Subject: Permanent Magnet Backup
Generator
Many years ago we discussed on the list various ways to
implement backup electrical sources for our electrically dependent engines. A
great amount of discussion was around permanent magnet type of
generators.
An idea was hatched and discussed, then
forgotten. Except I didn't. Some years and a few sleepless nights later I set
upon achieving this. Most of the work was done and reported to the list quite
a few years back, but at that time I knew I had to set it aside for some time
as I had other commitments.
At last report I had finalized the mechanical aspect
but had made no attempt to integrate it into the electrical system. I've now
finalized this and yesterday ran the engine for the first time. Everything
worked excellent! So far it seems to have been a tremendous
success.
So I have updated my word document of the procedures
for this modification. Including a wiring diagram.
For your entertainment I've put it on Google Drive in Word
format where it can be accessed at the following link
or for us Linux types in .odt
