You have an interesting deal.

Isn't the copper very hard to remove in the big industrial motors? At least all the ones I've seen are heavily impregnated with varnish and even epoxy. They aren't coming out without a fight. I guess if you pull the stator out of the motor frame you can cut off the ends of the windings and get copper coil price for it.
Is you employer in the motor rewinding business? Cause they will have an oven to burn off the guck out of the windings so they can remove the old wire. Maybe you can get use of it...
Don't forget to have a good look at the rotors. The big motors sometimes have copper bars in them, or big chunks of aluminum that can be broken off the rotor.
Good luck!!
Jon.
