This woman has a ton of videos restoring old rotating machines, it's unbelievable. If you like this kinda stuff, there are so many more like it
This one is a little unusual because it's single phase rather than 3 phase, but it has more of an explanation than her others that I've seen
Yeah it's insane. May have procrastinated a bit and watched this one where she adds on to a (small) hydro generator she built, making a shelter for it and improving the amount of energy it can utilize.
