I am going to try to be the bigger man and do my best to ignore somebody who claimed my right to be inflamed! I had a pointed response but their right to not accept PM's has been employed, so it is in draft purgatory. This thread is monstor enough with out a bunch of bickering.
So this the generating end, alot goes on right here. I dont know what series motor this is or what it is a knock off of, maybe somebody can elaborate. Interesting that it has some of the makings and room for an electric starter but pulling that off would be a challenge, I doubt there is a ring gear in there along with no hole for it to poke thru.
Starting from the top and working in, that cone is what you turn when you pull the rope. A couple of dog ears fling out and catch the slots simple as that. Behind that is something that does alot of things, obviously moves the air, provides flywheel mass for the single to run smoothly and helping that is some big permanant magnets on the inside turning with it. Behind that is the stator and if you have ever been into the generating part of a motorcycle you can see where the idea came from, bunch of poles with windings around them. They are pretty rhobust as long as you dont overload them, that is one of the reasons why protection is required. Out of that comes six wires carrying three phase power and no brushes are necessary with this design. Very compact and efficient in comparison.
Quick epg class for those that may not know, in a conventional gen electromagnets turn on the inside so the output is contolled with a regulator making the them bigger in effect. Brushless designs do this with an induction set up. The speed must be constant depending on how many poles the generator has to get the desired alternating frequency. Inverting gens only need enough speed to keep up with the load.
Interesting input Prof... on the spl's and the patent issue!
For the record I am neither friend or foe of the open frames. They just were not a consideration for what I was looking for. I have seen one in action with a light load and was suprised at how loud it wasnt but the input from the generating police on here seem to indicate otherwise. I was looking into inverter types since I mostly dry camp and wanted something convienent, efficient and cheap for lots of uses but the icing on the cake was possibly power an a/c. Otherwise I was seriously considering a 2kw honda. I sold a coleman contractor open frame I had that paid for about half of this. I was doing some research on the inverter types when I found this site but didnt find alot on these.
