i have a motor will this one make a good windmill and how big do i make the props ? 100 RPM - approx. 13.4 V approx. 330 Watts 125 RPM - approx. 16,7Volt - approx. 414 Watts 250 RPM - ca33,2Volt - approx. 825 Watts 500 rpm - approx. 66.5 V - approx. 1.65 KW ca 1000 RPM - approx. 133Volt - 3.3 KW ca 2000 RPM - approx. 266Volt - 6.6 KW with each 220Volt-2 KW - with zero-leader. approx. 3000 rpm - approx. 400Volt - 9.8 KW Feed into three phases 380 V of 6KW heating staff, three-phase alternating current without zero-leaders thanks for your reply and help
i have a motor will this one make a good windmill and how big do i make the props ? 100 RPM - approx. 13.4 V approx. 330 Watts Yes it will work just fine for a 12 or 24 volt system 125 RPM - approx. 16,7Volt - approx. 414 Watts Yes it will work just fine for a 12 or 24 volt system 250 RPM - ca33,2Volt - approx. 825 Watts Yes it will work just fine for a 12 volt system 500 rpm - approx. 66.5 V - approx. 1.65 KW ca Yes it will work just fine for a 12 or 24 volt system 1000 RPM - approx. 133Volt - 3.3 KW ca Yes it will work just fine for a 12 or 24 volt system 2000 RPM - approx. 266Volt - 6.6 KW with each 220Volt-2 KW - with zero-leader. approx.

SNAP!) In a nut shell, all those motors are very good candidates.
hello windyguru sorry for the bad info the rpm speeds are from one motor so the is just one motor the shaft diameter is 0,946 inch = 2,404 mm length of the shaft = 1,966 inch = 49,95 mm weigh of motor is 18kg = 39,68 lbs thanks
From the specs. you have stated, the motor is excellent. It will work great. I would go for a big set of blades. Something around 80-85 inch diameter. If you go any higher than that, you will have trouble reaching charging voltage in low to medium-low wind conditions. I know Windy Nation sells an 80 inch rotor on ebay but it is not in their store. It would be a very good candidate. Stay away from PVC blades unless you are looking for a disaster. - PD
hello i have seen the 80 inch blades on eBay Windy Nation i also see 5 blades design but not in 80 inch form Windy Nation with this motor is 3 or 5 blades better ? but i am not sure if this is big Enough for this power house of a motor you right about PVC blades i don't like disaster so i stay away form them any help and info is appreciated ofcourse thanks ray
Well, the 80 inch blades would be powerful enough to make some good Watts. You could probably do close to 1000 Watts in 25 mph wind. The motor itself could handle larger blades but you will run into a little engineering problem. As the blade length gets longer, the rotor will obviously not spin as fast at a given wind speed. You need to generate at least 12-14 Volts to charge a 12 Volt battery bank (and 24-28 Volts to charge a 24 Volt battery bank). If you start thinking about making the blades longer than 85 inches, then it is going to be hard to get charging Voltages without good winds. Your generator will "miss" a lot of energy from the low to medium low wind days which are the most common. You can always get around this problem using a gear. You can have a 2:1 gear in which the shaft of the generator spins twice as fast as the blades. You could then use larger blades. However, gearing wind generators is not easy as the gears fail fairly easily if not built well and require a lot of engineering and maintenance. Unless you really like a challenge, I would stay away from this idea.
