2. Evaluation of thermal expansion in busbars used for battery electric vehicles
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Thermal expansion can be an issue in solid busbars, the expansion is caused by several factors and can cause plastic deformation in connection points or structure around it. The expansion occurs due to temperature differences in the busbar as a result of altered ambient temperature and/or joule heating. LÄS MER
3. Study of Analytical Models for Harmonic Losses Calculations in Traction Induction Motors
Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)Sammanfattning : This Master Thesis deals with the study of analytical and finite-element (FE) models for calculation of losses in traction induction motors. Motors are fed through inverters for this type of application. Therefore, both fundamental and harmonic losses are considered. The study is done with one particular motor and one initial analytical model. LÄS MER
