  1. 1. Mapping of IPM machine efficiency and Noise Vibration Harshness : An investigation into trade-offs with respect to efficiency and Noise Vibration Harshness

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

    Författare :Bix Eriksson; Erik Rudqvist; [2023]
    Nyckelord :;

    Sammanfattning : Due to the recent shift towards electrification, electric machines has become a prominent option to be used in vehicle applications. Much effort is spent in the development process of these machines to make optimizations in order to improve the performance aspects of the machine. LÄS MER

  3. 2. Increased Displacement in Magnetomotive Ultrasound Imaging by Adding a Homogeneous Magnetic Field

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Jules Reniaud; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Magnetomotive Ultrasound, MMUS, is an imaging modality used to reveal a magnetic contrast agent using an external time-varying inhomogeneous magnetic field. By this, the particles are set in motion, and the motion is detected with ultrasound. LÄS MER

  4. 3. Comparison of FOC and DTC in an application of a screw joint emulator

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

    Författare :Axel Fyreskär; Joel Greberg; [2020]
    Nyckelord :;

    Sammanfattning : Atlas Copco produces, among other things, tightening tools for screw joints. The purpose of these fastening elements is to produce a clamping force between two parts, holding them together. LÄS MER

  5. 4. Implementation and experimental evaluation of a parameterized PMSynRM model using Matlab and Comsol Multiphysics

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

    Författare :Israt Jahan; [2019]
    Nyckelord :Comsol Multiphysics; eddy-current losses; permanent-magnet synchronous reluctance motors; reluctance; Comsol Multiphysics; virvelströmsförluster; permanentmagnet synkrona reluktansmotorer; reluktans;

    Sammanfattning : This thesis focuses on modelling of the permanent magnet synchronous reluctancemotor (PMSynRM), which has drawn considerable attention by researchers thanks toits high efficiency and wide range of speed operation. Comparisons with measurementsfrom a four-pole PMSynRM with four barriers and 24 stator slots have been carriedout. LÄS MER

  7. 5. Microstructure and Magnetic Properties for Mn-Al based Permanent Magnet Materials

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

    Författare :Axel Nyberg; [2017]
    Nyckelord :;

    Sammanfattning : Manganese-Aluminium is an alloy with attractive ferromagnetic propertieswhenL10-structured ( -phase). If sucient permanent magnetic propertiescan be achieved at a low cost, it has potential to be a new permanentmagnet material on the market. LÄS MER
