  1. 1. Analysis and control of magnetic forces in synchronous machines

    Författare :J. J. Pérez-Loya; Urban Lundin; Anouar Belahcen; Uppsala universitet; []
    Nyckelord :eccentricity; electromagnetics; electromagnetic forces; excitation; magnetic fields; magnetic forces; magnetic thrust bearing; rotor drive; split rotor; starting; synchronous generators; synchronous machines; synchronous motors; unbalanced magnetic pull; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : In a synchronous machine, radial, tangential, and axial forces are generated. In this thesis, three different technologies to control them are proposed. The first one, involves the utilization of the radial forces that arise between the rotor and the stator. LÄS MER

  5. 4. Participating in Synchronous Online Education

    Författare :Stefan Hrastinski; Institutionen för informatik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Technological sciences; Samhällsvetenskaper; Social sciences; systemteori; Computer-mediated communication; Online participation; Synchronous communication; Online education; Teknik; E-learning; Distance education; Informatics; Informatik; systems theory;

    Sammanfattning : There is an increasing need for education since the workforce of today is expected to be highly educated and continuously learn. Distance education is a powerful response to meet the growing need for education. Online education, here concisely defined as distance education mediated online, is the most common type of distance education. LÄS MER

  7. 5. Synchronous Belt Mechanics and Durability - An Investigation Towards Life Prediction

    Författare :Tomas Johannesson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; load distribution model; synchronous; camshaft drives; mathematical modelling; timing; belt; dynamic; wear; simulation; automotive; belt life prediction;

    Sammanfattning : An automotive synchronous belt transmits power and assures accurate timing between the crankshaft and camshafts. The automotive industry is very competitive: there is constant pressure to increase performance and lower costs. LÄS MER
