   University essay from Stockholms universitet/Fysikum

   Author : Tim Melhus; [2021]
   Keywords : EBT-3; Gafchromic; Gafchromic EBT-3;

   Abstract : The Eu-XFEL, a 3.4 km long free electron laser situated in Hamburg, Germany was commissioned in 2017, and has since been at the forefront of cutting edge technologies. READ MORE

3. 7. Optimal Demagnetization of Transformer After Winding Resistance Measurements

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Niclas Grönström; [2020]
   Keywords : ;

   Abstract : In this thesis, transformer demagnetization in connection to winding resistance tests is investigated. In transformer testing, winding resistance measurement (WRM) is an important test used to detect winding or connection faults. It is common practice to measure the resistance by injecting a DC current into the windings of a transformer. READ MORE

4. 8. 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. 9. Design and comparison of PMaSynRM versus PMSM for pumping applications

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Viktor Briggner; [2018]
   Keywords : Demagnetization; economic evaluation; permanent magnet assistance; synchronous reluctance machine; Avmagnetisering; ekonomisk utv¨ardering; permanentmagnetassistans; synkron reuktansmaskin;

   Abstract : This master thesis aimed to design a permanent magnet assisted synchronous reluctancemachine (PMaSynRM) rotor for pump applications which were to be implemented inan existing Induction Machine stator. The machine were to be compared with a similarpermanent magnet synchronous machine (PMSM) with similar torque production in termsof cost and performance. READ MORE

6. 10. Thermal Analysis of a Sea Wave Generator

   University essay from KTH/Elkraftteknik

   Author : Ezequiel Quijada; [2017]
   Keywords : sea wave power generator; magnet overheating; demagnetization; heat transfer; conjugate heat transfer; thermal resistance; Comsol Multiphysics; cooling technique;

   Abstract : Wave power has been increasing the interest of many researchers looking for alternative sustainable energy sources since the reserves have proved to be capable of satisfying a considerable percentage of the world´s energy demands. This option has not been adopted as a sustainable source since there are some challenges in the process of designing a low cost device that converts the kinetic energy of the waves into electric energy and that could still be efficient enough to be competitive against other options.
