4. 3. 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

5. 4. Simulation of distributed windings using the insert technique

   Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

   Författare :Hue Hoang; Matilda Widerström; [2019]
   Nyckelord :Abaqus CAE; Simulation; Insert technique; Electric motor; Stator; Explicit finite element method; Windings; FEM; Abaqus CAE; Simulation; Insert technique; Elektrisk motor; Stator; Explicit finit elementmetod; Lindningar; FEM;

   Sammanfattning : During the insert process when the windings of an electric motor are pushed into the stator slots, some detrimental phenomena can occur that affect the efficiency and life of the motor. To detect these phenomena and optimize the process, a simulation would be useful. LÄS MER
