The copper content varies among different types of motors, while small motors have a higher percentage of copper per weight than heavy motors. On average, fractional electric motors are 9-10 percent copper by weight. AC motors average 7-9 percent copper; DC motors have 15-18 percent copper content.
What grade of copper is in electric motors?
The main grade of copper used for electrical applications is electrolytic-tough pitch (ETP) copper (CW004A or ASTM designation C11040). This copper is at least 99.90% pure and has an electrical conductivity of at least 101% IACS. ETP copper contains a small percentage of oxygen (0.02 to 0.04%).
How much is a electric motor worth for scrap?
electric motor and it is worth $0.15 per lb in scrap (prices vary of course depending on market demands, etc.) which means that motor is worth $1.50 as-is.
What metals are in electric motors?
Powder metal components for motors generally consist of iron, nickel, and cobalt.
- Iron is the cheapest of the three, so many designers tend to turn to there first.
- Cobalt is rarely used on its own, but is sometimes added to iron. …
- Nickel is expensive but valuable to motor applications.
What is the difference between bare bright copper and #1 copper?
Bare Bright Copper
It refers exclusively to bare, uncoated and unalloyed wire or cable – no thinner than 16 gauge in thickness – which is of #1 copper quality. … This includes any visible oxidation, and very negligible amounts of patina on the copper are allowable.
Do scrap yards buy electric motors?

How much copper is in an alternator?
Since copper makes up less than 25% of the weight of an alternator…you do the math.
Why is copper used in electric motors?
The high conductivity of copper means that components can be made smaller and kept closer together. … Their efficiency can be improved using cast copper rotors – again because currents will flow so easily in copper. Electric motors are typically 85 to 95% efficient in transferring energy to their load.
What are the 6 parts of an electric motor?
These six components include:
- 1) The Rotor. The rotor is the moving part of your electric motor. …
- 3) The Bearings. The rotor in your electric motor is supported by bearings, which allow it to turn on its axis. …
- 4) The Windings. …
- 5) The Air Gap. …
