I've tried reaching out to a few Chinese manufacturers and they are by and large not interested. They're often more expensive than iSta Breeze to boot. iSta Breeze has been eager to see their products tested and reviewed, I think they have a greater interest in seeing their products be successful. China is a weird mix of gambling, in my opinion...they're banking on shear volume to get enough sales to be successful, but are completely unwilling to work with anyone to demonstrate their products. Buying a Chinese turbine is a gamble in itself, and when the consumer gambles on the manufacturer's gamble, the consumer always loses.

@@ToysforWatts You have a great setup for testing and validating turbines. Seems to be a great fit if you were to test, endorse, and sell these things.

That's something I've found quite fascinating and it's made me wonder how important spacing is. This little 400 that actually works has that one large gap. My i1500 had a large, uneven gap on one side as well. Also the my i500 had one. All the rest of my Chinese turbines have had evenly spaced magnets. I can measure the gap this afternoon if you're really interested, but it's certainly there.

@@ToysforWatts Same here. My Tesup Master 940 turbine also has twelve magnets, with one large 10mm gap between two magnets and 3mm gaps between all the other magnets.

You want just the generator or a wind turbine? I'm a HUGE fan of iSta Breeze and they sell the bare generators on their site. You can get the i1000 or i1500 pretty cheap and they are proven machines, though they do require a pretty high RPM...which means good blades and mounted pretty high or, if you're using water, some pretty steep gearing. But you can even get the Heli 2.0 motor which is a low RPM 2kw rig for $700~ish (usd).

Hi victor! I'm sorry but I don't know what you mean by "the brass". What brass are you using? Tell me more about how you have it set up.

The other ends of these leads are supposed to be connected, so there should be continuity. Iron core stators (coils with iron in the center) always have a pulsing brake effect (also known as cogging) because the magnets are attracted to the iron cores.

By design I'm not sure, but I've never seen one of the cheap "tail up" turbines work well and have had multiple "tail down" turbines do pretty well.

Thanks a lot for that info. That pretty well sums it up for me. Looks like I will be going with a tail down design.👍

Would also want to know!

Lol

I haven't had to buy one but you should be able to take yours out and into any bearing supply and get a replacement (and probably a better one).

They were both unbranded generic eBay purchases. It's one of the things about the cheap turbines that makes it more risky and difficult to know what you're getting...they all look the same, but they are not all made the same.

@@ToysforWatts it's too bad really. Would be nice if the better of the two manufacturers would give us all a way to find them.

Yes it is a shame. I'm rather convinced that it was not sold intentionally...there are models that look exactly the same but go for $300~500 out of a China. I'd wager it was one of those accidentally sold at the "toy" rate.

I would definitely pop the nose off and take a look at what the stator and rotor look like. This little 400w turbine has set the standard for me. When I pull them apart I expect the rotors and stators to look like that...if they don't, my expectations drop through the floor.

@@ToysforWatts Yea i will do that , i have order a Vertical turbine for testing ... so this will go down :-) ,

Some of Chinese wind turbines supplier post fake specification to catch on your orders, because they are not manufacturer and sourced units from same manufacturer, only made fake rated power information won orders

@@ToysforWatts when buying wind turbine buy on weight !!

That can be pretty tough to go on, too, though. The two turbines in this video both weighed pretty close to the same. I've recently been trying to find a consumer grade 1~2kw vertical axis turbine to play with and came across one that had the paper specs I was looking for with a 1kw turbine...but weighed 600kg.

Unfortunately finding them on purpose is pretty tricky. With just about any small cheap turbine you have to actually hold it in your hand and look at the coils to know for certain. The reason why I don't test the cheap Chinese models much anymore is because the results are difficult to reproduce. Even same model numbers from the same vendor can be different on the inside. I generally suggest that people try to focus on known good brands like iSta Breeze.

@@ToysforWatts Greetings to #Texas :D (numberplates!)

Unfortunately I can only direct you on what to look out for, trying to buy the same turbine over and over again from Chinese manufacturers is difficult to say the least...the same listing from the same vendor can yield wildly different results.

eBay. This is why I stopped playing so much with the little cheap Chinese turbines. They all look the same on the outside, but on the inside they can be wildly different. The little turbine that had the good stator wasn't in any significant way different on the outside from all the ones with the weak stators.

If I get one to play with I might just for kicks :)

Yeah my most watched video is putting one of those things on the roof of my car to test output after the seller told me it just "needed more wind".

Link to a working version 😄👍

Hi Cid! Unfortunately the good turbine here (the one I'm sure you're interested in finding a link to) has not been available for some time. I think this is the closest safe bet to it, though: www.ebay.com/itm/400W-Wind-Turbine-Generator-DC-12V-Charger-Controller-Home-Power-5-Blades/393004720536?_trkparms=ispr%3D1&hash=item5b80e82198:g:lQkAAOSwf6heQP7W&amdata=enc%3AAQAFAAACgBaobrjLl8XobRIiIML1V4Imu%252Fn%252BzU5L90Z278x5ickkyMJZWL%252BqFSgQ3TOOe%252FNr7uQXqtTiw6pfRf4IYEPaSppfYEMWBhzbM3gr4Wwuo5oa3Gxdwgx%252BanTIGFf84AFs9YTNvrp5nNEmg7cfRxXBWyJESBznDgKMc3%252FtzMJx4BD0BYLePbBxY4HQzcoxzOaXYmyD7%252BTCC%252B9WJwOC4YzUmGl7sOywCvPl6pHcnnKPtVftSkFGs766KIbSRno9lapWrGyEJB3XRgpcd4ObrObuhyhf%252BP%252FESX5mWHpDSx3llEr1pIeCDonmpyDBdxKmwpzLt6dVSlYZw3duhQ154kifK50tm6EOBo5BWX7cQWoOcSDYoBewuAPEGbEPRBIfvgqJfPDzbH%252F4KIx%252BMIFRBdx8go%252Fh9QVGnEyOk7YnR8nEjZ2v4XMkkHzae8uHDDGDGjQQO4o5rkQhvjY4HqNwr5GlLuIlXDl2jCMyNgkdg4M3LDtiiL%252FH3es5NgDKZID25fZUOONdPJZMh2NFhNsl6LBHG5Vx2AcT%252BCKWvkqY4ZxSp%252Fe6BWc6YkvrGYCaL3JmvlS7tptjZovdougxrktTo7XuX9ovmtS2V0SwsCtx4%252FIUjJwg0BtjOaOJM7jDp95z7YCbEFJQLnBBmDvZPYxvP98Hv2L7O4H0wRuuUaYpcop1S9XjpRhuW2MIU6GaBEPysaJC3azGjvu5JW9t5CpDJ1DfTyZT0bZZF5zVSwClKi3vWRBR3lfBdFgRAUHWukbf0aLulKHaWiv48sMP5T1IyWOxs11IzE4kYTYZ7UFvh%252BTI8AWymvhWVKMfW9uV%252BHH7k1MJRRdmGaymQm1%252B8w55%252FNpjLBk%253D%7Ccksum%3A3930047205362948b7e31e0e439b9826ddf00be206d1%7Campid%3APL_CLK%7Cclp%3A2334524

@@ToysforWatts THE COMMENT IW AS LOOKING FOR. Found one similar...sounds like the best bet is to take them apart after you get them and check out the wires and magnets
