What seems like a simple fix turns out not to be so simple.
Question, I have an old mill with a waterwheel.
The shaft turns at 100 RPM. We figure based on what was there a minimum 300HP so 300 x 746 watts per HP, this has the potential to generate 223.8 Kw’s of electricity.
A 72 pole generator at 100 RPM will give me 60 hz AC.
So 72 x 100/60 gives me 120 changes per second through the coil. At this number of changes per second, to get 240 volts RMS (339v peak) how many winds of copper wire do I need to do this?
Wire wrapped around a iron core. Pass a dc current through the wire you get an electro-magnet. This electro-magnet will generate the field for the above coil, how many winds does this magnet have to have?
Given the above parameters this shouldn’t be that hard to figure out, but I can’t find the formulas to do it, can you help?
Not interested in putting in a transmission to increase the RPM.
Thanks!
Larry
