Wind Generator Motors Rpm
More Help With DC motors?
I am doing a science fair experiment in which i am creating a mini wind turbine, which will create electricty. For me to do that, I need a motor that can be spun to create electicty. the turbine wont be big and it will be put into moderate wind, maybe as much as a fan. I need a motor, which can act like a generator, that will be able to spin with that amount of wind and still produce some electricty. The motor's RPM cant b too high because i cant get the blades to spin too much. I had asked a smiliar question before, showing a Permanent Magnet 12V 30 RPM motor. Someone said that 30 RPM will be tough to spin by moderate wind, so i found anotehr Moter which is 12V Permenant magnet 160 RPM. Will that be able to spin in moderate wind?
Also, if i make it spin 160 times will i produce 12 volts or lesss?
thank you.
I'm just guessing, you really have to get the motor and see how easily it is to spin.
Motors are not the best generators, you would have to try it to see how much power you get out. One important thing to note, the lower resistance you load the generator with, ie, the more current you draw out of it, the more force it takes to spin the generator.
In other words, the drag, the force needed to spin it, has several components. first is due to gears and bearings, and is pretty constant. The other is the drag caused by the magnetic fields, and depends on the load. No load, least drag.
