  1. 1. Analytical Approach to Understanding the Tooth Height Variations of the Stator in an Axial Flux Machine and its Impact on the Airgap

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Louise Lövgren; [2019]
    Nyckelord :Stator; axial flux machine; Höganäs; Soft Magnetic Composites; SMC; Somaloy; flatness; tooth height; airgap; crimping; Technology and Engineering;

    Sammanfattning : Höganäs AB is developing an axial flux machine, where an even airgap between the stator and rotor is a vital parameter when designing a well functioning machine. It is believed that the stator is the component that introduces the biggest variations to the airgap, and that is why the stator is the object of investigation for this thesis. LÄS MER

  3. 2. Corrosion and protections of Somaloy® components

    Master-uppsats, KTH/Materialvetenskap

    Författare :Zhao Yu; [2016]
    Nyckelord :corrosion protection; soft magnetic composites; phosphoric acid coating; sodium silicate coating; DCA-Modified silicone conformal coating; water-borne single coat paint; salt spray test; TRS; hysteresis loop; EIS;

    Sammanfattning : Corrosion protection is very significant for metals in modern society from the view of industrial development. This thesis work project involves a research study that is aimed to investigate the effect of corrosion on the mechanical strength and magnetic properties of four no treated or treated Somaloy® component samples (Somaloy®700 1P,  Somaloy®700 3P, Somaloy®700HR 5P and Somaloy®110i 5P) provided by Höganäs AB and laminated steel sheets by salt spray test.

    Sammanfattning : Fe-based amorphous powders are fabricated through gas and water atomization using industrial grade raw materials. The atomic structure of the powder is examined by X-Ray Diffraction (XRD). LÄS MER

  5. 4. Magnetism of Nanocrystallized Amorphous Fe75B10Si15

    Master-uppsats, KTH/Materialvetenskap

    Författare :Arnab Chakraborty; [2012]
    Nyckelord :amorphous metals; nanocrystalline materials; magnetism; soft magnetic material;

    Sammanfattning : Amorphous ribbons of alloy composition Fe75B10Si15 are cast by melt spinning and annealed to partially nanocrystalline states. The magnetic properties are investigated by VSM and MTGA. Structure is examined using XRD and SEM. LÄS MER

  7. 5. Synthesis and Characterizations of Fe-based Metallic Glassy Systems

    Master-uppsats, KTH/Materialvetenskap

    Författare :Zulfiqar Hussain Shah; [2011]
    Nyckelord :melt spun ribbon; soft magnetic properties; crystallization; Curie temperature; electrical resistivity;

    Sammanfattning : This thesis is a study of tailoring amorphous Fe-B-Si based alloy to produce bulk glassy rods by adding Nb. We have prepared rapid quenched thin ribbons (thickness ~12 µm) by melt spinning, and glassy rods of diameter ~1mm by Cu-mold casting based on compositions (Fe0.78B0.13Si0. LÄS MER
