Wind generator charger schematics (or load of baloney ?)

Re: Wind generator charger schematics (or load of baloney ?)

Hot water has already been invented. You will find what you need in... motorcycles. Basically all pre-2000 (I'm not sure about the newer ones) have a magneto with 2 or 3 coils. I guess you can get the rectifiers from a motorcycle scrapyard or pick one of the many schematics available in google ( https://www.google.com/search?q=moto...=lnms&tbm=isch )

motorbikes are 3 phase .

Yes, I also have seen bikes with only 3 phases/coils (japan made), but apparently there are some with 2 and single phase ... like scooters, old ussr ones, etc.


p.s. my bad - now checked again the schematics, what I though that was a diagram of a 2phase rectifier was a single phase. So I guess even the ruskies did not make such a unicorn.

Great...the notification emails about this post suddenly ended up in my spam folder for whatever reason, so I had no idea people replied FAIL

True, I haven't seen a single one of this guy's inventions so far, so I too have no idea what's supposed to happen there....and I'm not curious to find out anyway, since that's NOT what I'd use for this project to begin with as far as the electronics are concerned.
I also agree with not wanting to reinvent the wheel here. As much as I like the idea of DIY turbines as a hobby and for a bit of fun and experimenting in the name of science, I'm not ready to put in a lot of time and effort into something that's already been invented AND is much better off the shelf than I'd ever be able to make it. The idea of a bridge rectifier on the output still seems to go right past this guy

I also had a brain-fart: last summer, I upgraded the motor on my E-bike to a bigger one and I remember such motors are BLDC motors, which conveniently have 3 wires for power. Although I no longer have the old motor to experiment with, because I sold it, it got me thinking whether such an E-bike motor would function as a generator.

It might if it has a permanent magnet in the motor

shouldn't matter if the field coils can be excited .

Re: Wind generator charger schematics (or load of baloney ?)

I doubt it's got field coils. It's most likely a BLDC with the magnets stuck to the outer casing that spins around the stator coils. It's backed up by the fact that it's got 3 main wires coming out of it and although it has another connector with a bunch of smaller pins as well, that's most likely for some sort of speed/position sensors, as the wires are way to fine a gauge to be anything else, like power. Field coils would probably waste power to begin with, which isn't something we want. I was thinking about a car alternator, but it's the same problem: no permanent magnets, unless I modify it...

Right now, I'm still waiting for the guy to tell me what happens to the joule thief circuit once he tries it out

Here's how I'd imagine a small-ish DIY charge controller for home use. The components can be up-scaled as needed for bigger stuff, of course. That battery switch is a little tricky, as it has to open when the turbine turns (charge mode) and close when the wind stops (battery mode). I see an op-amp in there somewhere maybe...

Victron already has this stuff pre-made from what I gather.
