Rectify

[JW]

Have a friend that says you generate DC off a coil, we know this is AC.

Can anyone point out a link to a basic page.

[ruddycrazy]

don't have a page at hand but a basic explanation should do the trick....

In order to get AC from a coil it needs to pulsed at a certain hertz 50 over the pond and 60 over there, then a bridge rectifier using 4 diodes for a full bridge or 2 for a half bridge with a cap to smooth out the rough DC output will produce DC.

I found this schematic should help. You can clearly see how the coil makes AC that has to be rectified with a bridge.

Tell him to look at any vehicle diagram, because that's how all stators work

I remember the old car generators...     Like TechAdmin said.   

Mechanical rectifier if I ever say one !

CooL old tech.

Gone are the day when you could open it up, take a finger nail file to the points and get it back to not sticking.
SOooo darn easy to work on or rewind.
