    took apart sealed entral air unit

    i pulled out the motor and it was mostly ali wire i got some copper off of it and left the ali wire on the motor will i get electric motor price even though its ali wire and not copper? lucky for me the copper wire was on the inside and the ali on the outside of the motor. i was wandering are all the a/c sealed units like this or are there some with all the wire being copper?

    With all of the fridge/freezer compressors I have scrapped. Only one has had Aluminium wires in it.

    Several large Aircon/heatpump compressors have had a mix of Ali/Copper wires and they all take 2-5 times the amount of work and grinder disc to get open.
    So I sell them as is. Its not worth the effort.

    I have taken apart probably a hundred sealed units, but virtually all fridge units. I tried one A/C compressor, and quickly found out they are not worth the hassle so all mine now get sold as is. The ones from refrigerators and freezers are much easier to cut open the sealed unit and to remove the wires.

    Use of a plasma cutter makes compressors mere childs play.

    For me the issue was not getting the A/C compressor unit cut open, it was easy with an angle grinder. The issue was getting the copper wires out with the heavy shellac/varnish coating on the wires and string. Too much of a pain.

    Understandable. I figured a way to use a log splitter to pull them, but realize it's not feasible or practical for everyone.

    I would love to see a pic of that. Any chance you would let us take a look at how you managed that, please? Is it toast as a log splitter or can it split logs AND press copper windings?

    Splitter still works for its intended purpose. I had bought it to try my hand at splitting stators. That didn’t work. So then I split a whole bunch of wood for my brother while I continued to day dream of what else I could use it for. One day I was looking at a motor with a cast housing. Previous attempts to shatter with a sledge proved futile. Got to wondering if it could break it. Cracked it like it was nothing.

    By wrapping a chain around the end of the beam and looping it around stator, I can pull windings with my frame clamp. I may tinker to see if I can cut a box tube to slide down over the end beam and use that instead of a chain. My primitive drawing hopefully explains what I am attempting to do.

    My log splitters a cheaper one, it has no power on the rearwards stroke, it uses springs to pull the ram back in. Its electric.

    But, by somehow fixing the stator against something on the logsplitter, I figured I could put the ram thru the stator and a steel rod thru the Copper wire end loops and push against the steel rod to push the Copper wire out.

    On the other hand, I'll probably never get around to actually doing it. And I lent the logsplitter out a while ago....

    Best to check. Use a file and see what color the wire is....

    thanks for the tip i kknow what the wire is i usually just cut it with the saw white shavings are bad and copper colered shaving good=) so if the motor has ali wire will it still be motor price even though its not copper?

    Depends on the yard. Around here yards buy alum and copper wound ones the same price.

    sorry to bring up the old tread but I was randomly clicking through stuff and just saw this. I just got into doing the compressors with a plasma as well. since some of them big ones were kind of testing my patience and destroying my vice I made a puller for em that I was gonna attach to a log splitter myself. I was only planning on using it for the bigger ones since the small ones come out easy enough by hand. Thank you for sharing. I was definitely over engineering this thing in my head.

    Dunno how I missed this post.

    I recently discovered a faster way of removing windings on the smaller motors. Pinch the wire in a vise, hammer stator off with air hammer/chisel.

    I only ran into one stator out of a sealed unit that gave me problems. It was from a A/C compressor that burnt out. It was a pain to remove the windings because the plastic slips melted to the copper and woundnt come out. Had to pound them out with a hammer and punch. All the other stators were easy cause of all the oil thats covering them. Only need a pair of wire cutters and a big screwdriver to do them.

    Probably did around 100 sealed units in my time scrapping.
