  1. 1. Dielectric Response and Partial Discharge Characteristics of Stator Winding Insulation System with SiC Stress Grading

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

    Author : Amar Abideen; [2020]
    Keywords : Stator Insulation; Dielectric Frequency Response; Polarization Depolarization Current; Insulation Modelling; FEM simulation;

    Abstract : The typical construction of a stator coil includes the use of end corona protection (ECP)coating, which is made of semi-conductive materials like silicon carbide (SiC). Thepurpose of ECP is to smooth the electric stress distribution near the slot exit, limitingthe electric field and partial discharge (PD) activity within the insulation system. READ MORE

    Abstract : Windows has been always considered as heat sinks and they can account more than 25% of a building envelope. For this reason, its design and performance in dwellings play a major role in regulating the indoor environment. READ MORE

  4. 3. Thermo-mechanical Fatigue of Electrical Insulation System in Electrical machine

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Ahmed Elschich; [2017]
    Keywords : Thermal mechanical fatigue; Thermo-mechanical stress; electrical machine windings; electrical insulation system; slot insulation; slot liner; groundwall insulation; conductor insulation; turn insulation; stator;

    Abstract : Electrical machines in electrified heavy-duty vehicles are subjected to dynamic temperature loadings during normal operation due to the different driving conditions. The Electrical Insulation System (EIS) in a stator winding is aged as an effect of these dynamic thermal loads. READ MORE

  5. 4. Skin and proximity effect analysis of traction motor

    University essay from KTH/Elektrisk energiomvandling

    Author : Ricardo Huaytia Fernandez; [2012]
    Keywords : ;

    Abstract : Traction motors are thermally pressed to obtain a high torque per unit volume at the same time as a relatively high frequency is used. Because of the high frequency the phenomenon skin effect and proximity effects appear, this is explored in the thesis. To find a link between the parasitic and thermal effects on the insulation is important. READ MORE
