There are 3 "stators" there. The small "pulse" coil for the ignition firing. The large coil on the right (presumably for the ignition), and then the 3 copper-colored coils, which do the lighting/battery charging.
The ignition power stator is a two pole unit, the lighting stator coil assembly is a 3 pole.
The ignition power stator is a two pole unit, the lighting stator coil assembly is a 3 pole.
Thank you Sir for your response.
So essentially, If I would to look to buy the same set-up (not taking the pulse coil into account), do I look for 3-pole or five pole stator?
The pulse coil is shoe-honed in there.
Thank you Sir, kindly.

I have never heard of a 5 pole stator. 3 is by far the most common. Additional pole will not help because there is nothing to connect the additional outs to down stream (unless the diodes are built in).
If your goal is more power, I have heard of people rewinding stators with more turns of wire.

3 pole stator. The ignition stator is independent, and not part of the main lighting/battery charging stator besides being bolted to the same plate.
Thank you Sir's. I am not looking for more power etc. Just looking to reproduce exactly what is shown in the picture. I will now start to look for a 3-pole stator with the ohm values for a over 35 year old motorcycle that I am trying to restore and convert into points. My next big challenge is getting my hands on the brass or aluminum stator plate to mount them coils.
Thank once again Sir's for your guidance and help, much appreciated.

What make and model is the motorcycle? It looks like a 2-stroke, and I think you'll have a difficult time trying to convert it to breaker points. There should be parts available unless it came from the USSR or China.

LOL made me chuckle
why convert to points? usually it's the other way around. there are ways to use Honda postie parts to convert (very common in Europe/Asia) if you have a hard to find CDI box go bad. you need to know if you are running ac or dc cdi, and if the box has the ignition curve built in or the advance is mechanical. the latter is easiest, but chinese scooter (honda clone) parts as well as GM HEI parts are also easily adaptable.

Year, make, and model of motorcycle, please.
The GJ Hive Mind has some surprising and obscure bits and pieces of knowledge squirreled away, and more specifics will help its biological search algorithm point you to the correct parts and procedures. Whatever machine this is, there's probably a forum out there somewhere for it and a good chance someone has been down this path.
And yes, that's a simple three phase three pole stator to generate a bit of electricity, along with a ignition stator attached to one side. They are not electrically linked up; you'll have five wires coming out of that area.
The first-generation KLR650 has a similar setup, except it's three phase with 15 poles, combined with two ignition poles.
And yes, if you look at the waveform of the AC output of one of these, it's asymmetric, which overall doesn't make much difference. You lose a bit of efficiency, but it makes things simpler.

Sorry Gentlemen: I just realized after re-reading my post. I made a typo.
I am looking to convert my bike from CB Points to CDI/electronic iggy.
The bike in question is a 1973 Yamaha RD350B. Its a 2-stroke engine, passed down to me by my father.....

Post some RD350 pics, I always wanted one of those bikes.
"JP7 Simple CDI Motorcycle ignition system" - this is the method I was referring to and used myself on a Honda 180. his site seems to be gone however...fortunately, I saved his info in a pdf file I can share if you PM me.

If you Google "RD350 Electronic Ignition" there are tons of options. It's one of the best-loved classic motorcycles ever made, so information and parts are plentiful.
As far as which one to pick, I dunno. Guess you'll have to do some reading.
For the classic Suzukis I'm into, there are very few options. One, really.
