Wow.
That is a silly amount of money..
The ameteks are good for what they are, (old tape drive motors) but not worth $300.

If I recall there was a thread on here where "The Boss" was being discussed and it didn't quite live up to it's expectations.
AH! There it is... http://preview.tinyurl.com/3ormc8

The links bring up something I always wondered about the UK guys. Why so few conversions?
Adding magnets to an induction motor is cheap and easy.
A scrounged 3 phase motor (350 or 450W), a few magnets, some time, and it works better than many versions of the Ameteks.
This thing was a 220VAC, 3 phase, 3600RPM.
Turned the rotor down in a lathe (could have done it with a file), epoxied in pieces of hard drive magnets (proper side up and grouped properly), coils can be reconfigured to suit the blades. It works great.
Photo is too wide to display here right, so a link.

Less work than a lot of the others!

Definatly worth considering Ghurd.
I believe Fungus has had some success with similaler homemade designs.

Funny that I should come across this post!
I guess there is a sucker born every minute cuz I'm the one that bought it for $399. Heh.
I'm actually rather pleased with the purchase... even though it was 400 bucks. I've been looking at a 1 Kw wind generator here and they go for about 3 grand without a tower (and the ones that I'm seeing commercially have fairly high wind speed startup requirements). Even at 400 bucks, I still see it as a reasonable deal to get good output. Will I see payback on my investment... maybe... maybe not. Not really the point in my eyes.
I see this as a fun hobby and it'll be great to get some significant power out of it.
Many people may say I overpaid... But for me it's a hobby... entertainment... Regardless, I'm happy and that's what's important. I'm sure the guy that sold it is pretty happy too.
So this having been said. Does anyone have any suggestions on blades for it? Been looking on e-bay for blades (not planning on making my own). Looking for something that starts in low wind as I'm not in a real high wind area (which is why I figured this would be a good genny for me).
Also, any thoughts on where to buy a good quality hub for this baby?

| I didnt call you a sucker, P.T. Barnum did. All kidding aside if i had the extra money laying around i would of bought it. I think if you just put blades on this it will be more like a 500w genny. You should use big blades and gear it up to use its full potential. You need close to 1000rpm to get that in the 1kw range and your not going to see that with just blades alone also the blades will not be on the genny so it would last you longer. |

No worries. I just thought it was humorous that I found that this tread talkin about the actual motor that I bought. No offense taken.
When you say to gear it up, are there ready made transmissions for this purpose, or are you talking about fabbing something up with either gearing or a belt system?
I have read the term before but have not found any site that shows it working in an actual application.
Also, why would the generator last longer in a geared up application over a direct drive?
Thanks,
Thomas
