  1. 1. FEM Simulation Study of Iron Losses for a Linear Generator

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Pramod Hassan Kantharaj; [2021]
    Nyckelord :;

    Sammanfattning : Over the past few years, electricity generation from renewable resources has increased. Power generation from the ocean waves is also one among them. The technology consists of many subsystems. Generators are considered the heart of the entire subsystem or technology. LÄS MER

  3. 2. Communication Channel Measurement and Modeling for Inductive Wireless Power Transfer

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

  4. 3. Implementation and experimental evaluation of a parameterized PMSynRM model using Matlab and Comsol Multiphysics

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Israt Jahan; [2019]
    Nyckelord :Comsol Multiphysics; eddy-current losses; permanent-magnet synchronous reluctance motors; reluctance; Comsol Multiphysics; virvelströmsförluster; permanentmagnet synkrona reluktansmotorer; reluktans;

    Sammanfattning : 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. LÄS MER

  5. 4. Eddy Current Losses in the Vicinity of Reactor Air Gaps due to Fringing Flux

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

    Författare :Valdemar Stenlund; [2016]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  7. 5. MV BLDC motor fed with cascaded cell commutated converter

    Master-uppsats, KTH/Elektrisk energiomvandling

    Författare :MD. Rayhan; [2011]
    Nyckelord :;

    Sammanfattning : The purpose of this report is to study a medium voltage brushless DC (BLDC) motor for the Cascaded Cell Commutated (CCC) drive topology for high power applications. Presently AC motors and drives are dominant industrial solutions in both low and medium voltage drives. They have advanced machine design and control technology. LÄS MER
