As one of the most reused materials in industrial operations, electric motor scrap comes in different types, all of which have unique attributes and valour. Knowing these types helps industries who use electric motors to get value from their obsolete components.
Copper Windings Scrap
Copper windings scrap is the major part harvested from electric motors. The reason copper is known as the gold of electrical materials is because it allows the easy flow of electricity. Often, when motors break down, the windings or coils inside them are still okay. They either extract the copper, sell it as copper windings scrap, or process the copper for reuse in making other products.
Aluminium Scrap
Some electric motors have aluminium windings instead of copper. Although not as conductive as copper, aluminium is still widely used because it is lighter and way cheaper. When these aluminium windings or components get damaged, they serve as aluminium scrap that can either be sold directly or recycled into new aluminium products.
Steel Scrap
Steel is an important element used in the manufacturing of electric motors, especially the outer casing and the core. The magnetic layers of the stator and rotor are made using steel. Individuals get steel scrap from parts of the motor that get damaged or are no longer in use, or they recycle old steel components into new products.
Permanent Magnet Scrap
Some electric motors, especiallyDC motorsand brushless AC motors incorporate permanent magnets. These magnets are commonly made from neodymium, samarium-cobalt, or ferrite materials. When such magnets get damaged, they become permanent magnet scrap with considerable worth because these materials are not easy to find and high in demand.
Insulation Materials Scrap
Electric motors have insulating materials like varnish, resin, and other types of synthetic fibers. While such materials are not as valuable as copper or steel, they can still be recycled, or if they are in poor condition, sold as insulation materials scrap. Another option for insulation materials apart from recycling them is using them for lower-end products or packaging purposes.
Once electric motor components get worn out or are not in use, it doesn't mean they've come to their end. Many electric motor scraps find usefulness in a variety of industrial applications, especially in manufacturing and construction sectors, while some create new products altogether.
Recycling for Raw Materials
A good percentage of electric motor scrap are recycled to obtain raw materials, thus, a cost-efficient and sustainable alternative. Copper, for instance, extracted from scraps is repeatedly used to meet the large needs of the electrical and construction industries without hurting our planet by extracting more copper. Steel from old motors is melted and reshaped into new steel products, like construction materials, car parts, and industrial machinery.
Wind Turbine Generators
Electric motors that have copper windings can be used in the production of a permanent magnet synchronous generator used in wind turbines. This helps reduce the need for virgin materials and decreases the environmental impact of the wind energy systems.
Automotive Industry
Steel parts from electric motors can be used as inserts in automobile composites, thus, reducing the weight of the vehicle and increasing the fuel efficiency. Also, some components of electric motors, like the rotors and stators, find usage as magnet assemblies in hybrid and electric vehicles.
Renewable Energy Systems
Some scraps of permanent magnets from electric motors can be repurposed into devices that help generate solar power. For instance, they can be used to manufacture permanent magnetic generators that are integrated into solar tracking devices and improve the performance of the solar energy system.
Appliances and Consumer Goods
Minor components from electric motors, like bearings, shafts, and housings, get reused in making appliances like fans, blenders, and vacuums. Additionally, copper and aluminium windings are sometimes used in the production of jewelry, artworks, or electronic components like circuit boards.
Scrap electric motors can be used in multiple ways within the construction development and manufacturing areas and even create new products. Below are the most common ways electric motor scraps are repurposed.
Art and Creativity
Several artists and craftsmen seek after electric motor scraps for their next projects. Be it copper windings made into sculptures or steel casings as part of an industrial art piece, electric motor scraps help create unique products that serve as art or functional decor, all while promoting sustainability.
DIY Projects
Amateur electricians and makers reuse electric motor scraps for various DIY projects. Winding scraps can be utilized to make small motors, generators, or other electronic components. Motor casings can be transformed into tool organizers, plant holders, and even DIY speakers. This way, they don't only find new purposes in these old parts but also resonate the hard work put into each creation.
Educational Purposes
Electric motor scraps are sometimes used in vocational training programs where students learn about motor mechanics, electrical engineering, and recycling. Deconstructing these old motors provides students with hands-on experience that they wouldn't otherwise get, plus, it helps them understand the importance of sustainability in contemporary technology.
Lower-End Consumer Products
Some insulation scraps and components that are of lower value can be used together to manufacture inexpensive consumer products like toolkits, household items, or even some components used in musical instruments. While these products may not directly bring profit to the motor industries, they still help ensure that nearly every part of an electric motor has some form of utility beyond its initial purpose.
Craft and Handmade Products
Aluminium and copper scraps from electric motors are used by many small-scale entrepreneurs in the jewelry and craft industry. From vintage looking copper wires in necklaces to aluminium parts in home decorative items, these scraps are transformed into fashionable products with a promise of environmental preservation.
