  2. 21. 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

  4. 22. A Helping Hand : On Innovations for Rehabilitation and Assistive Technology

    Author : Mats Nilsson; Hans von Holst; Metin Akay; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hand function; Mechatronic system; Orthose; Neurological rehabilitation; Brain-Computer Interface; Functional Electric Stimulation;

    Abstract : This thesis focuses on assistive and rehabilitation technology for restoring the function of the hand. It presents three different approaches to assistive technology: one in the form of an orthosis, one in the form of a brain-computer interface combined with functional electrical stimulation and finally one totally aiming at rehabilitating the nervous system by restoring brain function using the concept of neuroplasticity.

  6. 24. The Pneumatic Hybrid Vehicle - A New Concept for Fuel Consumption Reduction

    Author : Sasa Trajkovic; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VVA; Regenerative; Air-motor; Compressor; Pneumatic; Hybrid; Vehicle; Electric Hybrid; Drive Cycle; GT-Power; Simulink; FPGA;

    Abstract : Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional internal combustion engines (ICE) could be saved, the fuel economy would improve. READ MORE

  7. 25. Energy Efficiency of an Electric Vehicle Propulsion Inverter Using Various Semiconductor Technologies

    Author : Ali Rabiei; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drive cycles; Vehicle applications; Dc-link; Electric machines; Loss calculation; Power electronics; Silicon carbide; Current vector control; Nonlinear Optimization; Energy efficiency;

    Abstract : In this Licentiate thesis, various solutions to improve the efficiency in the electrical vehicledrive drive line such as in the propulsion inverter and in the electric machine, are proposedand their benefits are quantified from an energy efficiency point of view. The efficiencyanalysis is based on modeling of a power electronics inverter, an electric machine and abattery in various drive cycles of an electric vehicle. READ MORE
