Hi Everyone,
Been a long time since I posted, mainly because I haven't been SSG'ing for a couple of months but now I'm back.
So I bought Paul Babcock's latest Magnetic Energy Secrets and something he said about his 24V SSG put an idea into my head. What he said was "If you take the energy out at exactly the right time at a 90° degree angle I get no push or pull reactions that slow that thing down and make you pay a mechanical price"
So with that in mind I attached my timing light on the coil perpendicular to the passing magnets and then proceeded to alter the coil gap and resistance until the magnets created a visual "bar" close to dead center (or 90°) to the iron core, this was once the wheel was up to speed as this alignment changes based on RPM - see video for what I mean. This resulted in the highest RPM for the lowest amp draw but I need to stress something... This was NOT the highest RPM that the machine can attain. I can get my machine to go much faster especially if the gap is only about 3 mm or so and I kick start it by shorting a high resistance 10W series resistor for example.
In this current configuration i am using 330ohm base resistance, 16.7Ohm 10W series, gap is about 8mm and RPM about 285 with 21 magnets, it draws about 1.2A. I have to give it a "fling" at startup to get it to single pulse.
I am starting some full runs to get COP info so we'll see how it goes. I can tell already that it's probably not going to be earth shattering, I am still very suspicious of my test batteries being garbage... Anyway.
The change of alignment with RPM speed has me thinking about the resistance applied to an SSG such as fans or generators coils. I am also going to test various resistance levels, gaps etc in an effort to get the coil close to saturation but not quite!
Having thought about Paul's statement some more it makes sense because before or after 90° means the coil electromagnet is pulling or pushing against the permanent magnets. At 90° the electromagnet dissipates allowing the permanent magnet to escape.
Also here is some pics of what I'm calling my "CLASSIC" ssg built along the lines of JB's original.
