Hello
I have been working on my SSG from the SG Handbook and still testing the small motor with 9V batteries.
Latter on I will move up in scale until I understand how it works.
So I made a video to show what´s going on at the moment.
SSG replication, high resistance lower Amp draw more speed. - YouTube
Special the tuning have been interesting for me to play with along with the coils I have been testing.
However her is my result with a simple math and it is pretty awesome.
Battery I: 9V NiMh
Normal charge: 20 hour
Volt: 230
Amp: 0,04
Watt: 9,2
DISCHARGE - 12V bulb: 3,15 hours
Battery II: 9V NiMh
SSG charge: 3 hour
Volt: 9
Amp: 0,250
Watt: 2,4
DISCHARGE - 12V bulb: 3,30 hours
I gain 15 min more than the traditional charge, plus shorter time to do that.
But I am still a little confuse about the timing for tuning.
If I put the scope on to the emitter and collector I do not see one spike only I see four spikes or two depend on the speed and resistance. They all have the "H" form as seen on pictures. But I do not have one spike.
So my question is: Should there be one spike only ?
What impressed me is high resistance seem to speed up the motor, normally that´s opposite.
If I put load on the back end of the secondary battery or any other motor, electromagnet it does not drag more power from the primary battery and the amp is standing at the same place.
Last if I put resistance on the rotor with my finger it still keeping the same amp draw and the same if I put extra coils to the rotor. It still keeping the same speed and amp.
Thanks for all the post I have been reading, really fantastic
- And thanks to all the folks who want to share there know how on this subject

I would also know if I'm supposed to have one spike only as I seem to have groups of 8 or so and as I decrease resistance there are less. But by the time I get to one, the amp draw is too high (1 Amp plus). Seems to charge okay with the pulse groups though, but yes I wonder if the timing is best. The behavior of your machine seems pretty close to mine, but your amp drops are more dramatic!
