I have broken down a bunch of those motors. My yard pays .15 cents a pound for aluminum windings and .20 cents for copper windings. I took them apart and went to my scrap yard. I got the total weight of the motor iron and the aluminum and copper. I figured out I had made $30 dollars more for breaking them down verses turning them in whole. Probably did 20 to 30 motors. Not a good return for my labor. But I will still tear them down
