    Abstract : In this master thesis, the magnetic properties of SiFe laminations after cutting and welding are studied. The permeability and the iron loss density are investigated since they are critical characteristics for the performance of electrical machines. READ MORE

  5. 4. Further development of a pulse magentizer

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Jon Axelsson; Per Söderberg; [2012]
    Keywords : Technology and Engineering;

    Abstract : A machine for magnetizing permanent magnets is under development at LTH. The idea of the machine is to affect only small pieces of a magnet at the time to obtain magnets with an arbitrary flux density, of course with respect to the magnetic material. The final machine is supposed to work in a closed loop fashion. READ MORE
