Hello all. My first post. First let me say thanks to you Glen for this fascinating site. Full of excellent info and great photos. A windmill constructors dream.... We (myself & Mrs) will be moving to Portland (400 k west of Melb) in a few months. This is the land of windiness, with several wind-farms there amd more to follow. I have purchased a 5 acre block there and will be building a house in a few months. So far I have a big shed with room for 3 cars and a workshop. We have a caravan to live in while the house gets built. I will be building a wind generator to your design. I have an F&P motor in excellent condition. Question: How can I tell what model motor it is? The wire looks less than 1 mil but its hard to tell? Question 2: In some of your pictures it looks like the coils have been rewound. Is this so? Question 3: How do you keep the weather out of the f&p stator? I will put some pics up on my web site soon to show my progress. Or maybe upload them if i can work out how Thanks again Peter Let the wind blow high Let the wind blow low Through the streets in my kilt I go |

Hi Peter. I've been to Portland. Nice place, a lot to see, but a bit cold for a Queenslander. We drove past one of the big windfarms, I wish I could have got a closer look, but it was closed to the public. We call the F&P types 100, 80 and 60. But this is not how F&P name them, they use model numbers. A 100 has 1mm wire, the 80 has 0.8mm wire, and 60 is 0.6mm wire. I dont have a photo of a 100, but this is a 80 
And this is a 60, yeah they look rewound, but thats normal 
That answers your questions 1 and 2. To keep the water out, I paint the stator with some clear varnish, but any good paint will do. Dont forget the ends of the poles where the laminations poke through, as these will rust in time. There is a 0.5mm gap between the laminations and magents, so dont go overboard on paint in this area. We also paint the magent hub and any plastic, as UV will damage them, 1 year in the sun will cause the plastic to start flaking. Good luck with the windmill.

Hi Glenn, Thanks for the hints & photos. I think mine must be an 80. I counted the turns across the coils (yours & mine) and got about 27 in each case. Here is a pic of mine. Do you think an 80? Peter  Let the wind blow high Let the wind blow low Through the streets in my kilt I go |

Yeah thats a 80. I found a pic of a 100, real chunky looking compared to a 80 or 60. 
And these are the two hub types you will see. The 100's hub had individual magnets. The 100's are very rare these days, they were only used on the early models. 
F&P later changed the hubs to these wider magnets. Each of these magnets is actually made up of 4 magnets side by side, you can just see some faint lines across the magnet where the poles meet and have attracted metal filings. I believe they did it to reduce the whine noise made by the washing machines on spin cycle, but I could be wrong, may have been cheaper this way.
