DougI have a hunch that he is doing something quite simple, and we are over thinking this perhaps.My 90lb flywheel is going to be mounted on a shaft with bearings.Once completed, I will pester everybody with motor ideas. This is the inertia belt driven type of device we see so often.I just had to do it, since I have the bits and pieces to make it.Although my big lathe is still in Toronto, this is a little thing that I can do with simple tools.My drill presses and wood lathe are here.I might just go with a plastic hub, turned from grey pvc.The snow has finally gone with several days of heavy rain this week.Stone buildings serve as heat capacitors.The house walls are 32" solid stone, while the barns are 24" thick.We had those warm days, and it was like working in a freezer in the stone barn.After several warm days, I feel like I can finally get some work done.Next year, I hope to have heat installed in tubes under the floor like it is common in Germany, and use heat pumps. Even not insulated, once you heat stone it just radiates for days.My neighbours with stone houses are not paying any more to heat than those with modern construction of the same floor area. I am just learning all I can.Cheers Warren

Hi Warren
I watched the Indonesian video a few more times, and that sure looks like a car alternator on the left side!
I looked at Universal AC DC motorsm and they have (what I have seen) two brushes at 180 degrees on both sides of shaft at one end of shaft, and the brushes are very visible too, but I see none of these on the presumed motor on left side, and it looks just like a common car alternator to me still, also there are only three wires going into it (red white blue) so this also makes me wonder if it is car alternator...
.Also look at the presumed generator/alternator on the right - for sure this looks just like a generator out of a common genset, but maybe he is using that as motor (somehow) and note there are two wires coming from it, so it must be single phase.... thinking backwards, maybe this is not a genset generator but a motor for a waterpump or electric rickshaw/motorcycle....(doubt it) but he has an earlier video with a rickshaw that has solar panels mounted on it....he shows the invertor he uses later (but with label off) and it is 1500W type, and 230VA....so if this is AC to AC motor generator, he is running on 230VAC I presume and will guess..
I looked up converting car alternators into motors ....doesn't seem so practical to do unless 3ph and you have 3ph controllers I don't think he uses these in video.......
could be his :car alternator: rotor is specially made with permanent magnets in it, and stators also special, in that they hug the stator housing, and it becomes an AC motor.....I have built motors like this (that run on AC) but mine were "axial: like flat disc muller designs, but no reason not to do it all inside a car alternator housing and would not be that difficult either here is video I did of my permanent-magnet AC motors that work great as you have two magnets on each side of coil, pulling and pushing same time...at 1:20 I explain, at 2:20 it should make sense....anyways imagine doing something just like this all contained into car alternator housing....(tthis AC motor design one of best thing I have come up with) IFthat generator on right side makes 60hz for example at 1800 rpm (4pole) or 60hz for example at 3600rpm (2 pole) then you could construct the AC motor inside the car alternator housing to synch up with what the generator makes by either 4 N-S magnets, or 2 larger size N-S magnets and corresponding coil sizes within the stator housing
