  1. 21. Lifetime prediction of sealing component using machine learning algorithms

    University essay from Lunds universitet/Produktionsekonomi

    Author : Olof Jansson; [2016]
    Keywords : Analytics; Machine Learning; Microsoft Azure; Condition Monitoring; Predictive Maintenance; Technology and Engineering;

    Abstract : Tetra Pak is a world leader in the food packaging industry and has been so for a very long time. In recent years however, they are experiencing increased competition from low-cost suppliers selling their previously patented paper as a commodity. This has forced Tetra Pak to focus more on selling complete systems and services. READ MORE

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

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Ata-E Rabbi; [2016]
    Keywords : Synchronous machine; interturn fault; stator fault; rotor current; harmonic current; generator protection; motor protection; inductance matrix.; synkronmaskin; varvfel; statorström; rotorström; strömöverton;

    Abstract : 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. READ MORE

  4. 23. Damper Winding Fault Detection in Synchronous Machines

    University essay from

    Author : Fredrik Holmgren; [2016]
    Keywords : Fault detection; condition monitoring; motor diagnostics; synchronous machines; synchronous motors; electrical machines; motor drives; damper winding; damper bars;

    Abstract : This thesis aims to identify methods for detection of damper winding faults in synchronous machines (SMs) powered by variable frequency drives (VFDs). The problem of failing damper windings has received attention after reports of serious damage which have been discovered during maintenance checks. READ MORE

  5. 24. PMSM diagnostics and prognostics - Evaluation of an on-line method based on high frequency current response

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Julius Björngreen; [2016]
    Keywords : Technology and Engineering;

    Abstract : This thesis covers and evaluates a stator insulation fault detection method for Permanent Magnetised Synchronous Machines (PMSMs). The method could be implemented on-line and is based on using the power converter in an electric or hybrid vehicle to measure the State of Health (SoH) of the stator insulation of the PMSM.
