Parts are listed in instructable step 1.8 numbers of 1N4001 Diodes which operate at 50V 1 Amp is good for your use.As for capacitors you can use anything from 220uf to 470uf will do.You cam follow the power Plant Schematic Circuit Diagram in the instructable.But look at your spec on the generator, you can't get high current from that, the most is 100 to 200mA, can't power a robot.BTW what are you want to operate with it?
I think that is a 3 phase motor. We plan to rotate it at 60,000 rpm. So because it's back EMF constant is 0.159 mV/RPM, I think we will get a voltage from it of 9.54 Volts from each of the 3 leads coming off of it.Did I do that right? Note: I'm not sure whether that voltage represents RMS voltage or peak voltage.
Then, I think we can use these diodes, the type you recommended in your last post Soeren, Schottky: 1N5817www.onsemi.com/pub_link/Collateral/1N5817-D.PDF
Now, our turbine outputs roughly 5 watts. So if our voltage is roughly 10 volts for each phase, I think we should see a current output of roughly 0.1667 amps (=5 watts/ 3 leads/ 10 volts ) from each of the three leads. And that PDF claims that "Average Rectified Forward Current" is equal to 1 AMP. Assuming "Average Rectified Forward Current" refers to the average current the diode can handle, we are less than its rated value of 1 A so we should be ok.
I'm also confused about what I should do with the 3 DC outputs from the three different diode bridges I make. Can/should I hook them up in series to get roughly a 30 volt/0.1667 amp output? Or should/can I put them in parallel to get an output of roughly 10 volts / 0.5 amp. That one is confusing me.
