Recycling Electric Motors as Source of Raw Materials

07.12.2011
Led by Siemens, a consortium of partners from industry and research are developing solutions for recycling electric motors. The consortium is focusing on permanent magnets, which contain a high proportion of rare earth metals and are needed for electric and hybrid vehicles.

In their efforts to develop a solution suitable for application in industry, the partners in the MORE (MOtor REcycling) project are taking into account all links in the value chain — from design and production of motors to retrologistics to reuse in vehicles. The project is being funded by Germany’s Federal Ministry of Education and Research (BMBF).


Permanent magnets with a rare earth metals content of 30 percent are needed for compact, lightweight synchronous motors. Demand for rare earths will rise sharply in the coming years — due to increasing production of electric and hybrid vehicles, to name one reason. On the one hand, China has monopolized the supply of rare earths, so supply shortages can be expected. This is why the BMBF is promoting, among other things, development of resource-conserving technologies for electric vehicles with its “Key Technologies for Electric Mobility” (STROM) initiative.

The researchers working on the MORE project are taking various approaches to electric motor recycling: removal of the roughly one-kilogram magnet from scrap motors, repair and subsequent reuse of the electric motor or its components, and reuse of the magnet materials and raw materials, and the rare earth metals, following their extraction from pre-sorted and shredded materials. Also being developed are concepts for a recycling-compatible motor design, as well as ecological efficiency analyses and models for material cycles.

The results of the project are scheduled to be presented by 2014. The participating experts are from Siemens, Daimler, Umicore, Vacuumschmelze, the University of Erlangen, the Clausthal University of Technology, Oeko-Institut Darmstadt, and the Fraunhofer Institute for Systems and Innovation Research ISI. In the future, the technologies developed during the project could be used for applications in other fields in which rare earths play a key role, for example in wind turbines.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
