  1. 1. Performance analysis of motor for electric aviation

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Torkel Svenson Hagström; [2020]
    Nyckelord :;

    Sammanfattning : With a rising interest and improving technology regarding electric aviation, the Swedish ELISE-project aims to built a functional 21-seated electric aircraft by the year 2025. The aim of this thesis is to analyze the performance of a scalable model of an electric motor optimized for aircraft, in terms of magnetic leakage flux, generated back-EMF, torque constant and efficiency.

  4. 3. Optimization of Line Start Permanent Magnet Synchronous Motor for Magnet Cost Reduction

    Master-uppsats, KTH/Elektrisk energiomvandling

    Författare :Amit Kumar Jha; [2012]
    Nyckelord :Line start reluctance motor; LSPM; magnet assisted reluctance motor; Magnet volume reduction; Optimization of LSPM;

    Sammanfattning : In this thesis different methods of optimizing line start permanent magnet motor (LSPM) for magnet cost reduction is studied. Influence of different parameters has been studied by simulating magneto-static and transient FEM models of the machine. Finally a motor design of a LSPM with high rotor saliency has been proposed.

  5. 4. Mätning av axiella magnetiska läckflöden i vattenkraftsgeneratorer

    Uppsats för yrkesexamina på avancerad nivå, Elektricitetslära

    Författare :Johan Nilsson; [2010]
    Nyckelord :Vattenkraft; generator; läckflöden; induktion;

    Sammanfattning : This thesis describes a method of measuring axial magnetic leakage flux in an operational hydropower generator. Axial magnetic leakage flux is the magnetic flux at the ends of a rotating generator, which goes through the stator parallel to the rotor axis. LÄS MER
