  1. 1. Fault Detection in Permanent Magnet Synchronous Motors using Machine Learning

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Alexander Lennartsson; Martina Blomberg; [2021]
    Nyckelord :PMSM; Fault Detection; AI; artificial intelligence; Machine Learning; inter turn short circuit; inter turn short fault; turn-to-turn; permanent magnet synchronous motor; short circuit; fault; avionics; airplane; aircraft;

    Sammanfattning : In the aviation industry, safety and robustness are the number one priorities, which is why they use well-tested systems such as hydraulic actuators. However, drawbacks such as high weight and maintenance have pushed the industry toward newer, electrical, actuators that are more efficient and lighter. LÄS MER

    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Finite-element analysis of an induction motor with inter-turn short-circuit faults

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

    Författare :Hareesh Babu; [2020]
    Nyckelord :Finite element analysis; stator winding fault; inter-turn short circuit.; Finit-element analys; statorlindningsfel; kortslutning mellan varv.;

    Sammanfattning : Stator inter-turn short circuit (ITSC) faults are one of the common sources for induction machine failure affecting their reliable operation. In this thesis, a finite element (FE) model is developed to study the ITSC fault. The FE model is developed for a prototype induction machine that has the potential to emulate an ITSC fault in the stator. LÄS MER

  5. 4. Detection of stator interturn fault of synchronous machine by rotor current analysis : A SIMULATION APPROACH

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Nyckelord :Synchronous machine; interturn fault; stator fault; rotor current; harmonic current; generator protection; motor protection; inductance matrix.; synkronmaskin; varvfel; statorström; rotorström; strömöverton;

    Sammanfattning : One of the major electrical faults of synchronous machines is an interturn short circuit in the stator winding, due to winding insulation failure. A synchronous machine is designed to have electrical and mechanical symmetry in the stator and rotor. LÄS MER

  7. 5. Analysis of fault conditions in permanentmagnet in-wheel motors

    Master-uppsats, KTH/Elektrisk energiomvandling

    Författare :Yonghui Liao; [2011]
    Nyckelord :;

    Sammanfattning : The use of light in-wheel motors is an attractive alternative for smaller passenger vehicles in urban areas. An in-wheel motor design has already been developed in a previous master thesis project. In this project, the proposed design is further analysed during electrical faults using a FEM software package (JMAG). LÄS MER
