  1. 1. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Muhammad Umar Farooq; [2023]
    Nyckelord :Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

    Sammanfattning : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces. LÄS MER

  3. 2. Automatic Recycling Sorting Unit: A platform designed to sort glass, plastic and metal

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

    Författare :Anni Li; Agnes Agåker Karlsson; [2023]
    Nyckelord :Mechatronics; Recycling; Inductive sensor; Capacitive sensor; Loadcell; Mekatronik; Återvinning; Induktivsensor; Kapacitivsensor; Viktcell;

    Sammanfattning : This report describes the design and construction of a tilting platform for sorting household waste, limited to plastic, glass, and metal. The platform utilizes a capacitive sensor to identify if an object is placed on the platform, an inductive sensor to detect metal, and a load cell to differentiate between plastic and glass based on their weight difference.

  4. 3. Hardware-In-the-Loop simulation of a small scale prototype of a Wave Energy Converter

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Anton Magnusson; [2020]
    Nyckelord :Hydrodynamics; Hardware-In-the-Loop; WEC-Sim; Wave Energy Converter; NEMOH; Hydrodynamik; Hardware-In-the-Loop; WEC-Sim; vågenergikonverterare; NEMOH;

    Sammanfattning : Renewable energy sources are a hot topic, both when it comes to climate change and the constant increase in demand of electricity due to population growth and a more electrified society. One such energy source is wave energy - an energy source with great potential but still relatively new with the need for further development. LÄS MER

  5. 4. Konstruktion av variabel last : Utvärdering av GPU:er genom simulerad flygfarkost

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Anton Schleu; [2020]
    Nyckelord :Design; aircraft; complex; GPU; 400 Hz; Konstruktion; flygfarkost; komplex; GPU; 400 Hz;

    Sammanfattning : När flygfarkoster befinner sig på marken får de sin strömförsörjning tillgodosedd genom att vara anslutna mot en GPU (Ground Power Unit), vilket förser flygfarkosten med spänningen 115 V till en frekvens av 400 Hz. Dagens moderna flygfarkoster består av mer avancerad elektronik, vilket kan ge upphov till störningar på den matande GPU som tidigare inte förekommit. LÄS MER

  7. 5. Compensating the Changing Reactive Power in the Medium-Voltage Grid in Stockholm

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Gabriel Nylander; [2020]
    Nyckelord :;

    Sammanfattning : A decline in inductive reactive power has been noted by several DNOs around Europe for the last decade. Why this is happening is unknown. One of the DNOs is the Swedish DNO Ellevio AB that has seen large decreases in demand of inductive reactive power from their primary substations. LÄS MER
