Hi.
I made a simple PMA a while back from MDF and to be honest it was pretty rubbish. I think that the magnets were too small and I didn't use enough turns in the coils.
It has got me thinking though. Is there a way of working out all of the variables to estimate the possible output? I am thinking on a larger scale. I want to produce 230v (as close as possible). I understand that it would be complicated and not extremely accurate but there must be an equation out there. I am not too worried about the current at this stage.
Number of turns, resistance per metre or wire, number of coils, size/number of magnets (flux?), revs per minute. etc
Which parts affect current and which affect voltage?
Any ideas. It's all theory for now, I'm just interested in what is possible.
Thanks
Paul
