  1. 1. Control Aid Implementation -Modelling and simulation of triple extruder-

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Karl Langsér; [2023]
    Nyckelord :Machine Learning; Extruder; Modelling; Simulation; Extreme learning machine; Chemical engineering; Technology and Engineering;

    Sammanfattning : In the production of their High Voltage Direct Current Cables (HVDC) and High Voltage Alternating Current Cables (HVAC), NKT uses triple extruders to create layers of insulation and semi-conduction. A model to predict the effect of extruder inputs on the cable’s insulation and semi-conducting layers has been created and trained to predict the extruder in discrete time. LÄS MER

  3. 2. Undersökning av möjligheter att förse en kundparkering med laddstationer för elbilar

    M1-uppsats, Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

    Författare :Simo Ouallou; Steven Yakob; [2021]
    Nyckelord :Laddbara fordon; klimatmål;

    Sammanfattning : För att nå klimatmålet och minska koldioxidutsläppen har elektrifiering av transport och försäljning av laddbara fordon ökat snabbt de senaste åren. För att möta utvecklingen måste en tillgänglig laddinfrastruktur förberedas. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

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

    Sammanfattning : 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. LÄS MER

  5. 4. High-Frequency Voltage Distribution Modelling of a Slotless PMSM from a Machine Design Perspective

    Master-uppsats, KTH/Elkraftteknik

    Författare :Patrik Brauer; [2018]
    Nyckelord :Windings; drives; transients; surges; steep-fronted; slotless; litz-wire; effective relative permeability; Lindningar; elektriska drivlinor; transienter; spänningspulser; litz-tråd; effektiv relativ permeabilitet;

    Sammanfattning : The introduction of inverters utilizing wide band-gap semiconductors allow for higher switching frequency and improved machine drive energy efficiency. However, inverter switching results in fast voltage surges which cause overvoltage at the stator terminals and uneven voltage distribution in the stator winding. LÄS MER

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

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

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

    Sammanfattning : 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. LÄS MER
