  1. 1. Magnetic field separation for current prediction in three-phase systems : Regression-based current prediction

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Sara Lenman; Sofia Blaad; [2023]
    Nyckelord :Alternating Current; Crosstalk Separation; Magnetic field sensors; Regression; Sensor technology; Three-phase system;

    Sammanfattning : Current controls the motion of a manipulator. The manipulators at ABB are powered by a three-phase alternating current system where shunt resistors are utilised to measure the current to the motors. Magnetic field sensors are instead investigated to eliminate issues with power losses, the number of components and the cost of the shunt resistors. LÄS MER

  3. 2. Enhancing Servo System Performance : Robust Nonlinear Deadbeat Predictive Current Control for Permanent Magnet Synchronous Motors

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

    Författare :Xingyu Zhao; [2023]
    Nyckelord :keywords here: Deadbeat Predictive Current Control; Permanent Magnet Synchronous Motor; Flux Linkage Nonlinearity; Parameter Inaccuracies; Nonlinear Feedforward Compensation; Delayed Integral Action.; Deadbeat-prediktiv strömreglerin; Permanenta magnet-synkronmotorn; Ickelinjäriteter i flödeslänkningen; Felaktigheter i parametrar; Icke-linjär framåtmatningskompensation; Fördröjd integralåtgärd.;

    Sammanfattning : The Permanent Magnet Synchronous Motor (PMSM, also known as the servo motor) is a crucial component within robotic servo systems. To optimally respond to the torque demands sent from the high-level motion controller, the PMSM current controller must track the reference with speed and precision. LÄS MER

  4. 3. Causes of and solutions to reduce excess material in production processes : A study of electrical motors and generators at ABB Machines

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Wilma Fager; Hanna Engberg; [2023]
    Nyckelord :Excess material; investigation; production processes; reduce; material usage; minimize; components;

    Sammanfattning : This thesis focus on the investigation of material usage in the production processes of electrical motors and generators at ABB Machines, a company based in Västerås, Sweden. The study aims to understand the reasons for the occurrence of excess material after the assembly of a motor or generator and explore possible solutions to minimize its occurrence. LÄS MER

  5. 4. Industriell symbios : En utredning om tillvaratagande av industriell spillvärme från en kylprocess

    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Oskar Magnusson; Jonathan Böckert; [2022]
