2. 1. Integrated Compact Drives for Electric and Hybrid Electric Vehicles

   Author : Lebing Jin; Hans-Peter Nee; Staffan Norrga; Oskar Wallmark; Robert Pilawa-Podgurski; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distributed control; electric vehicle; energy storage capability; integrated motor drive; modular converter; modulation; power losses; stacked polyphase bridges converter; switching frequency; Electrical Engineering; Elektro- och systemteknik;

   Abstract : To develop more competitive solutions, one of the trends in the development of drive systems for electric and hybrid electric vehicles (EVs/HEVs) is to integrate the power electronic converter and the electric motor. This thesis aims to investigate the performance and the operation of modular converters in integrated motor drive systems for EVs/HEVs. READ MORE

7. 5. An Interactive Traction Motors Design and Selection Software

   Author : Hasan El Hinaoui-Hamze; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CAD; Access; Electric Drives; Visual Basic; Internal Combustion Engines ICEs ; · Electric Motors EMs ; SQL; MATLAB; Hybrid Electric Vehicles HEVs ; Traction Motors; MagNet;

   Abstract : Use of electric motors in vehicle traction, in fact, predates the internal combustion engines (ICEs). Electric vehicles powered by dc motors were known as far back as 1890. Compared with vehicles powered by ICEs, the main drawback of the early electric vehicles was, and still is, their limited range and long recharging time. READ MORE
