1. 21. Analysis of a light permanent magnet in-wheel motor for an electric vehicle with autonomous corner modules

   Uppsats för yrkesexamina på avancerad nivå, KTH/Elektrisk energiomvandling

   Författare :Sergio Romero; [2011]
   Nyckelord :;

   Sammanfattning : The use of in-wheel motors is an attractive alternative in small passenger vehicles aimed for transportation in urban areas. The improved control possibilities and the removal of certain components such as the transmission systemare some of its advantages. LÄS MER

3. 22. Finite-Element Based Shape-Optimization of Electric Motors

   Master-uppsats, Lunds universitet/Industriell elektroteknik och automation

   Författare :Tobias Månsson; [2010]
   Nyckelord :Technology and Engineering;

   Sammanfattning : By introducing spectral or polynomial functions to perturb the shape of the rotor in an electrical machine that was previously optimized by conventional means, it was shown that performance parameters can be further improved, in some cases significantly. This was accomplished by developing and applying an optimization method designed for use with a commercial finite element simulation software (Maxwell). LÄS MER
