Hi- I searched a bit but could not find anything related to this. I have broken down my second electric motor, fairly large and quite old, and the windings are two gauges of copper wire with a very fine fiber wrapping, like fine thread. Because the gauge is fairly small its hard to strip this stuff off, also its kind of soaked in oil. I wondered if anyone had a way to clean it off, technically its insulated but not with plastic. Not sure I can include it with my stripped #2 wire.
Thanks Tdean
Can you post pictures? Its kind of hard to help without visuals.
I think I know what you are talking about. If I open a motor and see it, I dont even bother. I'd rather get 18cents a pound then deal with it. If its what I am thinking it is really smelly if you cut it with the angle grinder.
Need more information, and pics. Many electric motors have a hard coating, binding the windings together and hardening the string that also binds them, making them a huge PITA to work with. One the other side of the coin, I break down the electric motors out of many refrigerator and freezer compressors, as these do not have the same varnish binding the windings together, and the string is easy to remove. I have turned in several buckets of this as #2 copper, and the yards have not had any problems paying as such, even though each individual wire has a very thin coating of something or other.
