Electric Motors
Copper-wound electric motors from appliances, HVAC, and industrial equipment, containing copper, steel, and aluminium in proportions that make them consistently valuable scrap.

History & Interesting Facts
The electric motor was invented by Michael Faraday, whose 1821 demonstration of electromagnetic rotation was the first practical step toward motors as we know them. By 1837, commercial DC motors were powering early industrial machinery. Nikola Tesla's development of the induction motor in 1887, which runs on alternating current without brushes or commutators, established the design that still accounts for the vast majority of motors produced today. The 20th century saw electric motors penetrate virtually every corner of industrial and domestic life: factory machinery, domestic appliances, HVAC systems, pumps, fans, compressors, and automotive accessories. A typical UK home contains 20–30 electric motors, from the washing machine drum to the refrigerator compressor. Modern industry is almost entirely motor-driven. The copper windings at the heart of these motors represent a valuable, recoverable resource when the motors reach end of life.
Historical Uses
Electric motors transformed industry and domestic life through the 20th century. Factory electric drives replaced steam shafting systems, enabling more flexible, safer, and efficient manufacturing. Domestic appliances, washing machines, refrigerators, vacuum cleaners, and food mixers, brought electric motor technology into every home. Lifts and escalators use large electric motors for safe, efficient vertical transport. HVAC systems use motors in fans, compressors, and pumps. Water supply and sewage treatment depend on motor-driven pumps for distribution and treatment. Railway traction motors power electric trains including the UK's InterCity 125 and modern Pendolino fleets. The automotive industry uses dozens of motors in each modern vehicle, window motors, wiper motors, fuel pump motors, and ABS actuators. Each of these applications generates scrap motors at end of life.
Current Uses
Scrap electric motors are purchased by weight at scrap yards and then processed either by specialist motor dismantlers or by smelters who extract the copper windings. Whole motors command a lower price per tonne of copper than stripped winding copper because of the steel and aluminium content. Motor dismantlers burn off winding insulation (using controlled burning processes permitted under Environment Agency licensing), then sell the exposed copper stator windings, "electric motor wire", as a copper product at prices near dry bright wire grade. The steel laminations (the core of AC motors is built from thin silicon steel stampings) are sold as electrical steel scrap, a premium ferrous scrap used in transformer and motor core production. Aluminium motor housings are sold as cast aluminium scrap. Large motors from industrial plant can be economically stripped by hand for maximum copper recovery.
Future Possible Uses
Electric motors are central to the net-zero transition. As internal combustion vehicles are replaced by battery electric vehicles, each EV contains one or more traction motors with significant copper windings, generating new motor scrap streams as EV drivetrains eventually reach end of life. Industrial motor efficiency regulations (the EU IE4/IE5 minimum efficiency standards, mirrored in the UK) are driving replacement of millions of older, less efficient motors with new high-efficiency versions, generating scrap motor volumes that will increase through the late 2020s. The UK's net-zero heating transition will add heat pump motors (highly copper-intensive compressor motors) to the future scrap stream. Wind turbine generators are large copper-wound machines, decommissioning of the UK's first-generation offshore wind farms (built from around 2002) will yield substantial turbine generator scrap.
Where Does This Scrap Come From?
Electric motor scrap arises from domestic appliance replacement (washing machines, dishwashers, fridges), industrial plant decommission and upgrade, HVAC system replacement in commercial buildings, vehicle dismantling (alternators, starter motors, wiper motors), and workshop machinery replacement. Electrical rewind shops that repair industrial motors accumulate damaged stator windings removed during repairs, this burnt or damaged winding copper is a consistent scrap source. Scrap dealers and waste management companies recover motors from mixed commercial waste. Pump repair companies decommission irreparable pump motors. Data centres replacing cooling systems contribute fan and compressor motors. The motor should be free from non-metallic attachments where possible, rubber mountings, capacitors, and terminal boxes should be removed to achieve the best price per tonne.
How Is It Remanufactured?
Electric motors arriving at scrap yards are purchased by weight and either sold whole to specialist processors or dismantled on-site. Specialist motor processors use de-lacquering ovens or controlled burning to remove winding varnish, then shake out the copper windings from the steel laminated core. The copper windings ("electric motor wire") are sold to copper smelters, the insulation has been removed and the copper is relatively clean, commanding prices between 60–80% of bright copper. Steel laminations are sold as electrical steel scrap, which commands a premium over general steel because of its silicon content and thin-gauge form. Aluminium housings go to aluminium smelters. The multi-material recovery approach maximises total value per motor. Large motors are sometimes remanufactured, the windings re-insulated and re-varnished, rather than scrapped, extending their service life.
5-Year Price Trend & Forecast
Whole electric motor scrap prices are driven by copper content (typically 10–15% of total motor weight for small motors, up to 30% for large industrial motors) and the relative prices of steel and aluminium. Over 2021–2026, as copper prices rose strongly, the value of motor scrap increased proportionally. UK scrap yard prices for whole electric motors have ranged from approximately £300 to £800/tonne over this period, reflecting the blended value of all metals. Stripped motor winding copper commands near-bright copper prices (minus the stripping cost). Large industrial motors with known high copper content are sometimes valued individually rather than by weight. The long-term outlook for motor scrap values is positive: EV traction motor scrap will eventually be a significant new stream, and the copper content of modern high-efficiency motors is higher than in older designs.
