I've done a bit of that too over the years, just a
few motors but more
transformers. One thing that has always troubled me is the usual poor
I;ve done trasnformers too, but fortunately I've never had to do one that
had to stand main voltage or similar.
condition of what I believe is at least sometimes
called the "fish
paper" used to provide extra insulation between the coating on the wires
I've certainly heard it called 'fish paper' over here. I am not sure if
you can still buy it anywhere, if you can, I am looking for a source...
and the stator/armature/core metal. Back in my
younger more foolish
days I'm afraid I was sometimes guilty of using ordinary card stock as a
solution, though I've wondered if that is not a bit of a fire hazard in
Well, it probably is eeasier to ignite than fishpaper, but normal paper
is not that easy to set on firs. A soldering iron won't do it, for
example. If a transformer is getting hot enough to ignite paper, you have
problems.
My greater worry would be that the paper may absorb moisture and
electrically break down.At one time paper soaked in wax was used, but
this would seem to be an even greater fire risk.
spite of "Fahrenheit 451". I'd just be
interested in hearing your
thoughts on this issue.
I'd probably not do it in something that was going to be used by somebody
else, or somethign that was going to run unattended. I might do it for
something I was goping to use myself.
