  1. 1. 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

  3. 2. Eddy Current Losses in the Vicinity of Reactor Air Gaps due to Fringing Flux

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Valdemar Stenlund; [2016]
    Keywords : ;

    Abstract : The objective of this report is to investigate the fringing flux around the air gap of a high frequency reactor and what correlation it has with losses, air gap length and frequency. A computer model is made using a finite element analysis software and a prototype reactor is built and tested on to verify the model. READ MORE

  5. 4. 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.

  6. 5. Electromagnetical model of an induction motor in COMSOL Multiphysics

    University essay from KTH/Elektrisk energiomvandling

    Author : Viktor Wilow; [2014]
    Keywords : Electromagnetical model; Induction motor; Finite element method; COMSOL Multiphysics;

    Abstract : Ansys, Flux or COMSOL are examples of software-tools that can be used to study magnetic noise, caused by magnetic forces in the air-gap, in induction motors. The project team wanted to use COMSOL in this thesis. The electromagnetical domain needs to be coupled to the mechanical domain to complete the study. READ MORE
