  1. 1. The Effect of Alternative Tungsten Carbide Grain Size Distribution on Microstructure and Mechanical Properties in Cemented Carbides

    Master-uppsats, KTH/Materialvetenskap

    Författare :Filip Ivarsson; [2022]
    Nyckelord :Cemented Carbides; WC Grain Size Distribution; Mechanical Properties; Microstructure Analysis; Hårdmetall; WC Kornstorleksfördelning; Mekaniska Egenskaper; Mikrostruktur Analys;

    Sammanfattning : In the constant pursuit of better-performing cemented carbides, recent studies suggest that a combination of better hardness and toughness can be obtained by changing its WC grain size distribution. As the area is still rather unexplored, this  thesis  aims  to  broaden  the  knowledge  and  answer  whether mechanical properties can be changed by changing the WC grain size distribution, in the context of mining drill bit inserts.

    Sammanfattning : When developing three-phase drives for Electric Vehicles (EVs), it is essential to verify the controller design. This will help in understanding how fast and accurately the torque of the motor can be controlled. LÄS MER

  4. 3. Power Electronic Stages for a TFPMSM in Wave Power Applications

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Gustaf Falk Olson; [2016]
    Nyckelord :transverse flux permanent magnet synchronous machine TFPMSM ; active rectifier; direct drive wave energy converter; feedback linearization; cascaded PID controller.;

    Sammanfattning : Direct drive wave energy conversion systems have been identified as a potentially major contributor to the world’s energy demands, forecasting shares of up to 25 % of the energy mix. Anders Hagnestål conducts research at the Royal Institute of Technology where a novel linear transverse flux permanent magnet generator is developed. LÄS MER
