I have found on some motors it was fairly easy to remove the copper wire (windings). Does anyone know what kind of wire yards consider this kind of copper?

Sometimes it's coated aluminum. Always do a scrape test.

Trust the government? Ask an Indian. |

"Sometimes it's coated aluminum. Always do a scrape test."
I found that out on one of the first ones I took the windings off. It did not look right and felt too light, so I took a magnifying glass and looked at the ends I cut, and found that there were aluminum windings along copper windings. I learned to cut the windings and look at the ends.

| Keep in mind as you look at these motors that the aluminum windings always seem to be thicker than the copper ones. If they look thick, scrape it. |

| I actually found the opposite to be true on the windings I removed. The aluminum ones seemed to be thinner. These are from compressors from refrigerators. I have found that many of the refrigerator compressors do not have that coating of shellac or whatever it is that makes the string so hard to cut and remove from the windings. It also "glues" the individual winding strands together, and again makes them harder to remove. If I find them I now do not bother trying to remove the windings, but still save them and sell them as electric motor scrap (which is still better than tin). |

| If you can heat the moter , cut one end of the winding off with a long chisel flip and clamp , pry the windings out with a long round screwdriver. it can go easy, the varnish smell is not very appeling to inhale |

| That is pretty much what I do now as long as there is not a varnish coating. The string is easy to cut, and can pretty much pull it off intact. Then I cut one end of the winding and pry with a screwdriver. I did not find a need to heat the motor. The ones that have the varnish coating are also recessed in the motor housing, and are a pain to get to everything (string, wire, etc). These again I leave as is and sell as electric motors. So far it has been worth it to remove the windings, as I have a 5 gallon bucket full of them. |
