of using a switch on the rotor to disconnect the primary for a short duration and dump a cap back to primary battery. I have not had a self runner myself, but it seems like a very fun thing to attempt. I believe I am getting very close with my Bedini / Newman Hybrid of the Daftman's design. But have not proved it yet to myself.

In everyday life in our cars we have a battery that is being fed voltage from the alternator. The battery is getting more energy than it is supplying to the rest of the system, thus it always stays charged. I have thought about this and have used this by putting solar cells on the source battery of my Bedini, thus it can continue and run as long as there is sunshine.

cheers, thermart, didnt know about the self runner,gonna check it out,bill

Hall Effect Trigger for Bedini Circuits?

If I use a Hall Effect device for the trigger then I do not need the trigger wire at all, correct?

Anyone have any luck with a particular Hall Effect sensor?

A Mouser part number would be great.....

Have a most excellent day...

yes you are right, but I did not leave it in parrallel, i cut the old resistor out while running. leaving 100ohm and a new pot. its now running quite fast and drawing 01.0 from 12v 3.3ah on multimeter, meter set to 200 aca. this info I do not understand as yet. its coming slowly. crap meter that dosent read below 1volt, but its got one of those loops to read current. need to change fuse in my other cheap multimeter.

what is the correct method to test current? As i got a small 5amp dial i want to connect. i dont know where to connect it. I dont want to blow my last meter.

please help. its now spinning without purpus it seems. and i going by touch, smell, SOUND that now no use

@tjnlsn255:
Thicker wire would have more current which you gonna have to fight against with a larger resistor. There's more to it but I would stay with AWG23 or even AWG26 for a trigger.
All is IMHO

I did not twist my wires but the different sized wires is a real pain in any case.....

What would happen if we use #20 for the trigger as well.... just a thought....

Be happy....

In my setup I did twist all 5 wires together but is there a real advantage of doing so? It is also a pain to work with because the trigger wire is thinner and stretches more than the other 4.

Charging the primary battery.

hi, theremart, having been running all my bedini motors off 1 battery for the last year,still waiting for a 2nd one.theres no advantge, but chrge through a rectifier,going to the source battery seems to make it run longer,as if charge in
been taken in or possibly helping to run motor what do you think happens ,cheers bill

Hello ren

thanx 4 tip. got those ready to go on today. will have to find the bulb first. i salvage a few of those resistors, 100 ohm 1w. i bridged it over the boiling resistor while running and it spun faster and quieter.

any ideas where to salvage bulb

Rusl

Paralleling (or bridging as you put it) is not ideal in this instance. It will increase the resistors wattage rating, but it will decrease its overall resistance. Also I have noted that it doesnt always give the same result as a single resistor of the same value, others have noted that too. Overall, you are best to remove the smoked resistor, as its resistance rating is most likely comprimised anyway.

Any small DC globe, say from an automotive application, could be used, but it should be proportional to the input current somewhat. No use using a 50 watt globe on an oscillator that draws 100ma. The "grain of wheat" bulb is the one suggested for the small builds, these are usually rated @ 50 or 100ma. You could find them on ebay or at your local electronics shop. LED's arent suitable, but that is about the size of the GOW bulb mentioned above.

According to Bedini, this cannot be done as you cannot charge primary battery at the same time as discharging to target.

I have been testing out the design of 4christonly, which claims that you can do this, Plego had some success in this means, but I am still in reasearch stage of this.

hi again Sethiroth

i just click your picture and it took me to invertibrates youtube site.
If you are he or he you, then Id like to say that those videos helped an awful lot too in understanding this circuit. Great tutorial and descriptive, though less friendly(User), than a simple drawing.

Probably it was the first reference to it I remember viewing.

Again thanx
