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.

How much copper is in an electric motor?

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.

How much copper is in a 1hp motor?

2) Copper weight is @ 600gm per HP (+/-) 10%.

How much is an electric motor worth as scrap?

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 is the scrap rate of copper?

Questions & Answers on Copper Wires

Diameter Min Price Max Price
0.02 – 1 mm Rs 400/Kg Rs 600/Kg
1-3 mm Rs 450/Kg Rs 545/Kg
3-5 mm Rs 400/Kg Rs 700/Kg
5-7 mm Rs 460/Kg Rs 510/Kg

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).

How much copper is in a generator?

Copper in generators

Technology Average copper content (kg/MW)
Double-fed asynchronous generator (DFAG) 650
Conventional asynchronous generators (CAG) 390
Conventional synchronous generators (CSG) 330–4000
Permanent magnet synchronous generators (PMSG) 600–2150

How is motor winding calculated?

Call the number of turns N and the length l. Calculate the inductance associated with the winding using the formula L = (u0 * A * N^2)/l where u0 is the permeability of free space at 12.56 x 10^-7. If N is 100 turns, l is 6 meters and A is 7.069 square meters.

Does anyone buy old electric motors?

We buy electric motors, transformers, gear reducers and other electrical surplus. If you have used or unused surplus electrical equipment, call Jay Romanoff at 800-366-8778 or email to discuss the material you have for sale.

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.

How many pounds of copper are in a 10 hp motor?

These are not that easy to take apart and when you start to get all of your tools out you will have to take some serious time to do it. On average out of the 10lbs., the copper inside is only about 10-15% of the weight which would equal about 1.5 pounds.

What parts of an electric motor are copper?

What’s Inside an Electric Motor? The coil is made of copper wire, because copper is such an excellent conductor. It is wound onto an armature. The coil becomes an electromagnet when a current flows through it.

Why is copper used in motors?

Because of its high electrical conductivity, copper is commonly used in coil windings, bearings, collectors, brushes, and connectors of motors, including the highest quality motors. Copper’s greater conductivity versus other materials enhances the electrical energy efficiency of motors.
