    The motors I have pulled apart are from pool pumps. The weird thing was that the copper windings were not copper. It looked like an aluminum winding with a varnish on it. I am still a noob, but I take it is not the same thing right?

    If you can, reach in a snip a strand and if it's alum. in the middle then leave the motor intact and sell as is. If it's copper then you have a choice to sell as is or retrieve the copper.

    Yes very informational thanks. I have been tearing up appliances lately for the moters. (one of them being a thrift store heater I got for Christmas.) I turned it on for the first time went to sleep and felt for some reason to wake up and saw it was on fire.) And it is suprising how many things have moters.

    I have found that it is not profitable enough to break down motors and such for copper, based on return. I do not even separate motors out. I’m small scale so others may have different options/opinions. Shred price vs motor price vs copper price vs time........only you can decide . And learn.

    I want to update the pricing as follows:

    Price from the original post -

    So it started out at 27.8 LBS at $.41/lb = $11.40
    Broke down we had 3.5 lbs of copper at $3.50/lb = $12.25
    .25 lbs of cast alliminum at $.52 = $.13
    24 lbs of steel at $.10/lbs = $2.40
    Total after tear down is $14.78 for a difference of $3.38

    Price today - (actually price is from a few months ago, and may vary by location)

    So it started out at 27.8 LBS at $.12/lb = $3.33
    Broke down we had 3.5 lbs of copper at $1.90/lb = $6.65
    .25 lbs of cast aluminum at $.12 = $.03
    24 lbs of steel at $.0365/lbs = $.87
    Total after tear down is $7.55 for a difference of $4.22

    Big difference between the two percentage wise. You can more than double your money now. (correct my math if I am wrong anywhere)

    Then:

    Total after teardown : 14.78 $

    Now:

    Total after teardown: 7.55 $

    It's the same amount of work for half the pay. Thanks for the update N.P.

    Wow??? Just read this post of yours from back in 2011. Might just be the single best tip i've read here since joining this forum! Using the oil from the compressors (or within the cut radiators) to "grease" and loosen the cooper windings, might just be the trick for a much easier task of removing the windings from all the electric motors I get. Thanks!!

    Most of those motors you have in photo are condenser fan motors. I find they are exposed to the weather more then the air handler and tend to be a bit harder to pull the windings out! This is where my "recycled" saved up compressor oil comes into play! I Like to " baste" them in a shallow dish with my saved up "marinade" after I cut the one side and find them being a problem. That make the copper slide out'athere like ..............

    Hope this helps!
