To meet the increasingly stringent regulations on operational efficiencies of electric motors, efforts have been devoted to design and construct motors with less power losses. Without the need of rotor conductors and hence no secondary copper loss, the feasibilities of applying synchronous reluctance motor (SynRM) have attracted many attentions on the related industries. Since the operation of SynRM...
This paper is aimed to present the systematic design scheme of a direct driven slotless tubular linear generator for renewable energy retraction. To reduce operational cogging and increase energy conversion efficiency, the generator stator is equipped with slotless concentrated annular multiphase windings and its mover is encircled by quasi-Halbach arranged permanent magnets. By systematic comparisons...
Nowadays, ontology of subject knowledge is applied for intelligent e-learning to provide learners with adaptive learning guidance and efficient learning content management. However, it is difficult and costly to construct an ontology for a given domain even though using the GUI tools. Therefore, how to propose an easy way to acquire the knowledge of experts, how to integrate these diverse opinions...
