  1. 1. Competitor analysis of the synchronous machines market : A study of how manufacturers differentiate themselves from each other with unique value propositions

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Fredrick Fager; Jiyan Kösanlioglu; [2023]
    Nyckelord :Synchronous machines; synchronous motors; synchronous generators; competitor analysis; value proposition; Synkronmaskiner; synkrona motorer; synkrona generatorer; konkurrentanalys; värdeerbjudande;

    Sammanfattning : This report highlights the market for synchronous machines and examines the current situation. Today, the world demands higher volumes of electrical power that is cleaner, more efficient and generated from fossil-free sources. This increases the importance of using efficient and modern that minimise energy losses. LÄS MER

  3. 2. Thermal Modelling of Permanent Magnet Synchronous Motor Windings in Heavy-Duty Electric Vehicles
