  3. 2. Fatigue analysis of laser welded hairpins in electric car motors

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Francisco Martín Ruiz; Imanol Iribar Rodriguez; [2022]
    Nyckelord :;

    Sammanfattning : Hairpins are copper filaments used in the windings in the stators of electric motors in modern times. For the motor to work, they have to be welded in pairs, normally with laser welding. Studying the fatigue response of the joint of hairpins welded with a set of values of laser welding process parameters is the main objective of this project. LÄS MER

  4. 3. Laserparametrars påverkan på svetsdjup och porbildning för lasersvetsade koppar-hairpins

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Jessica Pettersson; [2021]
    Nyckelord :;

    Sammanfattning : Detta examensarbete handlar om lasersvetsning av koppar-hairpins som används som statorlindning i elmotorer. Vid lasersvetsning kan olika parametrar väljas som lasereffekt, matningshastighet med mera. LÄS MER
