1. Feasibility Study on Additive Manufacturing of Copper Windings using Electron Beam Melting
Master-uppsats, KTH/ProduktionsutvecklingSammanfattning : Within the framework of this thesis, the electron beam melting of pure copper for the purpose of producing electrical windings was examined. The conventional manufacturing process of copper windings was investigated, and the potential advantages offered by the design freedom inherent in the electron beam melting process were explored.

2. Fatigue analysis of laser welded hairpins in electric car motors
Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskapSammanfattning : 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
3. Laserparametrars påverkan på svetsdjup och porbildning för lasersvetsade koppar-hairpins
Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskapSammanfattning : 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
4. Quality Assuring of Stator Winding Production : Using electrical tests to quality assure the process steps of a series stator winding production
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The demands for sustainable transportation have made battery electric vehicles an increasingly popular subject in the world of both businesses and engineering. This thesis has been made in collaboration with Scania, which is currently investigating the possibility of manufacturing stators and rotors in-house in a series production line. LÄS MER
