Hi, At the risk of annoying all you good folks - could I just get a direction on the stator set-up that I have mentioned. I know there are variables of which I appreciate - I just don't want to wreck my solar power regulator, batteries etc with their 40volt, 20amp restriction. So in light of that and not taking into account the wind, rotor etc, just the stator wiring for the 7 phase cogless set-up. So in essence, which one of these... So... 7Phase 1X6C = 6 coils wired in series. Max volts, good for 48 volts systems or 12 / 24 volts on a slow running turbine. 7Phase 2X3C = 2 lots of 3 coils. Less volts more current than above. 24v systems 7Phase 3X2C = 3 lots of 2 coils. 12v systems. 7Phase 6X1C = 6 lots of 1 coil, all wired in parallel. Max current, suits a fast windmill. 12v systems Regards, Somkey |

[Quote=Smokey 5159] . . . could I just get a direction on the stator set-up that I have mentioned? Yikes! First off, exactly where did you mention this? There are lots of varriables here. I think I'd rather tackle choosing the next 5 winning lottery numbers than figure this out. My advice would be to set up whatever it is you have and run it in various conditions against a meter. A meter will allow you to "go past" any crytical voltages or currents without frying things. For example, if you think it is going to put out 100 vac, set the meter in the 100 to 200 scale and that way if it actually does go above 100, you don't wind up with an order of "Extra Crispy". In the USA we have a chicken food chain called KFC and extra crispy is one of their benchmarks; everyone here knows the phrase. The point is to not fry your junk; test it first within known parameters and get a good grasp of what your rig can actually do BEFORE you set about to make any permanent installation. My hope is this helps you out some. If not, delve into more details in the reply box on this thread. . . . . . Mac Nothing difficult is ever easy!

Hi Mac, I posted this info 7 posts back... "an answer if I may" I don't think it's wise to test yet because I want to rewire the stator for a 7phase decogged motor. No sense in testing, because it is still in original form from factory. All I want to do is rewire it for a 12 volt charging system with a 40 volt, 20 amp max input - nothing more, nothing less. I can't do any test obviously until after I have rewired the stator. That's why I need to know what wiring configuration to do before I start the rewire. So, out of the 4 - 7phase selections above (1X6C, 2X3C, 3X2C, and 6X1C) - which one is guaranteed not to fry my solar regulator (40volts max and 20amps max). that is all I want to know. Please help!

Smokey5159 Oh. Well, if that's the case, then I'm not the one to ask. I was thinking it was a scratch-built thingy. I'm sure there are several folks here who understand your situation better than I, so just wait it out; someone will come along and help you out. And by the way, I can't seem to find 7 posts back. All this page shows is the post of July 9th, my and your reply, but there are no other pages as far as I can see. Maybe the 4m is broken; it's been under construction for a few days, I dunno. . . . . . Mac Nothing difficult is ever easy!

Hi Smokey No garentee's when it comes to wind. Without a furling system, in storm conditions, a 100 windmill could make double the power before flying apart. Many of the members here have had failures due to extreme conditions, its just the nature of the beast. There is no answer for so many unknown variables. Try a 1X6C, most likely to work in low winds and not burn out your controller, a good starting point. Later once you get to know the machine, you could try converting it to 2X3C, a fairly straight forward mod. Hope that helps, let us know how it goes.

Guys!!! Thanks heaps for getting back to me. Mac, appreciate your frankness - cheers Bro. Glenn, sounds like a good start - thanks for taking the time respond to me, a vague persistant wannabe. Mate, I am pretty mechanically minded, and understand a lot of what I have read in the project section. Is it ok with you though if I get stuck to quiz you now and then? Like my first question - where do these wires attach that disappear in-between the stators? 
And where it says... "I found if I unwind the outer coil one turn, it was then long enough to reach the next coil, 7 poles further around the stator". Does that mean fully unwinding a whole stator pole's length of wire, or just one turn?

Hello Be very afraid you most likely find smoke. I have been testing a long these lines. I have smoked up a lot of China grid ties here is a vid of one.http://youtu.be/jLx9KOaCLnw Here is my Mann Smart Drive set with 38 pole split wiring 3 phase. As I have said in other posts We are working on a Smart controller to let you use the Smart Drive and a stock wired stator and use the good low cost China grid ties saftly. Bob Mann |
