    Abstract : The electrification era has been marked up by an increase in volume of electric vehicles which are directly or indirectly powered by electricity. Railways, roadways and airways are being electrified as we speak at their own respective rate. READ MORE

  3. 2. Impact of Converter Modulation Strategies on the Losses in a Traction Motor

    University essay from KTH/Elektrisk energiomvandling

    Author : Emil Fjällström; [2015]
    Keywords : Induction Machine; FEM; FLUX; Induktionsmotor; FEM; FLUX;

    Abstract : With an increased demand on high-efficiency electrical machines in traction applications, better understanding in the losses induced by the converter is needed. The harmonic losses from the converter are non-negligible part of the total losses in an induction machine, and these harmonic losses have been studied here with a focus on iron, skin-effect and proximity losses.

  4. 3. Design and Analysis of a Fractional-Slot Concentrated-Wound Permanent-Magnet-Assisted Synchronous Reluctance Machine

    University essay from KTH/Elektrisk energiomvandling

    Author : Celia Carvajal Almendros; [2015]
    Keywords : Demagnetization; finite element method; flux-weakening; fractional slot concentrated winding; overload capability; permanent magnet assisted synchronous reluctance machine; torque ripple; Avmagnetisering; finita elementmetoden; fältförsvagning; koncentrerade lindningar; momentrippel; permanentmagnetassisterad synkron reluktansmaskin; överbelastningskapacitet;

    Abstract : The growing need for simpler and cheaper manufacturing process has led to the research into fractional-slot concentrated-wound (FSCW) motors. This concept has been widely investigated for surface-mounted permanent magnet (SMPM) machines. This thesis studies the same concept applied for synchronous reluctance machines (SynRM). READ MORE
