My son-in-law does household repairs and I haul stuff away for him and then scrap it. Here is the thing, we get plenty of motors, both AC and DC, and we also get metal. It buys my tools. Now here is the question; what type of motors should I keep? I have a fabulous looking DC treadmill motor in my shed. I would rather keep things than scrap -- price differential. What ratings range should I watch for? In the past year I have tossed maybe twenty motors. This week I picked up two more from a washer and dryer.
