  1. 1. Thermal Modelling of Permanent Magnet Synchronous Motor Windings in Heavy-Duty Electric Vehicles

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Ken Dahl; [2023]
    Nyckelord :PMSM; permanent magnet synchronous motor; synchronous motor; black-box modelling; black-box models; thermal modelling; lumped parameter thermal network; LPTN; electric machine; EM; EV; electric vehicle; winding;

    Sammanfattning : A significant challenge with permanent magnet synchronous motors (PMSMs) is thermal management. Thermal stress can lead to irreversible damage to components, and to enable efficient cooling, a thermal model is needed. LÄS MER

  3. 2. Analysis of Cooling System and Its Influence on Magnetic Flux Density in a Motor

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Ronaldo Gustav Pangihutan Hasibuan; [2020]
    Nyckelord :Generator; Motor; Permanent Machine;

    Sammanfattning : After Michael Faraday invented the magnetism theory in 1821, the application of the permanent magnet machine was rapidly developed. The permanent magnet synchronous machine is one of the popular applications of electromagnetic theory, which is implemented in most electric vehicles nowadays. LÄS MER

  4. 3. Directly Cooled Windings - Conjugate heat transfer assessment of air-cooled hollow conductor

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Michael Gabassi; [2018]
    Nyckelord :Conjugate heat transfer; hollow conductor; thermal management; direct cooled windings; heat transfer; electrical machines; Technology and Engineering;

    Sammanfattning : The torque capabilities of electrical machines are today limited by magnetic saturation and the ability to transfer thermal loads away from the machine. A solution to thermal management in power turbo-generators involves hollow conductors allowing direct cooling of the heat source thus increasing the power density significantly. LÄS MER

  5. 4. Improved Thermal Models for Predicting End Winding Heat Transfer

    Master-uppsats, KTH/Elkraftteknik

    Författare :Gabriele Luca Basso; [2017]
    Nyckelord :;

    Sammanfattning : The thermal analysis is of primary importance for the design of any kind of electrical machine. The cooling has a significant impact on the electromagnetic performances and on the durability and reliability of the machine. LÄS MER

  7. 5. Environmental stress of electrical machine winding insulation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Martin Risemark Eriksson; [2017]
    Nyckelord :;

    Sammanfattning : The conducting winding of an electrical machine is insulated in order to prevent any short circuits to occur within the machine. This insulation is during its lifetime exposed to several environmental stresses and therefore plays an important role in the life length of the machine. LÄS MER
