  1. 1. Pulse-width voltage modulation in the Python-based open-source simulator Motulator : A Realization of SVPWM, Harmonic analyzer and Over-modulation on Two and Three-level Inverters, and a Solution for Unbalanced Neutral Point Voltage on Three-level Inverters

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jiale Deng; [2023]
    Keywords : Three-level inverters; over-modulation techniques; space vector modulation; neutral-point voltage balancing; non-uniform Fourier transform; Trenivåväxelriktare; övermodulation; spacevektormodulering; balansering av nollpunktsspänning; olikformig Fouriertransform;

    Abstract : Controlling the dynamic outputs of electrical machines has always been an essential topic in aerospace, automotive and other industries. Electrical machine control consists of several components, each of which can be controlled in various ways. Whereas the dynamic responses are mostly simulated using MATLAB/SIMULINK, Prof. READ MORE

  3. 2. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Muhammad Umar Farooq; [2023]
    Keywords : Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

    Abstract : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces.

  4. 3. Competitor analysis of the synchronous machines market : A study of how manufacturers differentiate themselves from each other with unique value propositions

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Fredrick Fager; Jiyan Kösanlioglu; [2023]
    Keywords : Synchronous machines; synchronous motors; synchronous generators; competitor analysis; value proposition; Synkronmaskiner; synkrona motorer; synkrona generatorer; konkurrentanalys; värdeerbjudande;

    Abstract : This report highlights the market for synchronous machines and examines the current situation. Today, the world demands higher volumes of electrical power that is cleaner, more efficient and generated from fossil-free sources. This increases the importance of using efficient and modern that minimise energy losses. READ MORE

  5. 4. Rotor temperature estimation in Induction Motors with Supervised Machine Learning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Christopher Gauffin; [2023]
    Keywords : Induction motors; Supervised Machine learning; Power converters; Parameter estimation; Embedded systems; Induktionsmotorer; Övervakad maskininlärning; Strömkonverterare; Parameterestimering; Inbyggda system;

    Abstract : The electrification of the automotive industry and artificial intelligence are both growing rapidly and can be greatly beneficial for a more sustainable future when combined. Induction machines exhibit many complex relationships between physical and electromagnetic properties that must be calculated in order to produce the correct quantities of torque and speed commanded by the driver.

  6. 5. Evaluation of electric actuation for fighter aircraft

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Dennis Moliner Pettersson; Anton Nygårds; [2023]
    Keywords : EMA; actuator; actuation; MEA; aircraft; PMSM; SHA;

    Abstract : The tendency of recent years towards electrification of aircraft components and subsys-tems has opened the door for a wider usability of electro-mechanical actuators (EMAs) inthat context. EMAs are already in use in aircraft industries but mainly in civil aviation forsecondary control systems and non-critical applications. READ MORE
