4. 3. Design of a Permanent Magnet Synchronous Generator with Alnico Magnets

   University essay from Uppsala universitet/Elektricitetslära

   Author : Fausto Lopez Gomez Partida; [2019]
   Keywords : Permanent magnets; Permanent magnet synchronous generator; Alnico;

   Abstract : Following the trends to diminish the fossil fuel energy production new technologies known for their renewable sources have become a signficant option for helping combat climate change and handle the current oil prices. These new technologies base their power production on already established physical principles that convert mechanical power to electrical power. READ MORE

5. 4. End-Of-Life Wind Turbines in the EU : An Estimation of the NdFeB-Magnets and Containing Rare Earth Elements in the Anthropogenic Stock of Germany and Denmark

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Lisa Welzel; [2019]
   Keywords : rare earth elements; neodymium; dysprosium; wind turbines; permanent magnets; recycling; recovery; closing the loop; urban mining; sustainability; sällsynta jordartsmetaller; neodymium; dysprosium; vindturbiner; permanenta magneter; återvinning; cirkulärt system; hållbarhet;

   Abstract : Securing rare earth elements (REE) for a stable supply require sustainable management strategies in Europe due to a missing local primary production and a dependence on China as the main producer of REE. These elements, like neodymium (Nd) and dysprosium (Dy), are contained in permanent magnets (PM) (mostly NdFeB-magnets) in wind turbines. READ MORE
