there is no way to effectively measure the output amps (its interesting to note the relationships however inaccurate an analogue gauge may be) but an analogue panel meter is reasonably accurate for the input current.

A little something to think about

Hi Everyone,


Heres a little clip I made of my new SSG with a piece of steel behind the core to demonstrate the motor picking up speed and dropping in amperage that I stated in an earlier post.Enjoy and dont mind the radiant dog food can as it was only to demonstrate the sound more clearly of the motor speeding up .

p.s.oops! guess it would help to put the link

Great demo ... but now questions

And again GREAT DEMO.

My only question?? Can you put a load on your system ( mechanical or electrical ) and with the steel redirecting flux paths ... do your get extra power?

Stay haven't work out the bugs

I don't know guys i tried almost everything to get this motor to running. I might think i found the problem when i test my coil by hand rotating it i mesured it with ac meter i was reading 0.6 .7v do i need more to get the tranisistor to switch. Also i when get connected everything the primary battery has less voltage .347v than secondary batter 7.56v. Is suppose to be doing that, next i going to try start it up with a power drill. You guy please tell me if that is a good idea

transistor is tip 3055
coil are wind 630 turns roughly
battery 1.3ah 12v

Hi Dodeca,

If you notice I am powering a fan in that clip, But as far as putting a REAL load on an SSG I personally dont think it can be done unless built very BIG.I'm only trying to figure out the best energy recovery method with regard to the SSG.It takes time to READ BETWEEN THE LINES on what is best method by experimenting.I have now figured out the particular POPPING sound that I believe is a huge TIP for anyone experimenting with the SSG to be looking for.To answer your question yes I get more torque for less amps but that comes at a price of less recovery to the secondary battery.I personally would like to explore that happy little popping sound further.Hope this helps answer your question.Oh,by the way have I mentioned that I've been accused on more than one occassion of thinking way out of the box lol.

Hi,

It took me about 2 weeks to get my first one up, that was because I had the wrong value of resistor But, it would probably help if you would upload a picture of your setup, and give us input voltage, and the parts you are using to construct your SSG.

The type of magnets you are using and the input voltage are big factors..

Make sure your magnets are all "north" outward. Also flip your transistor wires, often they are switched.

good tips from mart.

the polarity of the windings is important so double check that (and make sure the ends are nice and clean, no insulation).

close your air gap down as much as you can.

600 plus turns is more than enough, try a 10 ohm resistor to get it running. Not sure what you mean by the primary has less voltage, do you mean it drops when you connect it? IF so you transistor may be fried or you have an incorrect connection somewhere, it shouldnt draw anything on connection.

If you look at the pic i post i first connected everything than i test the primary batteries, and voltage drop to 1.76. The weird part maybe the source of my problem the secondary battery is reading 8.89. If keeping the two battery connect longer the primary will still be droping to .378, and so would the secondary down to 7.41. I took extra picture for u guys if u can spot something i can recognize which the source of the problem.

Going back to drawing board

I using your normal cermic magnet that i buy at lowe's home department store. The dimension are 7/8" x 1-7/8" x 3/8" you can see them on the pic i post there 8 magnets on the rotor. I right now using a 480 resistor going to change it to a 10 resistor probably go to wtf if that was the whole entire problem lol

[gmeat]

Hi Runningrage,

I think you may have your magnets to close together.Try using 4 on your wheel.I'm pretty sure that will hinder the function of the SSG as the coil needs more space to charge and discharge,Someone correct me if I'm wrong as I'm just trying to help out.Hope this helps,Good luck.

hmmm... I agree with gary... the magnets look very close...

though I am a little worreid about the condition of your batteries. It is probably self resonating when you hook the battery up which would be why it is drawing current, but the battery shouldn't be discharged that low.... even if the coil is drawing an amp in self resonance it shouldnt instantly discharge a 1.3 ah battery... and even then the charging battery would go over 13 volts immeadiatly... not 8 volts.. its resting voltage should still be above 12v.

[ren]

Sep has a good point. The battery is either seriously damaged or you have a connection problem with your multimeter. Does your battery read 12+ while at rest? It may sound stupid but check with some different leads plugged into your multimeter if it is giving confusing and conflicting information. Often with cheap leads the wire connection can break without the insulation breaking, I have a few sets that have done that.

Failing that you need to figure out if your circuit is drawing amperage when connected. It may pay to make your circuit again, screw or bolt the transistor down to a piece of board and solder all connections bar the resistance. Its a bit hard to see but do you have a diode between emitter and base? If you find the mje transistor small and hard to solder the 2n3055 or tip3055 are bigger and easier to make connections. There seems to be a significant bundle of mess around your pins and this can complicate things.

And yes for a small rotor you need to have an appropriate gap between magnets, at least 1/1/2 magnet spacings if possible. Id suggest a 4 magnet rotor.

Good luck.

Primary voltage of 1.76 V not going to help you.

Find yourself a old discarded wall wart that says output of between 9 - 20 V DC
use that as your power for your primary battery, I have also used an external hard drive power supply and my favorite is old laptop power supplies they work very well. You might find one on an old answering machine / portable telephone that will do the trick for you.

Your first step will be to condition your batteries, or to get new ones. Old batteries do work about 60 -80 % of the time ( if they have not been abused or lack electrolite or physical damage ) but can take weeks to get reconditioned.

I hope this helps I really think your input voltage is the problem. ( at least one of them )

Charger killer might had done it

Hey Ren maybe you are right i did buy a charger for my batteries. That i read it charger batteries 600mini amps is that bad or does it matter. I'll give you more detail about the charger if you need to see it later. Also one time when i was connect the batteries to transistor. The batteries were fully charge i would see a spark come fly out on to the metal of the transistor. Does that mean the transistor is drawing power before run the motor.

Sharing my progress

Hello All

Well I did not get the core I planned. The iron fillings became a challenge. So I found some metal tubing and small rods. Well pictures speak best.
And here are the links.

I did end up putting in a magnet out of a fan ( like in picture ) , it is on the
fat end of the coil. And of coarse the tip is pointed to the wheel and magnet.
The wire used for trigger and run is standard telephone cross connect wire.
