  1. 11. Design and Simulation of a Slotless Aircored PM Synchronous Generator

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Bakhtiyar Asef Hasnain; Ademir Hodzic; [2020]
    Keywords : Slotless; Aircored; PM; Permanent Magnet; PMSG; Permanent Magnet Synchronous Generator; SPMSG; COMSOL; FEMM; FEM; Solidworks; Fusion 360; Axial Flux Generator;

    Abstract : This thesis is a study on an unconventional slow speed direct drive permanent magnet (PM) generator. Unlike a standard permanent magnet synchronous generator (PMSG) which has the copper coils wound around iron teeth, the work in this thesis will present a generator where the copper coils are directly mounted on the stator which eliminates the slots and teeth in the generator.

  3. 12. The Price, Quantity, and Welfare Impacts on the EU Following Increased Import Tariffs: An empirical estimation of 2018’s trade retaliation against the U.S.

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Sofie Andersson; [2019]
    Keywords : EU; U.S.; tariffs; trade; welfare losses; Business and Economics;

    Abstract : This paper explores the impacts of EU’s retaliatory tariffs towards the U.S. on prices, quantities, and welfare. Over the course of 2018, the Trump Administration imposed tariffs on EU steel and iron, to which the EU implemented counter measures of increased tariffs on U. READ MORE

  4. 13. Reduction of a Detailed Thermal Model Lumped Parameters Approach for an OSV Induction Motor

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

    Author : Luca Roggio; [2019]
    Keywords : ;

    Abstract : This thesis work is dealing with a detailed thermal model for an open self ventilated inductionmachine with lumped parameters approach. The model is entirely built using as referencespublished articles. The thermal network is tested using both MATLAB for calculating theparameters and SimScape for simulations and validation.

  6. 15. Experimental Study of Metallic Surfaces Exposed to Cavitation

    University essay from KTH/Materialvetenskap

    Author : Marcio Freitas De Abreu; [2018]
    Keywords : cavitation; cylinder liner; lamellar gray cast iron; erosion pitting; graphite class; cavitation;

    Abstract : Cylinder liners in heavy-duty truck engines are subjected to intense vibrations and may sustain damage from the cavitation of bubbles in the coolant liquid, with some risks of leakage and engine breakdown. An ultrasonic oscillating probe was used to simulate the pitting rates and behavior of samples extracted from cylinder liners, which are made of grey cast iron, with differences in surface roughness, glycol and inhibitor content in coolant, coolant temperature and graphite flake class; bainitic microstructures were also tested.
