Tiny Alternator from Kubota, Nice for tractor builds...

I was just looking through some stuff trying to find a light weight alternator after discovering that ARC's billet flywheels don't have any charging magnets. Saw this on amazon. It's a small alternator that puts out 14amps (12 volts). There is also a 20amp model for a bit more $$$. It's supposed to weigh 3.5 lbs. I'm trying to find out what the dimensions are but it looks small. Just thought it might help someone out if they wanted a small alternator to fit their project. Car alternators can be pretty big.

If I end up ordering one, I will post some pics to show the size better. They look pretty cool. Guess they are for a kubota engine.


Also looks easier to make a mount for it than a car alternator.

Yeah I've seen ads for those little units a bunch of times and they always seemed like a perfect compact little unit. I thought you could even use one for a vertical shaft engine really, being that they're so small.

I'm looking forward to seeing how it works for ya!

Wow, that is small. Is it internally regulated?

Never mind. Seen the regulator on the bottom of the page for it.

I guess you need to run a regulator yeah. I'm thinking that's the way to go for my new build though if I run an ARC flywheel. Too bad they don't just have the charging magnets in their flywheels though. I heard the stock briggs charging coils only put out like 3 amps? So this would be a step up anyway.

I almost had one of these, the one on my friend's kubota seized and he bought a new one. I didn't think to ask for it before he threw it out. If only.

As far as I can tell, it is only a magnet on the pulley and a stator. Would like to see how the stator is made.

Very cool find!

Thanks. It's not like having a car alternator maybe, but might be better output than the stock system. If I get one later on I will check it out with a meter and see.
