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

    Författare :Erik Lindberg; [2023]
    Nyckelord :Variable speed drives; Sensorless control; Luenberger observer; Synchronous reluctance machine; Permanent magnet synchronous machines; Vector control; Model reference adaptive system; Variabel hastighetsreglering; Sensorlös reglering; Luenberger observatör; Synkron reluktansmaskin; Permanentmagnetmaskin; Vektorreglering; Adaptiv modelreferensreglering;

    Sammanfattning : Energy efficiency in electric machines is both environmentally and economically important. Water pumps with an integrated Variable Frequency Drive (VFD) and a Permanent Magnet Synchronous Machine (PMSM) have challenged the status quo of the Induction Machine (IM) for water pumps. LÄS MER

  3. 2. Powertrain of heavy electric vehicles: : Analysis of the production chain and impact on environment and industry

    Master-uppsats, KTH/Energiteknik

    Författare :Svenja Gelpke; [2018]
    Nyckelord :;

    Sammanfattning : Elektrifiering av bilar och mindre transportfordon pågår och flottaaktier ökar men diskussionen om elektrifiering av långdistanstransport är relativt ny. Elektriska lastbilar som använder fossila bränslen och som produceras med förnybara energikällor är lovande, särskilt i länder med en ren elmix. LÄS MER

  4. 3. Design and comparison of PMaSynRM versus PMSM for pumping applications

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

    Författare :Viktor Briggner; [2018]
    Nyckelord :Demagnetization; economic evaluation; permanent magnet assistance; synchronous reluctance machine; Avmagnetisering; ekonomisk utv¨ardering; permanentmagnetassistans; synkron reuktansmaskin;

    Sammanfattning : This master thesis aimed to design a permanent magnet assisted synchronous reluctancemachine (PMaSynRM) rotor for pump applications which were to be implemented inan existing Induction Machine stator. The machine were to be compared with a similarpermanent magnet synchronous machine (PMSM) with similar torque production in termsof cost and performance. LÄS MER

  5. 4. Simulation of an Electrical Machine : with superconducting magnetic bearings

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Mesut Bahceci; [2015]
    Nyckelord :induction motor; superconducting bearings; air-gap;

    Sammanfattning : This master thesis investigates if there is an induction motor configuration that can be used with a flywheel energy storage system, that uses passve superconducting magnetic bearings (SMBs). The configurations should be able to be designed with induction motor building blocks that are commercially available. LÄS MER

  7. 5. Design of a Synchronous Reluctance Motor Assisted with Permanent Magnets for Pump Applications

    Uppsats för yrkesexamina på avancerad nivå, KTH/Elektrisk energiomvandling

    Författare :Adrian Ortega Dulanto; [2015]
    Nyckelord :Demagnetization study; efficiency; FEM; parametric study; Permanent-Magnet Assisted Synchronous Reluctance Motor; prototype;

    Sammanfattning : This Master thesis focuses on the design of a high efficiency Permanent-Magnet-Assisted Synchronous Reluctance Motor (PMASynRM) intended for pump applications. The new motor is designed to replace an existing Induction Motor (IM) in a pump product. The basic principles of SynRM, and PMASynRM Motors and a good analytical model were introduced. LÄS MER
