  1. 6. Finite-element analysis of an induction motor with inter-turn short-circuit faults

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

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

    Abstract : 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. READ MORE

  3. 7. 3D Finite Element Analysis of a Hybrid Stepper Motor

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

    Author : Yuanji Fan; [2019]
    Keywords : ;

    Abstract : Hybrid stepper motors are being applied to more and more industrial regionsdue to their low cost compared with servo motors and prominent performance.Many industrial applications require accurate and eective methods for predictinga motor’s performance at the design stage. READ MORE

  4. 8. Stiffness Re-Design and Insert Solutions for the ZBee

    University essay from KTH/Lättkonstruktioner

    Author : Ehimenmen Michael Inegbedion; [2018]
    Keywords : ;

    Abstract : This thesis presents a systematic approach to solving the problem of large deflections in the ZBee vehicle, proposing feasible insert solutions while reducing weight and increasing efficiency were possible.An experimental study was done on the structural deformations of a sample ZBee floor using highly advanced measuring instruments.

  5. 9. Buckling of End-Bearing Retaining Walls in Clay

    University essay from KTH/Jord- och bergmekanik

    Author : Fredrik Jansson; Nils Nilsson; [2018]
    Keywords : Berliner walls; Critical loads; buckling; finite element model; Eurocode 3; Berlinerspont; Rörspont; kritisk knäckningslast; knäckning; finit element modell; Eurocode 3;

    Abstract : The design of back-anchored retaining walls in Sweden has traditionally not included global elastic instability of the retaining wall as a possible failure mode. Eurocode 3 part 5 (SS-EN 1993-5) requires design of steel structural members for retaining walls to assess the risk of buckling if the normal force exceeds 4 % of the critical buckling load of the retaining wall.

  6. 10. Transonic Flutter for aGeneric Fighter Configuration

    University essay from KTH/Flygdynamik

    Author : Axel Bååthe; [2018]
    Keywords : Flutter; Aeroelasticity; Transonic; Unsteady Aerodynamics; Doublet-Lattice Method; Full-Potential Equation; PK-Method;

    Abstract : A hazardous and not fully understood aeroelastic phenomenon is the transonic dip,the decrease in flutter dynamic pressure that occurs for most aircraft configurationsin transonic flows. The difficulty of predicting this phenomenon forces aircraft manufacturersto run long and costly flight test campaigns to demonstrate flutter-free behaviourof their aircraft at transonic Mach numbers.
