As suggested, try it and see - EPE did a hand powered LED torch using a steppera gfew years back. However, I can't help but think that a normal DC motor would be a better bet.
Disagree. But rectifier design may vary based on type of stepper motor.Yeah but the output of a stepper is multi phase AC, harder to rectify, DC motors you can use with just a simple filter cap.
DC Generators
* Advantages: Simple and pre-assembled, some are good at low rpm.
* Disadvantages: High maintenance, most are not good at low rpm, large sizes very hard to find, small ones have limited power output.
* Suitability for Wind Power: POOR to OK
A brushless DC permanent magnet motor is really just a permanent magnet alternator! A special driver circuit provides AC power that is in phase with the rotation. If you are able to find a large one of these surplus, it's possible you might have an excellent start for a wind power project. They are used in robotics and precision control applications, and some use Nd-Fe-B magnets for high torque in a small space. As with surplus tape drive motors, we would not trust the bearings to stand up in a wind power application...add more bearings so you don't ruin the motor's original front bearing.
Altough this is my first wind generator(using stepper motors) i have tried using Dc motors(12v) and they gave very little output. The only problem with stepper motor(mechanical) will be(my assumption) is the large torque required to get it rotating.I guess extra large blades will do the trick?
You should learn how a multiphase rectifier work before posting.Okay so eight diodes with at least what 2 or 4 diode drops as loss, as opposed to a brushed Dc motor with a capacitor???
That's making power from nothing. But we are making power from wind. A little more air blowing there for a bigger genrator.Sceadwian makes power from dead cels and in his work there can be no loss so he has a point. He lit two leds from nao volts
