Found a hydraulic motor in a trailer people leave things in them when they come back to get repaired . I scrub the floors they come back from construction sites. I have never seen a motor like this it's a dc motor like a sweeper but the copper is not stranded wire the middle part is thick like a romex the outer coils are some kind of flat copper usually it's stranded wire the motor weight is 17lbs I'm guessing lots of the weight is steel I'll post copper weight tomorrow. As is it would be 3.40$. .20 for electric motors.
