  1. 11. Thermomechanical stress analysis of the main insulation system of traction electrical machines

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Dahman Ismail; Alexis Andrei; [2020]
    Keywords : finite element analysis; thermo-mechanical stress; heavy-duty vehicle; electrical machine; insulation system; coupled-temperature displacement analysis; finita element analys; termomekaniska spänningar; lastbilar; elektriska motorer; isolering; termisk kopplingsförbindelse;

    Abstract : More efficiency heavy-duty vehicles are developed with higher range, updated electronic and mechanical parts. The fuel efficiency and pollution of carbon dioxide need to be lower to achieve new EU regulations. The global population increases with an increased number of heavy-duty vehicles. This, in turn, increases the emission. READ MORE

  3. 12. Stabilization of Constant Power Loads Using Model Predictive Control

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

    Author : Mikael Glamheden; [2020]
    Keywords : ;

    Abstract : This thesis considers stabilization of constant power loads (CPLs) fed by a dcpower source through an input filter, using model predictive control (MPC).Train propulsion systems generally utilize electrical motors whose output torqueis tightly regulated by power converters. Often, these systems behave as CPLs. READ MORE

  4. 13. Real-time stator resistance estimation for electrical drives : a control perspective

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

    Author : Fredric Sunesson; [2020]
    Keywords : ;

    Abstract : The automotive industry is in the middle of a rapid transition towards electrical machines. This transition leads to a higher interest in electrical machine management. In this thesis a stator resistance estimation scheme for field oriented controlled motors is proposed and tested in both simulations and experiments. READ MORE

  5. 14. Investigation of the potential of e-axles for trucks

    University essay from KTH/Fordonsdynamik

    Author : Marina Fernandez Carnota; [2020]
    Keywords : truck; e-axles; concepts; lastbil; e-axlar; koncept;

    Abstract : As a step to reduce emissions of trucks, Scania investigates different solutions related to electrification to contribute with more environmental friendly vehicles. The aim of this project is to investigate the potential of electrified axles, e-axles, to use in Scania trucks. READ MORE

  6. 15. Calibration and Estimation of Dog Teeth Positions in Synchronizers for Minimizing Noise and Wear during Gear Shifting

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

    Author : Qianyin Kong; [2020]
    Keywords : Synchronizer engagement; gear shifting; dog teeth; particle swarm optimization; Synkroniserare; Växling; Dog-teeth; Partikelsvärmoptimering;

    Abstract : Electric motors are used more widely in automotive to reducing emissions in vehicles. Due to the decreased usage of internal combustion engines which used to be the main noise source, impacts from synchronizers cannot be ignored during gear shifting, not only causing noise and wear but also delaying gear shifting completion.
