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. 4.
Is it worth scrapping electric motors?
Most electric motors are not worth dismantling for scrap. The copper content is usually not a high enough grade to justify the time it would take to separate from the other parts of the motor.
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 turn there first.
Are motor windings copper?
In most circumstances the motors are copper wound and could be worth more money if you wanted to take them apart, but sometimes they are wound with aluminum.
Is copper used in electric motors?
Copper is a major component in EVs used in electric motors, batteries, inverters, wiring and in charging stations. A pure electric vehicle can contain more than a mile of copper wiring in its stator windings.
What electric motors have the most copper?
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 is motor copper worth?

How many pounds of copper are in a electric motor?
On average out of the 10lbs., the copper inside is only about 10-15% of the weight which would equal about 1.5 pounds.
Why is copper used in electric motors?
Copper. … Copper is a great choice for motor windings because of its high conductivity and relatively low cost, but it is also a highly dense and heavy material; this is even more of a problem for motors used in electric vehicles or aircraft, which need to be lightweight.
Which motor is good copper or Aluminium?
Copper is stronger than aluminium. It expands less but both materials have a similar maintenance schedule. Copper can carry almost twice the current capacity of aluminium, which makes them slightly smaller in size than aluminium wound transformers.
Can aluminum replace copper in electric motors?
Due to the better connection to the laminated core and more favorable utilization of the installation space results in a much better thermal and electromagnetic behavior. For this reason, it is possible to replace wound copper coils with cast aluminum coils for improved performance and lower material costs.
How can you tell if winding is copper or Aluminium?
First, aluminum’s conductivity is lower than copper’s. To compensate, aluminum magnet wire must have larger cross-sections than the equivalent copper wire to offer the same conductance. This means windings wound with aluminum wire will likely have greater volume compared with an equivalent copper wire motor.
How much copper is in a Tesla motor?
There’s more than 50 pounds of copper in a typical U.S.-built automobile: about 40 pounds for electrical and about 10 pounds for nonelectrical components. The Tesla Roadster is also the first commercially available automobile powered by an electric motor powered by a copper rotor.
How much copper is in a Tesla?
While conventional cars have 18-49 pounds of copper, hybrid electric vehicles (HEV) contain approximately 85 pounds, plug-in hybrid electric vehicles (PHEV) use 132 pounds, battery electric vehicles (BEVs) contain 183 pounds, a hybrid electric bus contains 196 pounds, and a battery electric bus contains 814 pounds, …
Is copper a wire?
A copper wire is a single electrical conductor made of copper. … Copper has the lowest resistance to the flow of electricity of all non-precious metals. Electrical wiring in buildings is the most important market for the copper industry. About half of all copper mined is used to make electrical wire and cable conductors.
