That is alot of copper. That's more copper than what is in most people's house. Romex, they think Rome has the power but that's a different subject. I don't think that much copper is necessary, if that is a motor and you are trying to drive a stator or make a shaft spin in an electromagnetic field, I don't think you need that much. What you need is electricity for an electric motor and electro magnets in the housing for a motor. It's the electromagnetic field that turns the stator, it pushes from all sides causing the shaft to spin. It's not the amount of copper mounted in the housing, it's the wattage that is applied. 220 volts can produce only so much torque. 110 volts even less. Now if you had a higher voltage you could produce a higher torque motor. A high torque gm starter is very small with very little copper but will crank a v8 engine from a car battery. Now in a locomotive, diesel electric, you can power several high torque motors with a diesel generator and 3 million or more watt generator. The more electricity the higher the torque. You can build big electric motors but if you plug it in to a 220 system you will only get so much torque out it. We need to save copper, do more with less copper, more copper does not equal more power. Higher voltage equals more power even with much less copper on electric motors. There are ways we can find more copper mines using electricity with conductivity testing. I'm afraid these spirits have designed lots of products that cost more that waste resources. We need to really reexamine how things are engineered to make sure we are not wasting material. It's important. LLXIIX77
