I have a Chi Hua Precor motor, 240vdc,4200rpm,12 amp Model # MBO-302442BA Which blade set would be good for this motor ??? Thanx Wayne
I think three turbotorque blades will be just fine for that motor. The volt to rpm ratio is good on that motor and it should have no problem charging a 12 volt battery.
I have a 120 vdc 8.2 amp at 3200rpm pm motor and live in a high wind area with common winds at 20 mph or more. Which of your blades are best suited for me?
I would recommend reading our article on how to choose a motor which will give you a good idea of how applicable your motor is for use in a wind turbine: http://www.windynation.com/articles/wind/making-wind-power-how-choose-right-motor The volts to rpm ratio for your motor is 0.0375 which means your wind turbine will have to reach about 375 rpm to start to charge a 12 volt battery. This is a fairly high rpm but a very realistic rpm for a wind turbine. Based on the size of your motor and the rpm requirements, I would recommend five TurboTorque blades. This should get a 12 volt battery to start charging in about 8-10 mph wind. http://www.windynation.com/products...ets/24-inch-turbotorque-aluminum-blades-set-5
I have a pma with a 12v bank. my local windspeed is about 5-10 mph on average. (south central ky) my listed pma specs are 24v at 680 rpm, 22 amps. Which blades would work good?
I purchased a WindBlue 540 system about 8 months ago and I am not entirely happy with the blade set. My area averages 5-15 mph. I would like to improve my system with a new hub and blades, what would you recommend?
From feedback from customers, I would recommend our five HyperSpin blades for the WindBlue 540. There is a bit of cogging in this alternator and the five HyperSpin blades really help to get this particular generator spinning in low winds. This blade set will improve the performance of your WindBlue. http://www.windynation.com/products...-sets/28-inch-hyperspin-aluminum-blades-set-5
I have a Siemens permanent magnet motor 163 V, 3000 RPM, 1,4 KW with hold break (24V). Thinking of using it as a Windmill generator to 24V system. The shaft is 18mm. What blades do you suggest 3 or 5 pcs (I live in west coast of Norway with High winds)?
Hi Take a look at our article "How to choose a motor" http://www.windynation.com/articles/wind/making-wind-power-how-choose-right-motor Your motor will work well with three or five HyperSpin blades. I would go with three if the motor is easy to spin with your hand and five blades if the motor gives you resistance when you try to spin it with your hand. If you are unsure if it is easy or hard to spin, then you are better off going with the five blades. Based on the rpm and voltage rating of your motor, you should start charging a 12 volt battery bank in ~8-9 mph wind and a 24 volt battery bank in ~11-12 mph wind. If you are in a high wind area, then you should have no problem charging a 24 volt battery bank with your motor.
"Which blades should I use for "wind generator turbine super patroit pma alternator 12 v" 5/8 hub?" I would go with our Five HyperSpin blades. These are your best bet. I think the patriot has a 17 mm shaft so you will need our 17 mm hub (not 5/8 inch hub). Best to measure the diameter of the altenator shaft to make sure.
I want to charge a 12 volt system. The treadmill motor is 260 VDC 5100 RPM 5 amps 2.25 HP @ 260 VDC The shaft has 1/2 X 13 left hand threads 7/8 of the shaft is threaded. The rest of the shaft about a inch is o.67 in dia. there is a flat sholder at the transition. The total shaft length from the motor to the end is 1 7/8 I think i will need a hub and arbor to attach them. If I can get a left hand threaded nut that fits the shaft can I just tighten the hub the the shaft with that nut
The motor should work well as a small wind turbine: http://www.windynation.com/articles/wind/making-wind-power-how-choose-right-motor The turbotorque blades will work very well on that motor and LH threaded nuts are readily available online for purchase from fastener web sites.
What blades would you reccomend for a 240 volt dc motor at 1750 rpm; it weighs 40 pounds? With 7.29 rpm per volt do I need large blades?
From the details you have provided I do think the WindGrabber blades will work well on this motor. If the motor is difficult to turn and seems to cog, then go with five WindGrabber blades. If it is easy to turn be hand, three WindGrabber blades should be sufficient.
I just read your article on how to select a motor. This motor is 220 volts but only 3.7 amps, which is below your reccomendation. But would it be ok because of the high voltage output?
Well, it will work but you are not going to get a lot of power out of it. As long as you are OK with not producing much amps with that motor then I would say go for it. If you want to make more power then you will need to find something that can give you more amps. You might see 10 amps out of that motor but probably not much more than that.
I have a large axial flux 1000 watt 32 magnet motor, desiged for low speed. I need a high torque blade system that can power the motor in 5 to 7 mph winds, and withstand occasional sustained winds of 20 to 30mph. I will be using a self furling mount that activates over 35 mph. I see you have several blade systen available, but need your recommendation for my application. I will machine my own hub, as we will be experimenting with a governed sytem to limit rpm's in lieu of a the furling system
From the description of your axial flux generator, it sounds like it is a real beast. I assume it is 16 magnets on the front and 16 magnets on the back with a 9 coil stator wired 3 phase in the middle? This is a big generator. What size are the magnets? Our WindGrabber blades might work but I think you would be better off with a ~48 inch blade to power this beast. It depends on the size of your magnets and the strength (N42?). Let me know the size and strength.
