    University essay from KTH/Produktionsutveckling

    Author : Simon Boström Leijon; [2023]
    Keywords : Finite element analysis; bending; stator winding; Finita element analys; böjning; statorlindning;

    Abstract : Electric propulsion in the heavy truck industry require knowledge in certain new areas involved in electric machine manufacturing. One of these new manufacturing steps is copper bending for production of stator windings. READ MORE

  3. 2. Machine Learning Models for Estimating Temperatures of Electric Powertrains

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

    Author : Dinan Li; [2022]
    Keywords : Powertrain; machine learning; temperature monitoring; neuron network; Drivlina; maskininlärning; temperaturövervakning; neuronnätverk;

    Abstract : Towards a sustainable future, more and more powertrains are being electrified today, thus it is important to prevent unwanted failures and secure a reliable operation. Monitoring the internal temperatures of powertrains and keeping them under their thresholds is an important first step. READ MORE

    Keywords : Quality assurance QA ; electrical testing; continuous hairpin winding; stator series production; Process-Failure Modes and Effects Analysis P-FMEA ; electric vehicles EVs ; Kvalitetssäkring QA ; Elektriska Test; Kontinuerlig Hårnålslindning; Stator Serie Produktion; P-FMEA; Elektriska Fordon EVs ;

    Abstract : The demands for sustainable transportation have made battery electric vehicles an increasingly popular subject in the world of both businesses and engineering. This thesis has been made in collaboration with Scania, which is currently investigating the possibility of manufacturing stators and rotors in-house in a series production line. READ MORE

  5. 4. 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

  6. 5. Real-time detection of stator resistance unbalances in three phase drives

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

    Author : Bhanu Pratap Singh; [2020]
    Keywords : DC voltage injection; Fault detection; Field-Oriented Control; Induction machine; Inter-Turn Short Circuit; Short circuit; Sequence; Stator resistance unbalance; Symmetrical components; likspänningsinjektion; feldetektering; fält orienterad reglering; induktionsmaskin; InterTurn Short Circuit; kortslut; sekvenser; statormotstånd obalans; symmetriska komponenter;

    Abstract : An estimated 30% of the faults in Induction Machine (IM) are related to its stator. These faults are mostly in the form of an Inter-Turn Short Circuit (ITSC) fault i.e., when two winding inside the stator of IM are shorted due to insulation failure. READ MORE
