    How to strip copper from a constant motor

    I have two motors that are both "constant" motors. The copper running through them is wound around on either end....trying to come up with a good way to take it off. Typically, as I've seen in other threads, I cut the ends off and pull it through. This is wound around in such an odd way that that won't work. One of the motors is off of a fan, the other is off of a pump of some sort. Any thoughts?

    Some pics would help. I don't know about the pump but the fan motor you should be able to cut the copper off of one side and using a punch knock the copper throught and out the other side. I've done hundreds of fan motors like this with no problems.

    I'll try to get a photo. I know what you're saying, but I think this is different--its on a long spindle and is all wrapped around. I've never done a photo so I'll give it a try!

    Here are the photos. I've messed with these a couple of times and just can't seem to get the copper out. First picture is the casing of another similar motor. Second and third picture are different views out of the casing. Look at the third picture and how it is all wrapped around the spindle....any tips would be great!

    Yas, pictchers are worth a thousand words. i throw those in with my electric motors. I use to cut them in half on a band saw then you can punch the copper out the other end but I no longer have a band saw. If you find an easy way to get the copper out please let us know.

    Not an easy way, but I used to use a chop saw to cut one end off. With the price of copper down now, I also throw them in with my motors and concentrate on regular motors which are much easier to get the copper out.

    Thanks guys. I had three of these sitting around I just didn't feel like messing with. I got everything else broke down so decided to go back at it and just couldn't come up with a good way. Thought someone on here might have a better idea than I ever came up with! Oh well--my yard doesn't pay separate for motors, guess it will go in my shred pile. Maybe I'll mess with it and see if I can come up with something.

    Try to find a core buyer, they buy alot of car parts and batteries and such, they should buy electric motors and anything with copper it;s called copper brakage.

    yeah those are tough. I have even pulled the bearing off and driven the shaft out and still the best I could do is cut the copper ends off. If theres not an easier way I am not even going to mess with them

    I cut both ends off with a chop saw then i put it in a vice and hammer a screw driver into all the round holes. Works pretty well for me but some are easier then others. The ones that come out of carpet cleaners are a real pain cause most of the time they have some sort of residue all over the copper making it real hard and stiff. Takes me about 5-10 mins to do one. If im struggling with it for to long i just put it in my motor bin.

    I bash the insulation under the contacts with a hammer untill they come loose.
    Then I cut the loops off one end with a meat cleaver or angle grinder.
    Then I put the whole thing in a fire for a while to burn the insulation off, then dump it in cold water.
    Then I pick the windings out by hand.
    Done.

    Easy as pie. Hook a drill to it and spin it up. Then check with dvom to insure its putting out voltage. Youtube is full of how to videos.

    Funniest thing I found is a perpetual motion machine that I thought of year ago, but never patented. Everybody says it is against the law of physics, but you can make a genny that powers itself and puts out juice as well. All you need is one of these treadmill motors rrun by another electrical motor. Once the treadmill motor is putting out juice it will feed the motor juice that is spinning the treadmill motor. So essentially a perpetual motion/energy machine that is essentially free with no byproduct of smog or fuel used.

    Then leftover juice can be use to charge up a battery bank which you would run a Invertor off of. The possibilities are endless. Only thing i cant explain is why these are better at putting out juice compared to a everyday motor like in a pool pump.

    The videos are on youtube proving this theory solid which I had thought of many years ago. When everyone said perpetual machine was against the laws of physics. I honestly would say this is as close to perpetual motion as you get. A machine feeding itself with no maintenance.

    Hmm me thinks Im going to go build one. Funniest thing is Tesla probably had thought of these ideas, but his partner Edison stole all because he made it to the patent office before Tesla did. And tesla died a broke old guy in a apt with nothing while Edison died a millionare.

    Ponder this and I will get off my soap box. If history was changed and Tesla made it to the patent office before Edison, we would have wireless electricity flowing through the air with no wires. We would be able to turn a light bulb on anywhere in the world just by holding it. Hence the tesla coil which was a wireless energy experiment flowing through the air with no wire grid. Ponder that the wire grid is almost a 100 years and highly prone to fail at any moment while Tesla idea would prevent that

    Just imagine all the other ideas Tesla had, maybe even a perpetual motion energy machine like I have stated. And got lost in time. RIP Mr Tesla....the true father of electricity....:>

    Ozzy, when you try your experiment, let us know if it really works.
