trying to dismantle motor for scrap

Its a motor from a washing machine. What is the best way to get it apart to liberate the wiring (and anything else of value) for scrap? Its about 7.5" from one end of the shaft to the other and about 4.5" across. I tried cutting through the plates that make up the bulk of the unit but stopped when progress was obviously very slow (photos 2 & 3). Im not sure what the metal the plates are made of, steel maybe?`Anyway, its worth more stripped down then whole. I wouldnt be doing this for just one, I have a bunch of them. Any suggestions?

I have more photos should that help.

Quite a job putting them together. Even harder to take a part.

The bulk of the motor is laminated steel plates. You wont be cutting them easily.
What about cutting thru the coils of the copper wire and then pull the wire out ?

Did you try a grinder and 1/16" blade?

PJmax, certainly sounds like an elegant solution. Are the plates worth wrestling with?

XSleeper, grind what?

The plates are useless and won't come apart with major cutting.

Personally, I think you'd make more going out and collecting aluminum cans, and get exercise at the same time. There's maybe a pound of copper in there, most of the weight is the steel. If they'll take it as is, use your time for something else.

here in NJ you get more more for a motor intact then you do for copper/iron. with motor as you show.....

If U look at the price difference after U separate it and labor spent you are losing....

I did that a couple of times when I was in my teens; I had to cut each and every wire on each side and then pull it out with a pair of pliers.

Last week when I took some scrap metal to the recycler I got $1.50 a pound for the copper and $0.025 (two and a half cents) per pound for scrap steel.

You could heat it to about 2000F and wait for the copper to drip out.

Maybe set it across the hollow of a cinderblock and sledgehammer the heck out of it? The big chunks will probably come apart.

You cannot unwind the coils of copper wire without first disassembling the steel plates of the field assembly. It takes a lot of work to cut the copper coils and pull out one turn at a time compared with unwinding.

Some motors have copper coils in the armature. You may be able to unwind these if you figure out the correct order (unwind the coil that was wound on last).

Scrap the whole motor as one unit,not worth the effort to strip the cu.

I agree with Geo, Scrap it out as a whole.

PJmax, that method worked quite well.

Not all the motors are the same so some got/will get stripped, other will be left whole. Once its all done, I'll report back on how I made out. Got 12 washers in the dumpster so far, got 8 more to go. Then theres lots of other ferrous and different non ferrous metals too.
