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

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Jules Reniaud; [2022]
    Keywords : Technology and Engineering;

    Abstract : 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. READ MORE

  3. 2. Permanent magnet synchronous machine using ferrite vs rare earth magnets : how do they compare?

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Nikhil Manakshya; [2021]
    Keywords : Vehicle requirement; drive cycle; ferrite magnet; demagnetisation; environmental impact.; Fordonsbehov; körcykel; ferritmagnet; avmagnetisering; miljöpåverkan.;

    Abstract : Permanent magnet synchronous machines (PMSM are considered as viable options for automotive and traction applications. Rare earth magnets such as Neodymium Iron Boron (NdFeB is the most common choice in the PMSM for electric vehicles to achieve high power density machines. READ MORE

  4. 3. Cooling simulation of a BEV electrical machine rotor

    University essay from KTH/Fordonsdynamik

    Author : Lisa Sparv; [2021]
    Keywords : Electrical machine; Rotor cooling; Permanent magnet; Simulation; STAR-CCM ; Elmaskin; Rotorkylning; Permanentmagnet; Simulering; STAR-CCM ;

    Abstract : The thesis work described in this report is about simulation of the cooling of an electrical machine rotor. Limitations and simplifications were made on the CAD model of the rotor with the purpose of reducing the simulation time, for it to then be used for CFD-simulations using STAR-CCM+. READ MORE

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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. READ MORE
