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

   University essay from Linköpings universitet/Fordonssystem

   Author : Ken Dahl; [2023]
   Keywords : 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;

   Abstract : 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. READ MORE

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

   University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

   Author : Francisco Martín Ruiz; Imanol Iribar Rodriguez; [2022]
   Keywords : ;

   Abstract : 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. READ MORE

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

   University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

   Author : Hue Hoang; Matilda Widerström; [2019]
   Keywords : 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;

   Abstract : 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. READ MORE
