  1. 1. Evaluation of electric actuation for fighter aircraft

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Dennis Moliner Pettersson; Anton Nygårds; [2023]
    Nyckelord :EMA; actuator; actuation; MEA; aircraft; PMSM; SHA;

    Sammanfattning : The tendency of recent years towards electrification of aircraft components and subsys-tems has opened the door for a wider usability of electro-mechanical actuators (EMAs) inthat context. EMAs are already in use in aircraft industries but mainly in civil aviation forsecondary control systems and non-critical applications. LÄS MER

  4. 3. Omkonstruktion av bockverktyg : Från hydraulisk till elektrisk drivning

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Johannes Skarin; Anders Nygren; [2021]
    Nyckelord :actuator; battery; bending; cad; ctc; copper; finite-element; transformer; bockning; batteri; cad; ctc; finita-elementmetoden; koppar; ställdon; transformator;

    Sammanfattning : A hydraulic bending tool is used in the manufacturing of transformer windings at Hitachi ABB Power Grids. This tool is used to create a pitch between the turns in the winding, a process which demands very strict tolerances during bending. Hitachi/ABB believes that the current tool is quite inconvenient and, in some cases, dangerous to use. LÄS MER

  5. 4. Quantifying Middle Frequency Transient Currents in Power Consuming Devices

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Alex Lundvall; Vincent Sollie; [2021]
    Nyckelord :;

    Sammanfattning : The complexity of electrical systems present in vehicles is continuously rising and the number of interconnected electrical devices is growing during the strive for optimization and reaching higher efficiency levels. Actuation of said devices have the possibility of injecting voltage and current harmonics into the system, thus negatively affecting neighbouring devices. LÄS MER

  7. 5. Electrically powered manoeuvring of water jets

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Joel Engström; [2021]
    Nyckelord :Bachelor thesis; Thesis; Mechanical engineering; Uppsala University; Design; Product development; Marine Propulsion; Electrical Actuator; Water Jets; Water Jet Propulsion; Water Jet Manouvering; Steer-by-wire; Marine Technology; Examensarbete; Maskinteknik; Kandidatuppsats; Uppsala Universitet; Konstruktion; Design; Produktutveckling; Vattenjet; vattenjetaggregat; Elektrisk Manövrering; Steer-by-wire; Marinteknik;

    Sammanfattning : A shift towards electric and hybrid propulsion within the marine sector create new challenges for conventional water jet units manoeuvred by hydraulic systems. The high efficiency in high speed water jet crafts benefit from being powered by electricity but will be compromised by constantly running hydraulic pumps, draining available electric capacity on-board.
