  1. 1. Design of a small-scale wave energy converter

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Sumaya Farjana; [2022]
    Keywords : small-scale point absorber; scaling factors; damping coefficient;

    Abstract : In this study, a small-scale point absorber wave energy converter has been designed contemplating a full-scaled point absorber in the Mediterranean Sea state. The scaling factor for the small-scaled version has been determined by the damping coefficient calculation of the power take-off in 1:10, 1:15, and 1:20 scaling factors. READ MORE

  3. 2. 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

  4. 3. Simulation, design and experimental validation of a passive magnetic damper for ultra-fast actuators

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Chen Chen; [2014]
    Keywords : Damping; Thomson actuator; eddy currents; magnets; ferromagnetic materials;

    Abstract : A contact system driven by a high energetic Thomson actuator requires to be decelerated from full speed down to zero. The forces originated from the interaction between a stationary copper tube and a moving array of magnets combined with plastic or ferromagnetic material are used to generate eddy-current damping.
