  1. 16. Design of a Simulation Startup Model for a Marine Current Turbine

    Kandidat-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Isak Carlénius; Valle Johansson; [2020]
    Nyckelord :;

    Sammanfattning : This project is aimed at developing a simulation model in Simulink for a new startup system controlling the marine current turbine at Uppsala university's research facility in Söderfors. The goal is to design a circuit that is able to switch between feeding power to and extracting power from the synchronous machine in order to control the rotational speed of the turbine. LÄS MER

  3. 17. Fault detection of planetary gearboxes in BLDC-motors using vibration and acoustic noise analysis

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Henrik Ahnesjö; [2020]
    Nyckelord :Planetary gearbox; Fault detection; Condition Monitoring; Support Vector Machine SVM ; Machine Learning; Supervised Machine Learning; Defect Pinion; Defect Planet Gear; MATLAB; LabVIEW; Soundproof-box; Noise Vibration Harshness NVH ; Gearmesh Frequency GMF ; Power Spectrum; BLDC-motor;

    Sammanfattning : This thesis aims to use vibration and acoustic noise analysis to help a production line of a certain motor type to ensure good quality. Noise from the gearbox is sometimes present and the way it is detected is with a human listening to it. This type of error detection is subjective, and it is possible for human error to be present.

  4. 18. Door Simulator - Creating automated tests

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Annie Ydström; [2020]
    Nyckelord :Python; Simulator; PicoScope; Industrial door; Torque measurements; MATLAB; LabView; Instrument control; Technology and Engineering;

    Sammanfattning : This report describes the development of a simulator for the simulations if industrial doors. The project has been conducted at ASSA ABLOY Entrance Systems, industrial door solutions in Landskrona. The purpose of this thesis project was to design and implement a system that can replicate the behaviour of an industrial door on a test-rig. LÄS MER

  5. 19. Measurements of resistivity in transformer insulation liquids

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för elektroteknik

    Författare :Jonathan Hägerbrand; [2020]
    Nyckelord :transformer oil; resistivity; ions; ion drift model; HVDC; contact resistance;

    Sammanfattning : This thesis focuses on measuring techniques and results of resistivity in four commercially available insulating transformer oils: mineral oil, ester oil and two isoparaffin oils. Two measuring techniques, the industrially used diagnostic system for electrical insulation IDA and the Labview implemented Triangular Method, are used for resistivity measurements and the techniques are compared, a correction algorithm to the triangular method is suggested.

  7. 20. Färdigställande av datainsamlingssystem för elektronisk näsa

    Kandidat-uppsats, Högskolan i Gävle/Elektronik

    Författare :Jonathan Jakobsson; [2020]
    Nyckelord :elektronisk näsa; principalkomponentanalys; klassificering;

    Sammanfattning : Ett datainsamlingssystem för en elektronisk näsa utvecklat av tre studenter vid högskolan i Gävle har undersökts för att sedan vidareutvecklas. Det tidigare systemet utvecklades för att samla in data från en elektronisk näsa med fyra sensorkort. LÄS MER
