Lineer indüksiyon motorların teorik incelenmesi ve uygulama örnekleri

Abstract

ABSTRACT Linear Induction Motors rarely achieve the performance, in terms of power factor or efficiency, expected from their rotary equivalents, but in several applications this reduction in performance is more than compensated for by convenience and robustness. In this master thesis, first it has. described Linear Induction Motors (LIM), their construe tions, and related equations. Acording to this purpose this study concludes with a review of the analytical technique used to obtain the performance of LIM. A description of direct-solution method is shortly given. Then, conventional DC motors have been studied and given their characteristic specifications with related equations. After that, Linear Induction Motors have been compared with conventional DC motors in theory and in equations. It has been followed by the use of LIM for industrial pruposes and for their applications to transprot propulsion and levitation on guieded vehicles. Finally, it has been made a conclusion for LIM and their applications in industry and especially in transport. Despite the problems associated with reduced performance owing to their end-effects, the advantages of using a linear motor can sometimes produce a convenient and economical solution to drive requirements. In the very near future, the use of LIM owing to the fast progress of ' sol id-state switching circuits will increase and it will give much more convenient solutions with compared their conventional equivalents.
