What metals are used in electric motors?

What type of wire is used in electric motors?

The most common magnet wire is copper insulated wire used in electric motors – one of the greatest inventions of all time, right up there with the wheel and light bulb. Magnet wires can be divided into broad categories that include enameled wire, covered (or served) wire, or combinations of the two.

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.

How much copper wire is in an electric motor?

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.

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.

Can you scrap electric motors?

The electric motor will probably have Insulated Copper Wire connected to it. You can take wire cutters and snip them to remove them from the motor. You can place the wire in your copper wire pile for scrap. Once you have the electric motor removed from your item, you can add them to your pile of electric motors.

Is copper wire worth more stripped?

Four-Strand Phone Wire Stripping Potential

With the outer insulation removed, copper represents 59% of the total weight and is worth stripping further if you have a wire stripper.

How much are electric motors worth?

Most scrap yards, including Scrap Stop, offer a price for electric motors, so that you don’t have to worry about dismantling at all. This price changes based on your region and over time but the current price for electric motors is around 15 cents per pound*.

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 do you calculate the weight of copper in a motor?

The copper weight is calculated by the cross section of a cable x 9.6 and will be shown in kg / km. For example FLRY 1.50 mm² has a copper weight of 14.4 kg / km (9.6 x 1.5).

What does an electric motor need in order?

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.

What is electric motor with diagram?

An electric motor is a device that converts electrical energy into mechanical energy. Diagram: Electric motor. Working of an electric motor: An electric motor works on the principle of magnetic effect of electric current. In an electric motor, a rectangular coil ABCD in placed between two magnets in poles N and S.

What are the four parts of an electric motor?

Motor Components

The components of an electric motor may include a rotor, thin sheets of stacked metal called laminations, a stator, wire windings, magnets, a commutator, brushes, poles, electrical interconnects and a housing.
