  1. 1. Fault Detection in Permanent Magnet Synchronous Motors using Machine Learning

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Alexander Lennartsson; Martina Blomberg; [2021]
    Keywords : PMSM; Fault Detection; AI; artificial intelligence; Machine Learning; inter turn short circuit; inter turn short fault; turn-to-turn; permanent magnet synchronous motor; short circuit; fault; avionics; airplane; aircraft;

    Abstract : In the aviation industry, safety and robustness are the number one priorities, which is why they use well-tested systems such as hydraulic actuators. However, drawbacks such as high weight and maintenance have pushed the industry toward newer, electrical, actuators that are more efficient and lighter. READ MORE

  3. 2. Excitation system – simulation, tuning and evaluation

    University essay from Uppsala universitet/Elektricitetslära

    Author : Philip von Heideken; [2021]
    Keywords : ;

    Abstract : Swedish Electrical and Power Control AB (Svea Power) offers excitation systems for electrical production plants. An excitation system controls the electrical performance of the generator’s three phase outputs and must meet requirements set out in the business agency “Svenska Kraftnäts (SvK:s) föreskrifter, SvKFS 2005:2”.

  4. 3. Directly Cooled Windings - Conjugate heat transfer assessment of air-cooled hollow conductor

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Michael Gabassi; [2018]
    Keywords : Conjugate heat transfer; hollow conductor; thermal management; direct cooled windings; heat transfer; electrical machines; Technology and Engineering;

    Abstract : The torque capabilities of electrical machines are today limited by magnetic saturation and the ability to transfer thermal loads away from the machine. A solution to thermal management in power turbo-generators involves hollow conductors allowing direct cooling of the heat source thus increasing the power density significantly. READ MORE

  5. 4. Improved Thermal Models for Predicting End Winding Heat Transfer

    University essay from KTH/Elkraftteknik

    Author : Gabriele Luca Basso; [2017]
    Keywords : ;

    Abstract : The thermal analysis is of primary importance for the design of any kind of electrical machine. The cooling has a significant impact on the electromagnetic performances and on the durability and reliability of the machine. READ MORE

  6. 5. Thermo-mechanical Fatigue of Electrical Insulation System in Electrical machine

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Ahmed Elschich; [2017]
    Keywords : Thermal mechanical fatigue; Thermo-mechanical stress; electrical machine windings; electrical insulation system; slot insulation; slot liner; groundwall insulation; conductor insulation; turn insulation; stator;

    Abstract : Electrical machines in electrified heavy-duty vehicles are subjected to dynamic temperature loadings during normal operation due to the different driving conditions. The Electrical Insulation System (EIS) in a stator winding is aged as an effect of these dynamic thermal loads. READ MORE
