How much copper is in an electric motor?

2026-07-08

Range of copper content in electric motors

The copper content of an electric motor is approximately 8–10% of its total weight. For example, from a 100-kilogram motor, approximately 8–10 kg of copper can be recovered. This estimate is based on the generally accepted range of copper content within the industry. As a key component of electric motors, copper plays a vital role in heat and electrical conductivity. The copper content of a motor depends on several factors, including size, model, specifications and power rating.
 

Copper Content in Motor Recycling

Specialised recycling reduces unit costs through large-scale processing. For example, dismantling one metric tonne of end-of-life motors yields 0.6 metric tonnes of copper, 0.2 metric tonnes of aluminium and 0.1 metric tonnes of iron. Metal recovery rates can exceed 96 per cent. Compared to traditional landfill or incineration, this method reduces carbon dioxide emissions by 80 per cent and prevents heavy metal contamination of the soil. The use of specialised electric motor recycling machines enables the efficient recovery of copper from motors. With a motor stator copper extraction machine, the purity of the recovered copper can reach over 99 per cent.

Recovery and Reuse of Copper from Electric Motors

Understanding the copper content of electric motors not only helps to assess their performance and value but also provides a crucial basis for the recovery and reuse of copper resources. With the growing global emphasis on sustainable development, the recovery and reuse of copper from electric motors has become a trend. This not only helps to reduce dependence on limited copper resources but also lowers production costs and minimises environmental pollution.
