  1. 1. Thermal Modelling of Small Cage Induction Motors

    Author : Gunnar Kylander; Chalmers University of Technology; []
    Keywords : thermal network; thermal model; losses; TEFC; induction motor;

    Abstract : The loadability of electric machines is above all determined by temperature limits. In this work, thermal network models, suitable for totally enclosed fan cooled (TEFC) induction motors, are used to predict the machine temperatures. READ MORE

  2. 2. Development of competence in biochemical experimental work : Assessment of complex learning at university level

    Author : Christina Bergendahl; Lena Tibell; Lisbeth Lundahl; Lars-Owe Dahlgren; Umeå universitet; []

    Abstract : Biochemistry is part of life science: a fast developing multidisciplinary area. The overall aims of this thesis and the work underlying it were to find ways in which to develop competence in biochemistry at university level and to assess complex learning. A particular interest was the development of experimental work as a means to promote learning. READ MORE

  4. 4. Internal Design of a Class of Self-Excited Synchronous Generators

    Author : Mohamed Wadi; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soft Magnetic Composites; Hydropower Plants; Brushless Excitation; Self-Excited Generators; Renewable Energy; Reluctance Generators; Synchronous Generators; Small Hydropower;

    Abstract : INTERNAL DESIGN OF A CLASS OF SELF-EXCITEDABSTRACTWith the increasing trend of distributed generation and the need for alternative and renewable energy sources, self-excited induction and synchronous reluctance generators have attracted more attention for wind, tidal and hydropower applications. This thesis is concerned with the development of a class of self-excited synchronous reluctance generators (SRG). READ MORE

    Abstract : The focus on our environment has never been as great as it is today. The impact of global warming and emissions from combustion processes become increasingly more evident with growing concerns among the world’s inhabitants. The consequences of extreme weather events, rising sea levels, urban air quality, etc. READ MORE
