  1. 1. Creative development of lightweight façade constructions in modular housing : The struggle to shut out the noise of the world

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Johan Albihn; [2022]
    Keywords : Acoustical engineering; façade wall construction; modular housing; traffic noise reduction; lightweight construction; industrial design engineering; Akustik; fasadväggkonstruktion; modulhus; reducering av trafikbuller; lättviktskonstruktion; teknisk design;

    Abstract : Modular construction of housing is an industry on the rise. The prefabrication of construction modules gives a greater control over material consumption, promotes standardization, and lessens the disturbance during the construction time in the field. Lindbäcks Bygg AB prefabricates housing modules in their factory at Haraholmen, Piteå. READ MORE

  3. 2. Cooling simulation of a BEV electrical machine rotor

    University essay from KTH/Fordonsdynamik

    Author : Lisa Sparv; [2021]
    Keywords : Electrical machine; Rotor cooling; Permanent magnet; Simulation; STAR-CCM ; Elmaskin; Rotorkylning; Permanentmagnet; Simulering; STAR-CCM ;

    Abstract : The thesis work described in this report is about simulation of the cooling of an electrical machine rotor. Limitations and simplifications were made on the CAD model of the rotor with the purpose of reducing the simulation time, for it to then be used for CFD-simulations using STAR-CCM+. READ MORE

  4. 3. Analytical Approach to Understanding the Tooth Height Variations of the Stator in an Axial Flux Machine and its Impact on the Airgap

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Louise Lövgren; [2019]
    Keywords : Stator; axial flux machine; Höganäs; Soft Magnetic Composites; SMC; Somaloy; flatness; tooth height; airgap; crimping; Technology and Engineering;

    Abstract : Höganäs AB is developing an axial flux machine, where an even airgap between the stator and rotor is a vital parameter when designing a well functioning machine. It is believed that the stator is the component that introduces the biggest variations to the airgap, and that is why the stator is the object of investigation for this thesis. READ MORE
