Copper in electric motors

The European annual motor market (all motor sizes) is 15 M units with an average copper content of 5.3 kg/unit. Annual copper use in this market is 79 ktonnes. This figure is expected to increase because of 2 drivers:

  • Increased efficiency, which in general leads to higher copper use, leading to copper use of 6.5 kg/unit (~ 20% increase)
  • Growth in the market to 20 million units per year, due to motorisation following electrification.

Hence copper use in the future EU motor market can be expected to be 130,000 tonnes per year, an increase of more than 50 ktonnes from today. Over the period 2018-2050, this leads to a an additional use of 1.5 M tonnes (50 k * 30 years). Considering that the average motor lifetime is around 15 years, and that copper in motors has an almost full collection and recycling rate, the demand for primary copper is half this amount, i.e. 750 ktonnes.
