  2. 1. 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. 2. Electric Traction Machine Design for an E-RWD Unit

    Author : Francisco Marquez; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Traction Machines; Permanent Magnet Machines; Laminated Winding Machines; Hybrid Electric Vehicles; Electrical Machine Design; Electromagnetic Modeling; Thermal Modeling; Finite Element Analysis.;

    Abstract : Since the first generation of the Toyota Prius was introduced in December 1997, the number of Hybrid Electric Vehicles (HEVs) and pure Electric Vehicles (EVs) available in the market has increased substantially. The growing competition existent puts high demands on the electric system as well as the rest of the vehicle. READ MORE

  5. 3. Integrated In-Wheel Motors for Low Power Traction Application

    Author : Prakashraj Kasinathan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric golf cart; integral-slot; force density; flux-linkage; traction motors; forklift trucks; direct-drive; electric wheelchairs power wheelchairs; low speed machines; fractional-slot;

    Abstract : This thesis is primarily concerned with the practical limits, imposed by magnetic saturation and thermal considerations, of the force density in low-speed permanent-magnet electric machines. The practical force density values obtainable in integral- and fractional-slot machines are determined. READ MORE

  7. 5. Towards Low-Voltage, High-Current : A pioneering drive concept for battery electric vehicles

    Author : Stefan Haller; Kent Bertilsson; Bengt Oelmann; Peng Cheng; Dieter Gerling; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low voltage; high current; EV; BEV; electrical machine; power electronics; MOSFET;

    Abstract : The first electric low-voltage vehicles were constructed in the mid-19th century, but by the early 20th century they were progressively replacedby successors with internal combustion engines. As the consequences ofusing fossil fuels are better understood, our society is now transitioning back. READ MORE
