  1. 16. Modeling of Energy-Efficient Robots for Lightweight, High Volume Assembly : Concepts and Optimization

    Författare :Sten Grahn; Björn Langbeck; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Commercial and environmental demands put constant pressure on robot manufacturers to improve the efficiency of the robots they produce. Satisfying answers to efficiency questions can have a major impact on both manufacturers and users. LÄS MER

  3. 17. Diagnosability analysis and FDI system design for uncertain systems

    Författare :Daniel Eriksson; Erik Frisk; Mattias Krysander; Alexander Medvedev; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Our society depends on advanced and complex technical systems and machines, for example, cars for transportation, industrial robots in production lines, satellites for communication, and power plants for energy production. Consequences of a fault in such a system can be severe and result in human casualties, environmentally harmful emissions, high repair costs, or economical losses caused by unexpected stops in production lines.

  5. 19. Electromagnetic Energy Converters - Rotating Motors and Linear Generators

    Författare :Boel Ekergård; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : This licentiate thesis presents a study of the electromagnetic properties of linear synchronous permanent magnet generators, utilized in wave energy converters, and a two pole permanent magnet motor for an electrical vehicle. Both machine topologies are presented, designed with a numerical simulation tool, based on a model derived from Maxwell’s equations. LÄS MER

  7. 20. Kinetic Energy Storage and Magnetic Bearings, for vehicular applications

    Författare :Johan Abrahamsson; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : One of the main challenges in order to make electric cars competitive with gaspowered cars is in the improvement of the electric power system. Although many of the energy sources currently used in electric vehicles have sufficiently high specific energy, their applicability is limited due to low specific power. LÄS MER
