Howdy Gurugi,

That doesn't look like a circuit to me.  That looks like a schematic.  Just a pretty picture.  Electrons do not flow in a schematic.  Schematics do not produce Back EMF.  You should take a picture of the circuit and post it...

Hi Guruji,


Yes, IMHO, your circuit schematic is good.
Here is the circuit schematic I used for my Bedini's SSG motors energizers.

The R1 and R2 resistors may vary...

(http://freenrg.info/Bedini/Replications/Bedini_SSG_init.GIF)

The neon bulb is not indispensable is you always connect the "battery to be charged".

My respects to Z-monkey.

Best

hi guruji

first i must say that my old friend NerzhDishual has built this circuit and i haven't, so his experience will always be more 'fruitful' than mine on this question

i have used a similar coil switching circuit (not with a motor) and so perhaps i can make a few comments which you might find helpful

i assume both batteries are 12V AND the motor can run continuously whilst the circuit is connected to the drive battery?

you say you're not getting B-Emf - what measurements make you think you're not?

can you confirm that the 2N3055 is switching current on & off through the  'black' coil? how do you measure this? meter or scope?

check your 2N3055 is not showing low resistance (few ohms or 10s of ohms) between collector & emitter (disconnect from circuit first)

if you're using a scope
=======================
connect a neon across collector & emitter of 2N3055 (as NerzhDishual shows in his schematic/circuit), then disconnect the 'battery to be charged' and run the wheel & circuit

you should see positive spikes on top of the left-hand edge of the 'square' pulses at the junction between the 'black' coil and the collector of the 2N3055 - you may also see the Neon glow

if you're not even seeing 'square' pulses of 12V or near then this might explain why you're not getting B-Emf - current is not being switched on & off through the coil - therefore no B-Emf

if you don't have a scope
=========================
try replacing the 'battery to be charged' with a 2K resistor and replace the 1N4007 with an LED and run the wheel & circuit

does the LED light?

reverse the LED and run the wheel & circuit - does the LED light?

if the LED lights in both connections then you're getting switching AND B-EMF

if the LED lights in only one connection then you may be getting switching but no B-Emf (or the transistor is blown!)

if the LED doesn't light in any connection then you're not getting switching - so you won't get B-Emf!


if you're not getting switching you could try swapping the leads coming from the 'red' coil & retry the tests i've just mentioned (or again, the transistor may be blown)

let us know what the results are from these tests

good luck
sandy

Thanks Sandy for your help yes I will do those tests that you told me.
Hi Nerzhdishual that schematic is nearly the same as I posted only a neon included?
Does a neon makes that difference to charge batteries?
Thanks guys very appreciated.

@Guruji

This schematic is the very one of the J. BEDINI SSG 'energiser'.
It is just redrawn from J BEDINI (with and added potentiometer).
It is not from me. I guess I found it in this forum.
I do not remember where...

The neon bulb has no effect on the charging process.
It is only here for protecting the transistor when/if the charging bat
is disconnected. It only glows when this bat is disconnected and could
be an usefull indicator of the functioning of the 'energisers'.

So if I disconnect the charging battery with that schematic of mine the transistor would blow up?
Thanks Nerzhdishual

not necessarily - the neon is there as protection just in case - it would depend on how large the spikes are, how long you operated the circuit without the battery to be charged, the voltage rating of the actual transistor used, etc

but since there is a good chance of damaging the transistor without a charging battery connected it is best to have the neon connected

PS if you do the LED tests above, it's a good idea to check the LED first - i'm sure you would do this anyway!

all the best

Hi Sandy I did those tests and yes the led lit up on both sides even when turned the other way.
Is there a way to measure the Bemf now?I will do the neon now.
Nerzhdishual it's better to use 10ohm resistor than 680ohm with the variable resistor?
Thanks guys.
Andrew

hi Andrew

if you are getting Bemf with the circuit as you showed above, then it will be difficult to see as voltage on a scope and difficult to measure as current with a meter:

the Bemf collecting diode (1N4007?) will limit the voltage across itself to around 0.6V - so if you do have a scope & can turn the Y gain up to say 0.1V/div you may see a short pulse, around this voltage, measured across the diode every time a magnet on the wheel passes the coils

although the Bemf pulse voltage has been limited to around 0.6V, the current is not limited by the diode so the Bemf current will flow into the battery - and the impedance of the battery to the pulse will limit the current

it will be difficult to measure the Bemf current with a meter because it is unlikely that a regular meter will give a true reading of such a pulsed waveform

if you have a scope you could try adding a small-valued resistor (measured) in series with the Bemf diode & 'battery to charge' - with a 'data-logging' type scope it is possible to get the average of the pulsed voltage across the series resistor and then work out the average current thro' the resistor - hence find the Bemf current

another way would be to replace the 'battery to charge' with a large value capacitor (the largest you can get at a rated voltage greater than say 40V - connect a variable resistor in parallel with the capacitor

what value of the resistor just keeps the voltage across the capacitor at around 12V?

this will give you an indication of the amount of load that the Bemf circuit can drive - 12V / (resistor value) will give you the average Bemf current into the resistor load and then you can work out the power (& energy for a length of time)

remember that if you use a polarised (eg electrolytic) capacitor then the +ve terminal must go to the Bemf diode shown in your schematic/circuit  and the -ve terminal to +ve voltage rail (just like the battery connection)

hope this helps!

HI Sandy thanks for your response.
How long does it take to charge a 12v battery with this pulse motor?Example I have a car battery showing 10v would this take long to be charged by this motor?
Does anyone have a time rate about charging of these motors?.
Thanks.

well, this is going to be dependent on the Bemf of your particular setup - and the AmpHour rating of the 12V battery you're trying to charge

i guess this brings us back to your initial request re: measuring the Bemf of your rig - how long would the power provided by your measured Bemf take to supply at least the energy equivalent to the AH rating of the battery? once you've measured your average Bemf current you can do the math to find the time

Also, since presumably this design is supposed to have some overunity performance, is there any power gain achieved in the pulsed-recharging by the motor which means you supply less energy than a full recharge requires? someone with experience of the the Bedini SSG will have to help you out here

all the best

Today I included a neon to the circuit but when disconnecting the charging battery the neon did not light up why is this?
MAybe I did not put the right neon?or there is not much bemf to light up?
Sorry for to many questions but I am new to electronics.
Thanks guys.

yes, it could be that the neon doesn't glow until a higher voltage - or that the peak Bemf voltage is not high enough to make the neon glow

as NerzhDishual said earlier, the neon is only there as a protection for the 2N3055 - in case the Bemf voltage ever gets too high (eg. possibly when battery disconnected, or if 1N4007 diode fails, etc)

it's like a seat-belt in a car/auto - you hope it won't be necessary - on any journey - but you always wear it just in case

have you tried replacing the charging battery with a capacitor yet?  the voltage across the capacitor (without any resistor) will show you the peak voltage of your Bemf

try an electrolytic capacitor, say 200uF 40V or near, connected same polarity as the battery to be charged - you could probably leave a meter connected to the capacitor leads while you run the motor (use, say,100V range first and adust if necessary)

all the best

@Guruji

Nul-Point (Dr Ringwood) is far best that me in all these kind of electronics matters (and in Bass playing, BTW) . He his, probably, also the future author of one very book about Capacitors, Condos, Heroic Fantasy, 'OU' and Romanticism!
(Private Joke    ;D ;D ;D

With this small SSG Bedini 'motor' made from  16 (=8*2) very weak ferrite magnets, and a old computer (double) disk 'fed' with a 7.2 volts bat, I was (and still are, I hope) able to (quickly) charge up a 1000uf cap at about 50-60 volts. This is not claimed to be OU!

(http://freenrg.info/Bedini/Replications/SSG3_Small.jpg)


May I suggest you to consult one of my previous posts about Bedini SSG tests:
